RHBA-2019:2987 - Bug Fix Advisory

Topic

Red Hat OpenShift Container Platform release 3.10.175 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 RPM packages for Red Hat OpenShift Container
Platform 3.10.z. See the following advisory for the container images for
this release:

https://access.redhat.com/errata/RHBA-2019:2988

This update includes the following bugs:

• Retrieval of image names for stage registry would result in certificate errors. A configuration option has been added that allows users to skip SSL verification. If `skip_verify_tls` is `true`, the TLS certificate of the remost registry will not be verified and no error will be present. The default setting is `false`. (BZ#1696113)
• The service-signer would be deleted when performing the redeploy-certificates playbook. As a result, internal applications that depended on a service signer certificate would need to be regenerated or would be rendered invalid. Now, the service-signer has been removed from the list of certificates to be removed during a normal non-CA certificate redeployment. Service-signer is only updated when the OpenShift CA has been renewed. (BZ#1721336)
• When using `oc replace --force`, dependent objects were not being properly removed/updated. Deployment rollouts would not complete and would be canceled. The options `--cascade` and `--grace-period` are added to the module using `oc replace`. Deployments are now properly rolled out when using `oc replace`. (BZ#1745027)
• A kernel version check has been added to ensure the installed kernel meets the required minimum to avoid network issues. This check is run during prerequisites, scaleup, and upgrade. (BZ#1749028)

All OpenShift Container Platform 3.10 users are advised to upgrade to these
updated packages and images.
