      *Cause*: Mixing upper and lower case in the host name makes MicroShift crash.
      *Consequence*: node name was taken straight from host name, and kubernetes does not allow upper case names.
      *Fix*: Transform the name to use only lower case.
      *Result*: Bug doesn’t present anymore.

    Description

      Description of problem:

      Install RHEL with Microshift image and configure a Hostname which has an uppercase letter e.g: Microshift.local. 
After the node restarts, Microshift does not come up and all pods remain in pending state.

       

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

      4.12.5

      How reproducible:

      Install RHEL 8.7 with Microshift 4.12.5 and set Hostname with Upper Case letter

      Steps to Reproduce:

      1. Install RHEL with Upper case hostname
2. Restart the node.
3. Microshift is not ready.

      Actual results:

      Microshift Cluster does not come up.

      Expected results:

      Microshift cluster should come up without any issues

      Additional info:

      Changing the host name back to lower case does not help, need to reinstall OS with new Hostname containing all lower case.

          Bug - A problem that impairs or prevents the functions of the product. OCPBUGS-8493 Microshift does not come up if the Hostname of RHEL has an upper case letter

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
