Bazel

This tasks builds source into a container image using the Bazel build tool, and Bazel's container image support.

This assumes the source repo in question is using the container_push rule to build and push a container image. For example:

container_push(
  name = "push",
  format = "Docker", # Or "OCI"
  image = ":image",
  registry = "gcr.io",
  repository = "my-project/my-app",
  stamp = True,
)

This target instructs Bazel to build and push a container image containing the application defined by the :image target, based on a suitable base image.

The rules_docker repo defines build rules to construct images for a variety of popular programming languages, like Python, Java, Go and many more.
