Duplicate Undercloud Host entry During Stack Update

Solution In Progress - Updated -

Issue

  • We have one DCN multi stack and whenever we are adding/updating the stack then the duplicate entry of undercloud ctlplane is appending in the /etc/hosts file on undercloud node.

  • Here is an example of the /etc/hosts file:
