Description of the problem / feature request:

When a sh_binary has a target in the data attribute, the target is not built automatically when the sh_binary target is built.

Bugs: what's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

• Check out rules_docker
• bazel clean
• bazel build //docs:update
