The Leap
API Connect Version 5
• In 2018, the latest release of API Connect was made available.
Now with implementation based on Docker and Kubernetes, these
capabilities present new challenges/questions to existing API
Connect customers running on version 5.0.x in OVAs. Customers
have many cloud options and understanding the nuances when
deploying to these clouds will make the leap easier.
• In this session you will learn how to thoughtfully approach the new
version and help you prepare to the new opportunities with the
latest version.

Lesson Learned
• Last year I spent a good deal of time working with customers that
have APIC v5.0.
• What I have learned from these experiences?
1. Test the waters. Understanding the new version.
2. Plan appropriately
3. Prepare for change
4. Assemble the team
 Get training or do some self study on Kubernetes
 Re-think previous provisioning estimates
– Setup takes longer than you think
5. Getting into the swing of things with the new features/updates

1. Understanding v2018
IBM API Connect Version 2018 delivers the following features:
• The ability to deploy IBM API Connect micro-services through Docker, and managed
with Kubernetes, to take advantage of the Kubernetes auto-scaling capabilities,
while still having the option to deploy as an Open Virtualization Format (OVF)
package.
• Advanced multi-cloud deployment capabilities with the ability to deploy portal,
gateway, and analytics services separate from API Manager in various IBM and
other cloud environments.
• Complete representational state transfer (REST) and command language interpreter
(CLI) coverage of API Connect functionality for enhanced DevOps functionality.
• Date-based versioning, with year.quarter identifying when the version was released,
to help your organization better manage the API Connect support lifecycle. For more
information, see IBM API Connect™ v2018.x Support Lifecycle.
• The Developer Portal is now based on the Drupal 8 content management system,
which enables more advanced, flexible, and powerful customization capabilities.
Drupal 8 also enables support for HTTP/2 which, among many benefits, can
increase the speed and performance of your site.

API Development
• Docker & Kubernetes
• Install Assist (apicup)
• HA, Availability Zones and
Disaster Recovery
• New APIC configurations
• Backup/Restore
• Cloud Networks
• Cloud Security
• Sharing on-premise LDAP
• Troubleshooting

2. Plan your v2018 Journey
• Plan and make considerations for:
 Topology descriptions, performance conditions, and cloud limitations
 Purchase/estimate cloud resources, security and firewall setup
 Procure low latency file storage
 Backup/Restore, HA and DR
 Network segregation, including VNETs and ExpressRoutes etc.
 Working with disparate groups
 Working under Agile sprints
• Development
 Initial creation in DEV mode
 How to troubleshoot, getting logs etc.
 Creating non-development environments (Standard mode) and
testing in new environment
 Deploying to different gateways
 Moving to Production (hardening and heavy volumes)

3. Preparing for v2018
• Get familiar with Kubernetes
 K8S Basics
 Kubectl commands
• Learn DataPower for Docker
 Custom DataPower services?
 Enabling the WebGUI
• Review What’s new and updated in API Connect 2018

Kubernetes
Learn all this stuff:
• Containers (you can choose Docker, or learn some acronyms and
figure out what they mean and how to use them)
• How to actually containerize your code (i.e. write a Docker file or
something else)
• Kubernetes basics & how to write a manifest
• Probably how to use kubectl
• Maybe how to write a Helm chart…
• Understanding Install Assist (apicup)

Example: Must gather
If deployed via Kubernetes, provide the output of the following commands:
• `kubectl version`
• `helm version`
• Collect Helm release values for each APIConnect helm chart that is deployed with: `helm get values
$APIC_RELEASE --all`
• `helm ls -a`
• `kubectl get pods -a -n <namespace>`
• `kubectl get endpoints -a -n <namespace>`
• `kubectl get ingress -a -n <namespace>`
• `apicup version --semver`
• `kubectl -n kube-system logs -l component=kube-apiserver > kube-apiserver.out`
• `kubectl -n kube-system logs -l component=kube-controller-manager > kube-controller-manager.out`
• `kubectl -n kube-system logs -l component=kube-scheduler > kube-scheduler.out`
• `kubectl -n kube-system get events > kube-system-events.out`
• `kubectl get pvc -n <namespace>`
• `kubectl describe pods -n <namespace>`
• For installation issues: Output of failing command when issued with `--debug` at the end.
• Collect log files for all pods in a namespace with the attached script ( get_pod_logs.zip ) and upload resulting
apic-logs.tgz. It will need slight modification prior to execution. Alternatively, a script can be created from the
content found below

What’s New or Updated
Install/Setup
 2 flavors both based on Kubernetes
 Cloud based running on K8S
 OVA running K8S under the covers
 APICUP (install assist) is required for OVA installations
 New topology setup (Gateway + Analytics)
 New server (Analytics separated from APIM)
 Docker Gateway used in K8S implementations
 Log gathering a tedious task in K8S
 Availability Zones is new concept
 HA Quorum requirements
Development
 LifeCycle changes
 Toolkit no longer has Assemble Testing
 CLI changes supporting user registries
 No longer upload user-policies via APIM. Update it using CLI
 Access to DataPower not enable OOB
 Provider OAuth2 API has changed.

Minimal Prep for migration
• Upgrades will be side by side, not update in place
• Upgrade to latest version of V5. (v5.0.8.5)
 Supports new backup that outputs JSON
• Custom DataPower services
 Identify Non-Custom User Policies that are referenced on DataPower
• Custom CLI calls using APIs
 API calls may have been updated, no longer exist or replaced with new
security and parameters
• In OVA implementation ensure you provision additional resources
on your VSphere environment.

4. Assemble the Team
• It takes a village when embarking on a Cloud implementation of
K8S
• Keep in mind that:
 Your prior operation team may be on-premise and now new resources
will need to understand the APIs, components and troubleshooting
techniques
 The networking resources may also be different from your on-premise
team so there won’t be established patterns they can use. They will
need to understand the requirements.
 Security needs to be clearly defined as well as
authentication/authorization.
 Your K8S install resources will need to understand how API Connect
using K8S handles ingress, SSL and certificates as well as setting up
HA
 Developers from v5 will need to learn how to troubleshoot as well as
learn the changes that occurred in v2018

5. Getting into the swing of it
Adjusting to change
 API Connect Delivery schedule and
Documentation
 Getting Log information
 Cloud specific environments
 Missing capabilities from V5
 Changes from v5 to v2018
 DataPower GUI access
 Custom User Policies additions
 OAuth2 updates (OAuth Provider API)
