      - Builds and pushes the image to Control Plane
      - Automatically assigns image numbers, e.g., `app:1`, `app:2`, etc.
      - Uses `.controlplane/Dockerfile` or a different Dockerfile specified through `dockerfile` in the `.controlplane/controlplane.yml` file
      - If a commit is provided through `--commit` or `-c`, it will be set as the runtime env var `GIT_COMMIT`
      - Accepts extra options that are passed to `docker build`
