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.

• 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)
