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:

https://access.redhat.com/errata/RHBA-2020:0673

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:

https://docs.openshift.com/container-platform/4.6/release_notes/ocp-4-6-release-notes.html

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:
