Tales of Training: Scaling CodeLabs with Swarm Mode and Docker-Compose
1 like616 views
Why does any "code lab workshop" or live demo are always such a challenge? A wise sysadmin once told me: “Get your hand dirty with the production to learn”. So I want to tell you a story of getting hand dirties, by creating a code lab environment considered as production. This story will show that we can build a reproducible environment for code-labs workshops, by using the Docker “tools”: the Engine, Swarm Mode, Docker-Compose, Moby, LinuxKit. Following the spirit of “Play With Docker”, but generalized at any service collection, this Codelab toolkit has been used on code-labs workshops of 120+ people. That path was not a free lunch, but the lessons learned will give you an idea on how a training environment can be efficiently done with Compose and Swarm Mode, by treating it as a “production” platform, tackling the plumbing “youth” limitations for the better of your use case. As a trainer, I never learned so much than building something to teach people someone else: this the story I want to tell you, the tale of using Docker as a tool of MASSIVE KNOWLEDGE SHARING, which is the root of growing our industry together.

Docker?!?! But I'm a SysAdmin
Docker?!?! But I'm a SysAdminDocker, Inc. Your developers just walked into your cube and said: "Here's the new app, I built it with Docker, and it's ready to go live." What do you do next? In this session, we'll talk about what containers are and what they are not. And we'll step through a series of considerations that need to be examined when deploying containerized workloads - VMs or Container? Bare Metal or Cloud? What about capacity planning? Security? Disaster Recovery? How do I even get started?

Docker Online Meetup: Announcing Docker CE + EE
Docker Online Meetup: Announcing Docker CE + EEDocker, Inc. Docker Community Edition (CE) and Enterprise Edition (EE) are the best expressions of the Docker Platform to date. Whether you’re a developer, an ops team or a enterprise IT-team member, and no matter the infrastructure, Docker CE and EE gives you a way to install, upgrade and maintain Docker with the support and assurances required for your particular workload.
Both Docker CE and EE are available on a wide range of popular operating systems (including Windows Server 2016) and cloud infrastructure. Developers and devOps have the freedom to run Docker on their favorite infrastructure without risk of lock-in.
Michael Friis will give an overview of both editions and highlight the big enhancements to the lifecycle, maintainability and upgradability of Docker.
DCSF19 How To Build Your Containerization Strategy 
DCSF19 How To Build Your Containerization Strategy Docker, Inc. Lee Namba, Docker
The Docker Enterprise container platform helps organizations deploy and manage applications faster and it secures the application pipeline at a lower cost than traditional application delivery models. But it takes more than just great technology to achieve the desired results. The organization and culture of your enterprise directly impacts what you transform, how it’s done, and who does it. Success requires a strategy for how you will govern the container platform environment, how to assess your application estate, what your delivery pipeline will look like, and how to ensure developers, operators, security teams and others play nicely together. In this talk I will cover topics such as different types of workloads (legacy, microservices, FaaS, big data and more), how your org chart can influence whether you deploy CaaS (Containers as a Service) vs CLaaS (Clusters as a Service), how "shifting left" can determine if you can outsource, centralized vs distributed CI/CD and how containers play a role, transforming your pets into cattle, how giant whale balloons are used for onboarding, and a prescriptive and comprehensive methodology for successfully deploying containers into your enterprise.
DockerCon EU 2015: Placing a container on a train at 200mph
DockerCon EU 2015: Placing a container on a train at 200mphDocker, Inc. Presented by Casper S. Jensen, Software Engineer, Uber
At Uber, we've been introducing Docker to give service owners more control over their environments. However, everything at Uber is moving very fast so we have had to do it a way such that Docker fitted into the existing infrastructure and services could be migrated seamlessly to Docker without any service interruptions. In this talk we will talk about the challenges we faced while doing this, such as handling both non-Docker and Docker builds, image replication, integration with our deployment systems and other challenges when deploying Docker at scale.
DCEU 18: Docker Containers in a Serverless World
DCEU 18: Docker Containers in a Serverless WorldDocker, Inc. Jules Testard - Software Engineer, Docker Inc
Since the advent of AWS Lambda in 2014, the Function as a Service (FaaS) programming paradigm has gained a lot of traction in the cloud community. Since then, interest has increased for developers and entreprises to build their own open source solutions on top of Kubernetes. A number of competing frameworks in this space have been developed. In this talk, we will look at three specific frameworks (OpenFaas, Nuclio and FN) and for each framework we will: Show how to create, deploy, and invoke a function using that framework Show how Docker images and containers are used by each framework under the hood Investigate how the frameworks leverage KNative to build, ship and run applications on Kubernetes
Kubernetes in Docker
Kubernetes in DockerDocker, Inc. 1. Docker EE will include an unmodified Kubernetes distribution to provide orchestration capabilities alongside Docker Swarm.
2. When running mixed workloads across orchestrators, resource contention is a risk and it is recommended to separate workloads by orchestrator on each node for now.
3. Docker EE aims to address the shortcomings of running mixed workloads to better support this in the future.
Containerizing Hardware Accelerated Applications
Containerizing Hardware Accelerated ApplicationsDocker, Inc. Many applications allow you to use hardware such as GPUs and FPGAs for acceleration. Common examples include media processing and offloading highly parallel work to a GPU. Applications that use accelerators are resource heavy and have stacks spanning kernel and user space; accelerators often have their own requirements for operating system support and kernel versions. While it may not seem intuitive to containerize this type of application, the use of containers provides benefits such as reduced setup time from container reuse, reduction in dependency conflicts and dependency on a specific operating system, and easier updates.
In this session I show a media processing stack, making use of containers alongside a GPU. Specifically, I explain the kernel and user space divide of a hardware-accelerated transcode application using a device exposed to the container. This specific stack is an interesting case because of its dependency on hardware, use of a custom kernel and libraries, and operating system requirements. Our investigations have shown the use of containers has minimal performance overhead compared to running natively. Furthermore, we can quickly deploy on other machines with reduced configuration effort. There are some aspects of the application not suited to containerization, however. Since the application relies on a custom kernel, the use of containers does not necessarily increase portability. Improvement in this area would require rethinking how the applications are developed and distributed. Other areas of innovation include things such as Docker plugins to check for compatibility between the container software and host kernel.
DCEU 18: Building Your Development Pipeline
DCEU 18: Building Your Development PipelineDocker, Inc. This document discusses building a development pipeline using containers. It outlines using containers for building images, automated testing, security scanning, and deploying to production. Containers make environments consistent and reproducible. The pipeline includes building images, testing, security scanning, and promoting images to production. Methods discussed include using multi-stage builds to optimize images, leveraging Buildkit for faster builds, and parallel testing across containers. Automated tools are available to implement rolling updates and rollbacks during deployments.
Docker on Docker
Docker on DockerDocker, Inc. This document discusses Docker Inc's transition to running their infrastructure on Docker EE (Docker Enterprise Edition). Some key points:
- Previously Docker Inc ran their infrastructure (Docker Hub, Docker Store, etc) on a collection of Docker hosts managed imperatively without orchestration.
- They transitioned to running everything on Docker EE for the benefits of declarative orchestration using Docker Swarm, access controls, and resource management.
- The transition was done by changing the orchestration layer only, without changing applications, containers, logs, metrics, etc. This allowed them to gradually transition services to Docker EE.
- Running as a customer of their own product has provided Docker Inc valuable insights into best practices, feature requests
Packaging software for the distribution on the edge
Packaging software for the distribution on the edgeDocker, Inc. At GE Digital, in the Asset Performance Management space, we need to supply an edge solution that impacts both on-premise and data transmission to the cloud. Our current edge solutions are relatively simplistic, but as our technologies mature along with our customers’ needs, we’re finding that we need to grasp a more fog computing-based approach where we include more intelligence, more computing power, at the edge. Along with this computative power, we need to better remotely manage these systems – to be able to monitor progress and diagnose problems – a technology that would enable us to containerize, to better manage, our software bundlings and deployments.
We found that Windows Docker seemed to fit the bill -- much of the technologies that live at our edge solutions are Windows OS based (as the customers’ main platforms are Windows OS based). This presentation reviews the approach that we took to repackage one of our main APM on-premise solutions using Windows Docker. We’ve created a prototype which we’re looking forward to productize and enable the capability of remote management to thousands of deployments.
The presentation also contains a video demo of the running system. The on-prem APM system will demonstrate the usage of Docker networking along with docker volumes and three (3) docker containers – will discuss the construction of the images, and nuances, of execution of the running docker containers.

