Images used for various CI jobs for cert-manager and related projects.
All images are built in Prow. There is a Prow job per image in config/jobs/testing/test-trusted.yaml.
Most images are built using the scripts in images/builder.
images/kind contains a script to build our own kind image—this may be useful when needing to test against a particular version of Kubernetes for which there is no 'official' kind image yet.
To build for a new Kubernetes version, change the KUBERNETES_VERSION variable in images/kind/build.sh—this should trigger the post-testing-push-kind Prow job and a gcr.io/jetstack-build-infra-images/kind:<KUBERNETES_VERSION> image should get built and pushed.
This image build does not use images/builder functionality because the image is built with kind, not Docker.
