What type of PR is this?
/kind bug
What this PR does / why we need it:
This PR addresses an issue with ansible templating that results in the etcd cluster failing to be upgraded when
etcd_deployment_type == "kubeadm"
.The line above always results in
False
since ansible evaluates conversion operator|
before the comparison operator==
.This PR also adds a CI job to the periodic (nightly) run to test the upgrade with etcd managed by kubeadm so we can catch this kind of breakage in the future.
Which issue(s) this PR fixes:
Fixes #8721