DCEU 18: App-in-a-Box with Docker Application Packages
DCEU 18: App-in-a-Box with Docker Application PackagesDocker, Inc. Michael Irwin - Application Architect, Virginia Tech
Docker Application Packages is an experimental tool that makes it easy to share multi-service applications. Create a Compose file, package it in an image, and voilà! You now have an "app-in-a-box"! Not convinced yet? No worries! It took a while for me to be convinced too! In this session, we'll start off by diving into how Docker Application Packages actually works, which will help us understand the use cases. We'll see how dev environments can hook in to this app-in-a-box by replacing the service being worked on with a dev container. Then we'll move on to see how end-to-end functional tests are much easier to run. And, finally, we'll see how to maintain an "app-in-a-box" with the latest versions of each component in a CI/CD pipeline, allowing for a unique app-in-a-box for each feature branch under development. Lots of good material! And lots of live demos!
Advanced Access Control with Docker EE
Advanced Access Control with Docker EEDocker, Inc. The sharing of computing resources among applications and users solves many challenges and presents opportunities for enterprise IT. It leads to better infrastructure efficiency and the specialization of responsibilities in the IT stack. Shared resources across diverse organizations and applications also introduce new hurdles. Tenants need to access their resources securely and with complete privacy from other tenants. This requires secure segmentation, access control, and more.
Container multi-tenancy is much more than cgroups and namespaces. This talk focuses on the advanced Access Control features in Docker Enterprise Edition that provide the fine-grained control to segment cluster resources. This includes how to design fine-grained roles, the architecture and grouping of resources, and how to apply these as Access Control policy. Walk through practical examples from current production designs and understand how they can be applied to your organization.

