Description aaleman 2021-03-17 14:16:02 UTC
Description of problem:

Openshift builds seem to poll pods, which creates load issues on the APIServer when having a large number of builds. This was a contributing factor to the build farm outage on March 11th and 12th. Instead of polling, they should use a watch, similiar to what is here: https://github.com/openshift/ci-tools/pull/1784/files#diff-9f3405a81a6f10db7c3377444f624e921a620cbfaae2df4340abe708aa9cff2cR247

Note that the polling issue here is limited to the openshift-apiserver; openshift-controller-manager does not seem to have this problem.
