Prow Job Images

This directory contains custom Docker images used by our Prow jobs.

Building and publishing a new image

To build and push a new image, you can run make push from an image directory. This should only be done once a PR is approved and from the default branch.

Users typically keep their working directory at the repo root and run relative make commands, like make -C images/prow-tests push, but for brevity's sake this document just mentions the short way.

For testing purposes, you can build with --no-cache, which does not rerun a step in the Dockerfile if the text in the Dockerfile does not change (which, note, if you are doing go install or similar, and you update files, the image will not change! Either make build to rebuild everything or add/remove a no-op flag to the command you care about). Do this by running make iterative-build. Run make iterative-shell to get a shell in this image.

Note that you must have proper permission in the knative-tests project to push new images to the GCR.