During this talk, we will discuss how Assa Abloy is using Docker EE to build a Common Access Technology platform based on microservices running in containers. We will share the architectural decisions that were made and how those resulted in deploying Docker EE on AWS. We will discuss both the technical challenges Assa Abloy encountered and the organizational changes that affected the way they develop their software. Next, we will share how Assa Abloy plans to roll out on a global scale.
Modernizing .NET Apps
Modernizing .NET AppsDocker, Inc. Docker has the potential to revolutionize how we build, deliver, support and even design software. But it doesn't have to be a violent revolution. The end goal might be breaking your existing ASP.NET monolith into microservices which run cross-platform on .NET Core, but the first step can be as simple as packaging your whole .Net Framework application as-is into a Docker image and running it as a container.
In this session, we'll take an existing ASP.NET WebForms application and package it as a Docker image, which can run in a container on Windows Server 2016 and Windows 10. We'll show you how to run the app and a SQL Server database in Docker containers on Windows, and how to use Docker Compose to define the structure of a distributed application.
Then we'll iteratively add functionality to the app, making use of the Docker platform to modernize the monolith without a full rebuild. We'll take a feature-driven approach and show you how Docker makes it easy to address performance, usability and design issues.y and design issues.

Looking Under The Hood: containerD
Looking Under The Hood: containerDDocker, Inc. As we move to our application units to containers most people are asking themselves the question about orchestrator choice. That is not the only choice that’s important, what about the underlying container runtime? In this talk, we will look at why you would use containerD with runC with both Swarm and Kubernetes, but other uses for ContainerD like container OS’s to ship immutable infrastructure.
Repainting the Past with Distributed Machine Learning and Docker
Repainting the Past with Distributed Machine Learning and DockerDocker, Inc. "A picture is worth a thousand words” – Frederick R Bernard. Video is worth thousands more. With millions of hours of black and white video footage circulating around the internet or locked indefinitely in storage archives, their true stories and colours have been lost forever. With the cost of breathing new colour into these fragments of history being $3000 per minute, the vast majority of this footage will never be truly appreciated. Wouldn’t it be revolutionary if we could combine the latest cutting edge research in machine learning with the power unleashed by distributed computing with Docker to solve this problem?
Using recurrent convolutional neural networks combined with advanced scheduling, distribution, and orchestration made possible only by Docker, we are able to realistically hallucinate colour back into any black and white video. And with machine learning, we can cut the costs dramatically by automating the process of painting each frame, resulting in a realistic high-quality video in record time. We will demo this and much more in our talk “Repainting the past with distributed machine learning and Docker

Next, we will share how Assa Abloy plans to roll out on a global scale.
Modernizing .NET Apps
Modernizing .NET AppsDocker, Inc. Docker has the potential to revolutionize how we build, deliver, support and even design software. But it doesn't have to be a violent revolution. The end goal might be breaking your existing ASP.NET monolith into microservices which run cross-platform on .NET Core, but the first step can be as simple as packaging your whole .Net Framework application as-is into a Docker image and running it as a container.
In this session, we'll take an existing ASP.NET WebForms application and package it as a Docker image, which can run in a container on Windows Server 2016 and Windows 10. We'll show you how to run the app and a SQL Server database in Docker containers on Windows, and how to use Docker Compose to define the structure of a distributed application.
Then we'll iteratively add functionality to the app, making use of the Docker platform to modernize the monolith without a full rebuild. We'll take a feature-driven approach and show you how Docker makes it easy to address performance, usability and design issues.y and design issues.

