Comment 3 Jon Uriarte 2020-04-28 16:05:44 UTC

Verified in 4.3.0-0.nightly-2020-04-27-081123 on top of OSP 13 2020-04-01.3 puddle.

Upgrading the OSP octavia from 13 to 16 is detected by the cno and acts accordingly,
the admission controller pods are removed as it supports double listeners with the new
octavia version and the amphora driver.

Before the upgrade:

$ oc -n openshift-kuryr get pods
