Images

Each subdirectory corresponds to an image that is automatically built and pushed to gcr.io/k8s-testimages when PRs that touch them merge using postsubmit prowjobs that run the image-builder

Testing Images

There is no automated testing pipeline for images:

• Any jobs that use the :latest tag use the latest published image immediately
• Any jobs that use a :v{date}-{sha}[-{variant}] tag (e.g. :v20200407-c818676-master) are updated to use the latest published image ~daily. This is accomplished by PR's created by the autobumper prowjob, which are merged by test-infra oncall once a day during weekdays.

1. Merge a PR changing something in the image directory.

2. Grep the prowjob configs to find out which jobs are using gcr.io/k8s-testimages/<image-name>:latest and monitor TestGrid for new failures corresponding to your change.

   • On failure, send a new PR to rollback your last one or a fix if you know immediately.
   • Some of these images might be presubmits; you could monitor them at http://prow.k8s.io

3. You are done. If more breaks happen later, test-infra oncall will take care of it.