Looking Under The Hood: containerD
Looking Under The Hood: containerDDocker, Inc. As we move to our application units to containers most people are asking themselves the question about orchestrator choice. That is not the only choice that’s important, what about the underlying container runtime? In this talk, we will look at why you would use containerD with runC with both Swarm and Kubernetes, but other uses for ContainerD like container OS’s to ship immutable infrastructure.
Repainting the Past with Distributed Machine Learning and Docker
Repainting the Past with Distributed Machine Learning and DockerDocker, Inc. "A picture is worth a thousand words” – Frederick R Bernard. Video is worth thousands more. With millions of hours of black and white video footage circulating around the internet or locked indefinitely in storage archives, their true stories and colours have been lost forever. With the cost of breathing new colour into these fragments of history being $3000 per minute, the vast majority of this footage will never be truly appreciated. Wouldn’t it be revolutionary if we could combine the latest cutting edge research in machine learning with the power unleashed by distributed computing with Docker to solve this problem?
Using recurrent convolutional neural networks combined with advanced scheduling, distribution, and orchestration made possible only by Docker, we are able to realistically hallucinate colour back into any black and white video. And with machine learning, we can cut the costs dramatically by automating the process of painting each frame, resulting in a realistic high-quality video in record time. We will demo this and much more in our talk “Repainting the past with distributed machine learning and Docker
My Journey To Go
My Journey To GoDocker, Inc. Before becoming a Gopher, Ashley was a professional photographer, which explains her talent and dedication to creating unique Gopher artwork. However, she found that photography wasn’t paying the bills and with a family to feed, she turned to programming. Prior to enrolling at Hackbright Academy (a software engineering bootcamp for women), Ashley had done some front-end work building websites for photographers and working on SEO. Bootcamp had promised to teach her all of the things you need to know to be an engineer, but despite having the “official” business card 12 weeks later, she didn’t feel like a Software Engineer. Ashley found herself writing Python and working as a Community Manager at Rackspace, which is when she met a Gopher who would completely change her trajectory.
In 2014, Ashley met and became quick friends with Steve Francia @spf13, who made her abandon Python and never look back. Steve had been teaching an introductory course to Go, and urged Ashley to help teach the course, where her fresh perspective on Go was an asset. Ever since then, Ashley has been a valued member and a key contributor in building the Go community.
Join this session to learn how teaching others (even though Ashley was new herself) got her involved in an awesome open source community and ultimately changed her career path. Ashley will share how she contributed without committing code, and her lessons and tips on how anyone can get involved in OSS communities and make an impact.
Cilium: Kernel Native Security & DDOS Mitigation for Microservices with BPF
Cilium: Kernel Native Security & DDOS Mitigation for Microservices with BPFDocker, Inc. We have introduced Cilium at DockerCon US 2017 this year. Cilium provides application-aware network connectivity, security, and load-balancing for containers. This talk will follow up on the introduction and deep dive into recent kernel developments that address two fundamental questions: How can I provide application-aware security and routing efficiently without overhead embedded into every service? How can container hosts protect themselves from internal and external DDoS attacks? The solutions include:
kproxy: a kernel-based socket proxy which allows for application-aware routing and security enforcement with minimal overhead.
XDP: A lightning-fast packet processing datapath using BPF. The technology is intended for DDoS mitigation, load-balancing, and forwarding.
This talk will deep dive into these exciting technologies and show how Cilium makes BPF and these kernel features available on Linux for your Docker containers.
The Value Of Diverse Experiences
The Value Of Diverse ExperiencesDocker, Inc. Some things in life are within your control, while others are not. And if you belong to an underrepresented demographic, this translates into additional challenges when it comes to having the career you want. Finding a mentor, participating in resource groups, and building your network are all great ways to help you climb the corporate ladder (or more accurately, the jungle gym). For me, refusing to put invisible guardrails around myself led me down an interesting path and allowed me to take charge of my career.
In this session, I’ll share personal anecdotes about my journey from a hardware engineer working on 64 nm chips, to software engineer working on large scale distributed systems, to a manager, where I have the opportunity to make a greater impact by building a strong and diverse team. I’ll cover my learnings, and give attendees tips on how to define what a successful career is for you, and keys to building a diverse team.
Continuous Packaging is also Mandatory for DevOps
Continuous Packaging is also Mandatory for DevOpsDocker, Inc. While DevOps are comfortable with continuous integration and automatic tests, the area of continuous packaging has not been given the attention it deserves.
Even with containers, delivering an application using software packages provides multiple advantages with regards to file-based installation: it allows to manage dependencies more easily, to provide metadata, checksum, and signature mechanisms, to deal with packages repositories.
But doing that in a continuous packaging approach means that the generation of these packages is fully automated and part of the build process of the software. As a consequence, it eases the various steps of a solution lifecycle (controlled impact of installation/uninstallation,
identical deliveries up to the customer, avoidance of code or metadata duplication)
This presentation will detail the methodological approach around continuous packaging and demonstrate how this can be put in place using an Open Source tool such as project-builder.org and how this allows the MondoRescue project to deliver packages at will for lots of distribution tuples through the same number of Docker containers.
Experience the Swarm API in Virtual Reality
Experience the Swarm API in Virtual RealityDocker, Inc. Docker has a CLI that is a great starting point for programming and automation, but did you know that it's really just a wrapper for the Docker Engine REST API?
The Engine has an accessible, well-documented API that's super easy to use.
In this session, you'll learn how to consume the Docker API in different ways and be encouraged to build your own tools.
We built an app using VueJS and A-Frame that uses the API to visualize Docker Swarm in Web-VR.
The combination of these functional, declarative web technologies is a good way to build immersive, interactive experiences around infrastructure that are easily accessible to others.
More people should be building these kinds of tools.
We'll show how we started building the app in Swarm and how we're able to develop against the API with hot-module-reloading. (This totally works in VR!)
You'll also get a run down how we leveraged existing components from the community in order to quickly prototype our application using Docker Stacks.
Ultimately, everyone will have a chance to experience interacting with a Swarm through the magic window of their phones.
VR is a personal, educational medium. We should be building these virtual worlds around all the components of the Moby Project.
Our hope is that we can share ideas and motivate others to create more compelling Docker and infrastructure tooling with Virtual Reality.
Expect to leave the session wowed by the power of VR and informed about how to leverage Docker's REST API for your own endeavors.
Docker to the Rescue of an Ops Team
Docker to the Rescue of an Ops TeamDocker, Inc. In this talk, we'll discover how Docker comes to the rescue of the Ops Team, while rebuilding from scratch our monitoring infrastructure. We'll start by quickly describing the challenges, to focus on why and how using docker saved the project. From fixing dependencies and isolation issues, implementing rolling upgrades and new features hot addition, to building a completely modular, scalable and resilient infrastructure, we'll talk about why CI/CD workflows, docker tooling and Docker Swarm were the key to success.
Skynet vs. Planet of The Apes: Duel!
Skynet vs. Planet of The Apes: Duel!Docker, Inc. Singularity happened. Machines have risen. Skynet, the massively distributed AI will soon expand its grip and its army of robots will spread across the whole planet. Fortunately, a great ape army is standing across their way to put an end to this supremacy of steel.
The battle will be epic!
On one side we have Skynet, an automated, self-healed, hybrid Docker platform and skynet application that has become indestructible. Playing the army of Apes, is a dedicated platform hosting Netflix's Simian Army and other flavors.
Will Skynet resists the relentless assaults of the great ape army?
Through this fantasy, we'll first cover all the technologies concretely used to set up the platforms and run the battle (linuxkit, infrakit, & swarm mode, and even raspberry devices among others), while we'll step back in the second part to address the subsequent architecture stakes involved: reliability, scalability, edge computing, immutability, microservices, hybridization, distributed storage. Most of all, you'll understand the importance of the synergies implied between the platforms and the app's design to achieve such a result.
The Truth Behind Serverless
The Truth Behind ServerlessDocker, Inc. The document discusses serverless computing and functions as a service (FaaS) platforms. It provides an overview of Amazon Lambda including details on storage limits, duration limits, memory sizes, and how functions are executed in containers. It also summarizes the key points of Amazon's serverless manifesto and lists several FaaS providers and event sources. The document raises questions about the challenges of orchestrating containers at scale and implementing serverless architectures for low latency and state management.
LinuxKit Deep Dive
LinuxKit Deep DiveDocker, Inc. We open-sourced LinuxKit in April 2017 at DockerCon in Austin. In this session, we'll take a detailed look at some advanced topics of LinuxKit ranging from the general read-only filesystem setup, multi-arch image support for x86_64 and arm64, custom network configuration, and kernel debugging and testing.
Moby and Kubernetes entitlements 
Moby and Kubernetes entitlements Docker, Inc. The document proposes a new system called "entitlements" for defining high-level security profiles and permissions for containers. It would allow defining permissions profiles like "network.admin" instead of low-level options. Entitlements would be attached to container images to define their security properties. The goals are to improve the user experience, support a standard across platforms, and securely tie security profiles to images through signing. Implementation is still needed in Moby and Kubernetes. Feedback is welcomed on usability, default entitlements, and design.
How and Why Prometheus' New Storage Engine Pushes the Limits of Time Series D...
How and Why Prometheus' New Storage Engine Pushes the Limits of Time Series D...Docker, Inc. The Prometheus monitoring system collects and stores time series data to give valuable insights over hosts, containers, and applications. Its storage engine was designed to be multiple orders of magnitude faster and more space efficient than, say, RRD or SQL storage. However, with the rise of orchestration systems such as Docker Swarm and Kubernetes, and their extensive use of techniques like rolling updates and auto-scaling, environments are becoming increasingly dynamic. This increases the strain on metrics collection systems. To deal with the challenges, a new storage engine has been developed from scratch, bringing a sharp increase in performance and enabling new features.
This talk will describe this new storage engine, its architecture, its data structures, and explain why and how it is well suited to gracefully handle high turnover rates of monitoring targets and provide consistent query performance.
Taking Docker to Production: What You Need to Know and Decide
Taking Docker to Production: What You Need to Know and DecideDocker, Inc. This document provides advice on taking Docker to production. It recommends starting simply by focusing on Dockerfiles and containerizing existing applications before complex orchestration. It also warns against common anti-patterns like using the "latest" tag or trapping data in containers. The document outlines sample swarm architectures and tech stacks and notes that outsourcing non-critical components can simplify operations. It closes by suggesting that an orchestrator may not always be needed and that running one container per VM is a valid approach.
What's New in Docker

