"""Template ``files:`` rendering: absolute container paths are bind-mounted,

Regression test: a relative ``path: Dockerfile`` used to produce the invalid

volume spec ``./Dockerfile:Dockerfile`` and every compose-based install of

such a template failed at ``docker compose up`` with "invalid mount config
