Buildah

This Task builds source into a container image using Project Atomic's Buildah build tool. It uses Buildah's support for building from Dockerfiles, using its buildah bud command. This command executes the directives in the Dockerfile to assemble a container image, then pushes that image to a container registry.

Install the Task

kubectl apply -f https://raw.githubusercontent.com/tektoncd/catalog/v1beta1/buildah/buildah.yaml

Parameters

• IMAGE: The name (reference) of the image to build.
• BUILDER_IMAGE:: The name of the image containing the Buildah tool. See note below. (default: quay.io/buildah/stable:v1.11.0)
• DOCKERFILE: The path to the Dockerfile to execute (default: ./Dockerfile)
• CONTEXT: Path to the directory to use as context (default: .)
• TLSVERIFY: Verify the TLS on the registry endpoint (for push/pull to a non-TLS registry) (default: true)
• FORMAT: The format of the built container, oci or docker (default: oci)

Workspaces

• source: A git-type PipelineResource specifying the location of the source to build.