Learning Docker from Square One
Learning Docker from Square OneDocker, Inc. Being a newer technology, Docker has yet to make its way into some computer science training programs. College programs, bootcamps, and online resources have yet to jump onto the container train; so, what's the best way for newer engineers to learn Docker from square one? Chloe (former actress turned developer) tells her story about how she went from wondering "What's a Docker?" to helping teach others about Docker and instead asking "What?? You haven't heard of Docker?". This talk is perfect for anyone new to Docker looking for how to get started, or for those interested in learning how to teach Docker to new users.

Containers, Docker, and Microservices: the Terrific Trio
Containers, Docker, and Microservices: the Terrific TrioJérôme Petazzoni One of the upsides of Microservices is the ability to deploy often,at arbitrary schedules, and independently of other services, instead of requiring synchronized deployments happening on a fixed time.
But to really leverage this advantage, we need fast, efficient, and reliable deployment processes. That's one of the value propositions of Containers in general, and Docker in particular.
Docker offers a new, lightweight approach to application portability.It can build applications using easy-to-write, repeatable, efficient recipes; then it can ship them across environments using a common container format; and it can run them within isolated namespaces which abstract the operating environment, independently of the distribution,versions, network setup, and other details of this environment.
But Docker can do way more than deploy your apps. Docker also enables you to generalize Microservices principles and apply them on operational tasks like logging, remote access, backups, and troubleshooting.This decoupling results in independent, smaller, simpler moving parts.
Docker and Puppet for Continuous Integration
Docker and Puppet for Continuous IntegrationGiacomo Vacca Today developers want to change the code, build and deploy often, even several times per day.
New versions of software may need to be tested on different distributions, and with different configurations.
Achieving this with Virtual Machines it’s possible, but it’s very resource and time consuming. Docker provides an incredibly good solution for this, in particular if combined with Continuous Integration tools like Jenkins and Configuration Management tools like Puppet.
This presentation focuses on the opportunities to configure automatically Docker images, use Docker containers as disposable workers during your tests, and even running your Continuous Integration system inside Docker.

