rules_docker Demonstration

Purpose

Demonstrates problems building with a Java container with rules_docker.

Preparations

Running

With RULES_DOCKER_VERSION = "0.23.0" in WORKSPACE run

bazel build --toolchain_resolution_debug=@bazel_tools//tools/cpp:toolchain_type \
  //src/main/java/com/example/hello_world:hello_world_image

On macOS we get the following result:

It works on Linux, since target and host are the same platform:
