+++ This bug was initially created as a clone of Bug #1797133 +++ Description of problem: For example passing --ipaddrs=[::1] would currently fail as this is not a valid IPv6 address. The reason we want this ability is to simplify IPv6 validation as we do not need to worry about changing the format of the address before passing it to the agent. If the underlying IPv6 address is valid kube-client-agent will do the right thing and handle unescaping for free. Version-Release number of selected component (if applicable): How reproducible: always Steps to Reproduce: 1. pass escaped ipv6 address to certagent 2. 3. Actual results: failure Expected results: address is handled Additional info:
