      * Previously for hosted control planes (HCP), a cluster that used mirroring release images might result in existing node pools to use the hosted cluster's operating system version instead of the `NodePool` version. With this release, a fix ensures that node pools use their own versions. (link:https://issues.redhat.com/browse/OCPBUGS-42881[*OCPBUGS-42881*])

      Description of problem:

      ROSA HCP allows customers to select hostedcluster and nodepool OCP z-stream versions, respecting version skew requirements. E.g.:

      • A 4.15.28 hostedcluster with
      • A 4.15.28 nodepool
      • A 4.15.25 nodepool

      Version-Release number of selected component (if applicable):

      Reproducible on 4.14-4.16.z, this bug report demonstrates it for a 4.15.28 hostedcluster with a 4.15.25 nodepool

      How reproducible:

      100%

      Steps to Reproduce:

          1. Create a ROSA HCP cluster, which comes with a 2-replica nodepool with the same z-stream version (4.15.28)
    2. Create an additional nodepool at a different version (4.15.25)

      Actual results:

      Observe that while nodepool objects report the different version (4.15.25), the resulting kernel version of the node is that of the hostedcluster (4.15.28)
