container: support additional container images per repo - #371
Merged
Conversation
Add additional_containers template variable that renders extra jobs in container.yml and container-rebuild.yml. Each entry has a name, file (Dockerfile), and push (list of registries). Use this to add the butane container image to ignition's CI, building from Dockerfile.butane and pushing to quay.io/coreos/butane.

Summary
Add support for repos that need to build multiple container images from different Dockerfiles. This is needed for ignition, which now builds both
ignition-validateandbutanecontainers from the same repo after the Butane merge (#2235).Changes
container/container.yml-- Add a{% for %}loop overadditional_containersthat renders extra jobs, each with its own Dockerfile and push targetcontainer/container-rebuild.yml-- Same change for the rebuild workflowconfig.yaml-- Addadditional_containersto ignition's config with the butane container (Dockerfile.butane->quay.io/coreos/butane)Rendered output
Ignition's
container.ymlnow has two jobs:build-container-- buildsDockerfile.validate, pushes toquay.io/coreos/ignition-validate(unchanged)build-container-butane-- buildsDockerfile.butane, pushes toquay.io/coreos/butane(new)Other repos are unaffected (
additional_containersdefaults to an empty list).Related
