CoreOS upgrades to RHEL 9. We should extra verify that DeamonSets are working after upgrade (Sysdig, vrops, etc) as they hook into the kernel.

Verify the config files we inject via Ignition are still valid, chronyd, network config, mutlipath, etc

RHCOS now includes lsof

Only 3 APIs being removed this time, and only one that matters autoscaling/v2beta2.

New flag added to run must-gather in a specified namespace With OpenShift Container Platform 4.13, the --run-namespace flag is now available for the oc adm must-gather command. You can use this flag to specify an existing namespace to run the must-gather tool in.

oooo, we can set a dedicated namespace up for that instead of it creating and deleting namespaces each time.

Updated web console behavior when disabling copied CSVs The OpenShift Container Platform web console has been updated to provide better Operator discovery when copied cluster service versions (CSVs) are disabled on a cluster.

We can try disabling CSV again in PROD

Support for setting the core user password You can now create a password for the RHCOS core user. If you cannot use SSH or the oc debug node command to access a node, this password allows you to use the core user to access the node through a cloud provider serial console or a bare metal baseboard controller manager (BMC).

We should definitely do this.

New option to filter node-related dashboards by node role In the OpenShift Container Platform web console, you can now filter data in node-related monitoring dashboards based on node roles. You can use this new filter to quickly select relevant node roles if you want to see dashboard data only for nodes with certain roles, such as worker nodes.

Looking forward to this

Toolbox is deprecated in RHCOS The toolbox script is deprecated and support will be removed from a future OpenShift Container Platform release.

Will need to check with RH what the replacement is
