Chapter 2. Enhancements
The enhancements made to AMQ Streams 1.2.
2.1. Container images
This release includes the following changes to the management of container images for AMQ Streams on OpenShift.
2.1.1. New image registry
All AMQ Streams container images are now hosted on the new Red Hat Registry, registry.redhat.io. Unlike registry.access.redhat.com, the new registry requires authentication for access to container images.
Your OpenShift installation should be already connected and authenticated against the new registry. If it is not authenticated, you can configure your installation according to the OpenShift version:
- If using OpenShift 3.11, see Creating Service Accounts and Authentication Tokens for the Red Hat Registry.
- If using OpenShift 4.1, see Authentication enabled Red Hat registry.
Alternatively, you can create your own OpenShift Secret with the registry credentials, and configure AMQ Streams to use it in the STRIMZI_IMAGE_PULL_SECRETS environment variable in the Cluster Operator configuration or through the imagePullSecrets property in the template of your custom resource.
Additional resources
2.1.2. Reduced number of images
The number of container images for AMQ Streams has been significantly reduced. Four container images are now provided:
| AMQ Streams Component | Container Image |
|---|---|
| Cluster Operator |
|
| Kafka version 2.1 |
|
| Kafka version 2.2 |
|
| AMQ Streams Kafka Bridge (Tech Preview) |
|
Previous releases of AMQ Streams provided separate images, for example, for Kafka Connect. These images have been incorporated into the Cluster Operator and Kafka images.
This release includes a new image for the AMQ Streams Kafka Bridge (as a Technology Preview).
| Image | Incorporates |
|---|---|
| amq-streams-operator |
|
| amq-streams-kafka-2.1 |
|
| amq-streams-kafka-2.2 |
|
| amq-streams-kafka-bridge | New image |
You can access the AMQ Streams container images in the Red Hat Container Catalog.
