Merge pull request #45447 from gyliu513/init-container
Automatic merge from submit-queue Put initContainers to PodSpec for some statefulset examples. **What this PR does / why we need it**: Fixed https://github.com/kubernetes/kubernetes/issues/45405 The `init container` is [graduated to GA](https://github.com/kubernetes/kubernetes/pull/38382) , so some test YAML templates needs to be updated to not use `annotations`. The following are the two places that needs update: 1. [cockroachdb](https://github.com/kubernetes/kubernetes/blob/master/examples/cockroachdb/cockroachdb-statefulset.yaml) 2. [e2e statefulset test](https://github.com/kubernetes/kubernetes/tree/master/test/e2e/testing-manifests/statefulset) **Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes # **Special notes for your reviewer**: **Release note**: ```release-note ```
