Dependency

Good job! It's nice and clear.
I have a question. The docker image is built with the dependency install script. What if I modify the dependency install script, will the docker image be rebuilt or keep the same with the cached one?

Currently it uses the cache. If you fiddle with your scripts, I recommend you flush your travis-CI cache so that it forces the rebuild.

Since the dockerfile just checks a hard-named script which the user repo needs to define themselves, I haven't yet figured out a way to check for changes to that script (or to any scripts that script may call) in such a way that intelligently rebuilds it.

For now: If you are changing your scripts, flush the cache before your test.

I see. Thanks!
