Synopsis

Type/Severity

Bug Fix Advisory None

Topic

Red Hat OpenShift Container Platform release 4.6.20 is now available with updates to packages and images that fix several bugs.

Description

Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution designed for on-premise or private cloud deployments.

This advisory contains the container images for Red Hat OpenShift Container Platform 4.6.20. See the following advisory for the RPM packages for this release:

Space precludes documenting all of the container images in this advisory. See the following Release Notes documentation, which will be updated shortly for this release, for details about these changes:

This update fixes the following bugs among others:

  • Previously, when importing a private image container with secrets, the image download would fail and return ErrImagePull and ImagePullBackOff errors. Consequently, the pod could not start and DeploymentConfig was stuck until ServiceAccount or DeploymentConfig was updated manually. With this update, new deployments use the internal container registry to start. As a result, importing a container image from an external private container registry now works as intended. (BZ#1926340)

  • This update supports backporting the SAPConfig gathering enhancement, since many SAP clusters are running OpenShift Container Platform 4.6. (BZ#1922855)

  • Previously, the pruner was trying detect the registry name using image streams. When there were no image streams, the pruner failed to detect the registry name. With this update, the Image Registry Operator provides the pruner with the registry name, which results in the pruner no longer depending on the existence of image streams. (BZ#1923993)

  • Previously, if the hostname from the vSphere metadata was not set before the NetworkManager started, the vSphere metadata would be ignored. This update now sets the hostname as vsphere-hostname.service before the NetworkManager starts, so long as this information is available within the vSphere metadata. (BZ#1904825)

  • Previously, the httpClient() chart repository did not consider any proxy environment variable, and thus no helm charts were displayed in the Developer Catalog. This update ensures that proxy environment variables are considered by providing a http.ProxyFromEnvironment function to the Transport struct's initialization. (BZ#1919138)

  • Previously, if the lib-bucket-provisioner service account was missing, then the creation of lib-bucket-provisioner InstallPlan overloaded the etcd and impacted the performance of the OCP Cluster. This update implements the Service Account Gatherer to the Insights Operator to collect field managementState of OpenShift Operators, which is anonymized and stored at the Insights Operator archive report. (BZ#1885941)

You may download the oc tool and use it to inspect release image metadata as follows:

(For x86_64 architecture)

$ oc adm release info quay.io/openshift-release-dev/ocp-release:4.6.20-x86_64

The image digest is sha256:ac5bbe391f9f5db07b8a710cfda1aee80f6eb3bf37a3c44a5b89763957d8d5ad

(For s390x architecture)

$ oc adm release info quay.io/openshift-release-dev/ocp-release:4.6.20-s390x

(For ppc64le architecture)

$ oc adm release info quay.io/openshift-release-dev/ocp-release:4.6.20-ppc64le