Using Kubernetes for Continuous Integration and Continuous Delivery. Java2days
Using Kubernetes for Continuous Integration and Continuous Delivery. Java2daysCarlos Sanchez Learn how to scale your Continuous Integration and Continuous Delivery environment using containers. The Kubernetes project provides a container orchestration solution that greatly simplifies app deployments in large clusters and you can use Jenkins and Kubernetes together to run jobs on-demand.
Building and testing is a great use case for containers, both due to the dynamic and isolation aspects, but it increases complexity when scaling to multiple nodes and clusters.
Jenkins is an example of an application that can take advantage of Kubernetes technology to run Continuous Integration and Continuous Delivery workloads. Jenkins and Kubernetes can be integrated to transparently use on demand containers to run build agents and jobs, and isolate job execution. It also supports CI/CD-as-code using Jenkins Pipelines and automated deployments to Kubernetes clusters. The presentation will allow a better understanding of how to use Jenkins on Kubernetes for container based, totally dynamic, large scale CI and CD.

Build & Deploy Multi-Container Applications to AWS
Build & Deploy Multi-Container Applications to AWSDocker, Inc. Lukonde Mwila, Entelect -
As the cloud-native approach to development and deployment becomes more prevalent, it's an exciting time for software engineers to be equipped on how to dockerize multi-container applications and deploy them to the cloud.
In this talk, Lukonde Mwila, Software Engineer at Entelect, will cover the following topics:
- Docker Compose
- Containerizing an Nginx Server
- Containerizing an React App
- Containerizing an Node.JS App
- Containerizing anMongoDB App
- Runing Multi-Container App Locally
- Creating a CI/CD Pipeline
- Adding a build stage to test containers and push images to Docker Hub
- Deploying Multi-Container App to AWS Elastic Beanstalk
Lukonde will start by giving an overview of how Docker Compose works and how it makes it very easy and straightforward to startup multiple Docker containers at the same time and automatically connect them together with some form of networking.
After that, Lukonde will take a hands on approach to containerize an Nginx server, a React app, a NodeJS app and a MongoDB instance to demonstrate the power of Docker Compose. He'll demonstrate usage of two Docker files for an application, one production grade and the other for local development and running of tests. Lastly, he'll demonstrate creating a CI/CD pipeline in AWS to build and test our Docker images before pushing them to Docker Hub or AWS ECR, and finally deploying our multi-container application AWS Elastic Beanstalk.

Distributed Deep Learning with Docker at SalesforceDocker, Inc. Jeff Hajewski, Salesforce -
There is a wealth of information on building deep learning models with PyTorch or TensorFlow. Anyone interested in building a deep learning model is only a quick search away from a number of clear and well written tutorials that will take them from zero knowledge to having a working image classifier. But what happens when you need to deploy these models in a production setting? At Salesforce, we use TensorFlow models to help us provide customers with insights into their data, and we do this as close to real-time as possible. Designing these systems in a scalable manner requires overcoming a number of design challenges, but the core component is Docker. Docker enables us to design highly scalable systems by allowing us to focus on service interactions, rather than how our services will interact with the hardware. Docker is also at the core of our test infrastructure, allowing developers and data scientists to build and test the system in an end to end manner on their local machines. While some of this may sound complex, the core message is simplicity - Docker allows us to focus on the aspects of the system that matter, greatly simplifying our lives.
The First 10M Pulls: Building The Official Curl Image for Docker Hub
The First 10M Pulls: Building The Official Curl Image for Docker HubDocker, Inc. James Fuller, webcomposite s.r.o. -
Curl is the venerable (yet very modern) 'swiss army knife' command line tool and library for transferring data with URLs. Recently we (the Curl team) decided to build a release for Docker Hub. This talk will outline our current development workflow with respect to the docker image and provide insights on what it takes to build a docker image for mass public consumption. We are also keen to learn from users and other developers how we might improve and enhance the official curl docker image.
Monitoring in a Microservices World
Monitoring in a Microservices WorldDocker, Inc. Fabian Stäber, Instana -
In recent years, we saw a great paradigm shift in software engineering away from static monolithic applications towards dynamic distributed horizontally scalable architectures. Docker is one of the key technologies enabling this development. This shift poses a lot of new challenges for application monitoring, ranging from practical issues (need for automation) to technical challenges (Docker networking) to organizational topics (blurring line between software engineers and operations) to fundamental questions (define what is an application). In this talk we show how Docker changed the way we do monitoring, how modern application monitoring systems work, and what future developments we expect.

