1.21. Red Hat OpenShift Serverless 1.28

OpenShift Serverless 1.28 is now available. New features, updates, and known issues that pertain to OpenShift Serverless on OpenShift Container Platform are included in the following notes.

중요

OpenShift Container Platform 4.13 is based on Red Hat Enterprise Linux (RHEL) 9.2. RHEL 9.2 is yet to be submitted for Federal Information Processing Standards (FIPS) validation. Although Red Hat cannot commit to a specific timeframe, we expect to obtain FIPS validation for RHEL 9.0 and RHEL 9.2 modules, and later even minor releases of RHEL 9.x. Information on updates will be available in the Compliance Activities and Government Standards Knowledgebase article.

1.21.1. New features
링크 복사

  • OpenShift Serverless now uses Knative Serving 1.7.
  • OpenShift Serverless now uses Knative Eventing 1.7.
  • OpenShift Serverless now uses Kourier 1.7.
  • OpenShift Serverless now uses Knative (kn) CLI 1.7.
  • OpenShift Serverless now uses Knative broker implementation for Apache Kafka 1.7.
  • The kn func CLI plug-in now uses func 1.9.1 version.
  • Node.js and TypeScript runtimes for OpenShift Serverless Functions are now Generally Available (GA).
  • Python runtime for OpenShift Serverless Functions is now available as a Technology Preview.
  • Multi-container support for Knative Serving is now available as a Technology Preview. This feature allows you to use a single Knative service to deploy a multi-container pod.

  • In OpenShift Serverless 1.29 or later, the following components of Knative Eventing will be scaled down from two pods to one:

    • imc-controller
    • imc-dispatcher
    • mt-broker-controller
    • mt-broker-filter
    • mt-broker-ingress

  • The serverless.openshift.io/enable-secret-informer-filtering annotation for the Serving CR is now deprecated. The annotation is valid only for Istio, and not for Kourier.

    With OpenShift Serverless 1.28, the OpenShift Serverless Operator allows injecting the environment variable ENABLE_SECRET_INFORMER_FILTERING_BY_CERT_UID for both net-istio and net-kourier.

    If you enable secret filtering, all of your secrets need to be labeled with networking.internal.knative.dev/certificate-uid: "<id>". Otherwise, Knative Serving does not detect them, which leads to failures. You must label both new and existing secrets.

    In one of the following OpenShift Serverless releases, secret filtering will become enabled by default. To prevent failures, label your secrets in advance.

1.21.2. Known issues

  • Currently, runtimes for Python are not supported for OpenShift Serverless Functions on IBM Power, IBM zSystems, and IBM® LinuxONE.

    Node.js, TypeScript, and Quarkus functions are supported on these architectures.

  • On the Windows platform, Python functions cannot be locally built, run, or deployed using the Source-to-Image builder due to the app.sh file permissions.

    To work around this problem, use the Windows Subsystem for Linux.

  • KafkaSource resources created before Red Hat OpenShift Serverless 1.27 get stuck when being deleted. To work around the issue, after starting to delete a KafkaSource, remove the finalizer from the resource.
