I imagine this should be ${DOCKER_HOME}/.cache/ccache?

-v "${CCACHE_DIR}:${DOCKER_HOME}/.ccache" \

Not necessarily, since ccache will honor ~/.ccache.

Wait, no, since it won't already exists.

ccache doesn't do that? That seems a little odd.

Do what? ccache will automatically create the directory, but prefer ~/.cache/ccache if ~/.ccache does not exists.

Not that it mattered in that instance, since the directory is guaranteed to exists (as a mountpoint for docker), so I could have left it at that.

I meant for consistency and to prevent future confusion, unless there was a reason to have it different.