COVID-19 in Italy: How Docker is Helping the Biggest Italian IT Company Conti...Docker, Inc. Clemente Biondo, Engineering Ingegneria Informatica -
When the COVID 19 pandemic started, Engineering Ingegneria Informatica Group (1.25 billion euros of revenues, 65 offices around the world, 12.000 employees) was forced to put their digital transformation to the test in order to maintain operational continuity. In this session, Clemente Biondo, the Tech Lead of the Information Systems Department, will share how his company is reacting to this unforeseeable scenario and how Docker-driven digital transformation had paved the path for work to continue remotely. Clemente will discuss learnings moving from colocated teams, manual approaches, email based-business processes, and a monolithic application to a mature DevOps culture characterized by a distributed autonomous workforce and a continuous deployment process that deploys backward-compatible Docker containerized microservices into hybrid multi cloud datacenters an average of twice a day with zero-downtime. He will detail how they use Docker to unify dev, test and production environments, and as an efficient and automated mechanism for deploying applications. Lastly, Clemente shares how, in our darkest hour, he and others are working to shine their brightest light.
Predicting Space Weather with Docker
Predicting Space Weather with DockerDocker, Inc. The document discusses how NOAA's Space Weather Prediction Center transitioned from a monolithic architecture to microservices using Docker. It describes how they started with a small verification project, then replaced their critical GOES satellite data source. This improved developers' morale and delivery speed. They encountered some security issues initially but learned from them. The transition was very successful and allowed them to quickly expand their mission to forecast aviation impacts using scientists' models packaged as Docker services.
Become a Docker Power User With Microsoft Visual Studio Code
Become a Docker Power User With Microsoft Visual Studio CodeDocker, Inc. Brian Christner, 56k + Docker Captain -
In this session, we will unlock the full potential of using Microsoft Visual Studio Code (VS Code) and Docker Desktop to turn you into a Docker Power User. When we expand and utilize the VS Code Docker plugin, we can take our projects and Docker skills to the next level. In addition to using VS Code, we streamline our Docker Desktop development workflow with less context switching and built-in shortcuts. You will learn how to bootstrap new projects, quickly write Dockerfiles utilizing templates, build, run, and interact with containers all from VS Code.
How to Use Mirroring and Caching to Optimize your Container Registry
How to Use Mirroring and Caching to Optimize your Container RegistryDocker, Inc. Brandon Mitchell, Boxboat + Docker Captain -
How do you make your builds more performant? This talk looks at options to configure caching and mirroring of images that you need to save on bandwidth costs and to keep running even if something goes down upstream.
Monolithic to Microservices + Docker = SDLC on Steroids!
Monolithic to Microservices + Docker = SDLC on Steroids!Docker, Inc. Ashish Sharma, SS&C Eze -
SS&C Eze provides various products in the stock market domain. We spent the last couple of years building Eclipse which is an investment suite born in cloud. The journey so far has been very interesting. The very first version of the product were a bunch of monolithic windows services and deployed using Octopus tool. We successfully managed to bring all the monolithic problem to the cloud and created a nightmare for ourselves. We then started applying microservices architecture principles and started breaking the monolithic into small services. Very soon we realized that we need a better packaging/deployment tool. Docker looked like a magical solution to our problem. Since its adoption, It has not only solved the deployment problem for us but has made a deep impact on different aspects of SDLC. It allowed us to use heterogeneous technology stacks, simplified development environment setup, simplified our testing strategy, improved our speed of delivery, and made our developers more productive. In this talk I would like to share our experience of using Docker and its positive impact on our SDLC.
Kubernetes at Datadog Scale
Kubernetes at Datadog ScaleDocker, Inc. Kubernetes networking can be complex to scale due to issues like growing iptables rules, but newer solutions are helping. Pod networking uses CNI plugins like flannel or Calico to assign each pod an IP and allow communication. Service networking uses kube-proxy and iptables or IPVS for load balancing to pods. DNS is used to resolve service names to IPs. While Kubernetes networking brings flexibility, operators must learn the nuances of their specific CNI plugin and issues can arise, but the ecosystem adapts quickly to new needs and changes don't impact all workloads.
Labels, Labels, Labels 
Labels, Labels, Labels Docker, Inc. Andy Clemenko, StackRox -
One underutilized, and amazing, thing about the docker image scheme is labels. Labels are a built in way to document all aspects about the image itself. Think about all the information that the tags inside your clothing carry. If you care to look you can find out everything about the garment. All that information can be very valuable. Now think about how we can leverage labels to carry similar information. We can even use the labels to contain Docker Compose or even Kubernetes Yaml. We can even include labels into the CI/CD process making things more secure and smoother. Come find out some fun techniques on how to leverage labels to do some fun and amazing things.
Using Docker Hub at Scale to Support Micro Focus' Delivery and Deployment Model
Using Docker Hub at Scale to Support Micro Focus' Delivery and Deployment ModelDocker, Inc. Micro Focus uses Docker Hub at scale to support its software delivery and deployment model. Some key points:
- Docker Hub is used as the registry service for Micro Focus container images
- It allows for optimized, secure, reliable and cost-effective software delivery through deployments and updates of container images to customers and partners
- Micro Focus leverages features like private repositories, offline/online access, signing and scanning of images, and integration with CI/CD pipelines
- Over 1,650 organizations, 450 repositories, and 18 teams are used on Docker Hub to manage access and deliver software from Micro Focus
Build & Deploy Multi-Container Applications to AWS
Build & Deploy Multi-Container Applications to AWSDocker, Inc. Lukonde Mwila, Entelect
As the cloud-native approach to development and deployment becomes more prevalent, it's an exciting time for software engineers to be equipped on how to dockerize multi-container applications and deploy them to the cloud.
In this talk, Lukonde Mwila, Software Engineer at Entelect, will cover the following topics:
- Docker Compose
- Containerizing an Nginx Server
- Containerizing an React App
- Containerizing an Node.JS App
- Containerizing anMongoDB App
- Runing Multi-Container App Locally
- Creating a CI/CD Pipeline
- Adding a build stage to test containers and push images to Docker Hub
- Deploying Multi-Container App to AWS Elastic Beanstalk
Lukonde will start by giving an overview of how Docker Compose works and how it makes it very easy and straightforward to startup multiple Docker containers at the same time and automatically connect them together with some form of networking.
After that, Lukonde will take a hands on approach to containerize an Nginx server, a React app, a NodeJS app and a MongoDB instance to demonstrate the power of Docker Compose. He'll demonstrate usage of two Docker files for an application, one production grade and the other for local development and running of tests. Lastly, he'll demonstrate creating a CI/CD pipeline in AWS to build and test our Docker images before pushing them to Docker Hub or AWS ECR, and finally deploying our multi-container application AWS Elastic Beanstalk.
From Fortran on the Desktop to Kubernetes in the Cloud: A Windows Migration S...
From Fortran on the Desktop to Kubernetes in the Cloud: A Windows Migration S...Docker, Inc. Elton Stoneman, Docker Captain + Container Consultant and Trainer
How do you provide a SaaS offering when your product is a 10-year old Fortran app, currently built to run on Windows 10? With Docker and Kubernetes of course - and you can do it in a week (... to prototype level at least).
In this session I'll walk through the processes and practicalities of taking an older Windows app, making it run in containers with Kubernetes, and then building a simple API wrapper to host the whole stack as a cloud-based SaaS product.
There's a lot of technology here from a real world case study, and I'll focus on:
- running Windows apps in Docker containers
- building a .NET Core API which can run in Linux or Windows containers
- running the stack in Kubernetes with Docker Desktop locally and AKS in the cloud
- configuring AKS workloads in Azure to burst out to Azure Container Instances
And there's a core theme to this session: Docker and Kubernetes are complex technologies, but they're the key to modern development. If you invest time learning them, they make projects like this simple, portable, fast and fun.

