RHBA-2018:0600 - Bug Fix Advisory

Topic

Updated atomic-openshift-utils and openshift-ansible packages that fix a bug are now available for OpenShift Container Platform 3.9.

Description

Red Hat OpenShift Container Platform is the company's cloud computing Platform-as-a-Service (PaaS) solution designed for on-premise or private cloud deployments.

The atomic-openshift-utils and openshift-ansible packages contain the installation utility and Ansible requirements for installing and upgrading OpenShift Container Platform 3.

This advisory contains the RPM packages for this release. See the following
advisory for the container image for this release:

https://access.redhat.com/errata/RHBA-2018:0601

This update fixes the following bug:

• The node scale-up and installation Ansible playbooks may have consumed more memory on the control host (the system where you run the playbooks from) than expected due to the use of `include_tasks` in several places. The majority of these instances have now been converted to `import_tasks` calls, which do not consume as much memory. After this change, memory consumption on the control host should be below 100MiB per host; for large environments (100+ hosts), a control host with at least 16GiB of memory is recommended. (BZ#1558672)

All OpenShift Container Platform 3.9 users are advised to upgrade to these updated packages.

Solution

Before applying this update, make sure all previously released errata relevant to your system have been applied.

To apply this update, run the following on all hosts where you intend to initiate Ansible-based installation or upgrade procedures:

# yum update atomic-openshift-utils
