Are customizations supported for master and infrastructure resources in OSD or ROSA?

Solution Verified - Updated -

Environment

  • Red Hat OpenShift Dedicated (OSD)
  • Red Hat OpenShift Service on AWS (ROSA)

Issue

  • Is customization supported for master and infrastructure components in OSD or ROSA?
  • Can we customize AWS resources like security groups and ELB configurations in OSD or ROSA?

Resolution

No, any master and infrastructure resources customization is not supported in OSD and ROSA, as they are managed services, unless it's documented as supported customization.

Any unexpected manual changes to master or infrastructure resources can trigger alerts and automated rollback immediately or later timings like pod redeployed and/or cluster upgraded.

Root Cause

OSD and ROSA are managed services, and only documented customization is allowed.