Crazy Incentives and How They Kill Security. How Do You Turn the Wheel?
Crazy Incentives and How They Kill Security. How Do You Turn the Wheel?Christian Folini Everybody is driven by incentives. Good incentives persuade us to do the right thing and patch our servers. Bad incentives make us eat unhealthy food and follow stupid security practices.
There is a huge resource problem in IT, especially in the IT security industry. Therefore, you would expect people to pay attention to the existing incentives and the ones they create with their budget allocation, their awareness training, their security reports, etc.
But reality paints a different picture: Bad incentives all around! We see insane security practices eating valuable time and online training annoying corporate users.
But it's even worse. I've come across incentives that lure companies into creating bad products, and I've seen companies create products that incentivize their customers to waste their time.
It takes people like you and me to say "NO" and stand up for real security!

Slack like a pro: strategies for 10x engineering teams
Slack like a pro: strategies for 10x engineering teamsNacho Cougil You know Slack, right? It's that tool that some of us have known for the amount of "noise" it generates per second (and that many of us mute as soon as we install it 😅).
But, do you really know it? Do you know how to use it to get the most out of it? Are you sure 🤔? Are you tired of the amount of messages you have to reply to? Are you worried about the hundred conversations you have open? Or are you unaware of changes in projects relevant to your team? Would you like to automate tasks but don't know how to do so?
In this session, I'll try to share how using Slack can help you to be more productive, not only for you but for your colleagues and how that can help you to be much more efficient... and live more relaxed 😉.
If you thought that our work was based (only) on writing code, ... I'm sorry to tell you, but the truth is that it's not 😅. What's more, in the fast-paced world we live in, where so many things change at an accelerated speed, communication is key, and if you use Slack, you should learn to make the most of it.

Could Virtual Threads cast away the usage of Kotlin Coroutines - DevoxxUK2025
Could Virtual Threads cast away the usage of Kotlin Coroutines - DevoxxUK2025João Esperancinha This is an updated version of the original presentation I did at the LJC in 2024 at the Couchbase offices. This version, tailored for DevoxxUK 2025, explores all of what the original one did, with some extras. How do Virtual Threads can potentially affect the development of resilient services? If you are implementing services in the JVM, odds are that you are using the Spring Framework. As the development of possibilities for the JVM continues, Spring is constantly evolving with it. This presentation was created to spark that discussion and makes us reflect about out available options so that we can do our best to make the best decisions going forward. As an extra, this presentation talks about connecting to databases with JPA or JDBC, what exactly plays in when working with Java Virtual Threads and where they are still limited, what happens with reactive services when using WebFlux alone or in combination with Java Virtual Threads and finally a quick run through Thread Pinning and why it might be irrelevant for the JDK24.
