sneak 9cd50acd85 Add docker-compose.yml for deploying upaas (closes #223)
Check / check (pull_request) Skipped
The compose file builds the image from this repo, mounts the Docker
socket and HOST_DATA_DIR (passed to upaas as UPAAS_HOST_DATA_DIR),
reads settings from .env, and restarts unless stopped. The port is
published on 127.0.0.1 only, for a TLS-terminating proxy in front.
PORT and UPAAS_DATA_DIR are pinned so .env cannot move upaas off the
port mapping, the healthcheck (busybox wget) or the data mount.

upaas now refuses to start when UPAAS_HOST_DATA_DIR is set to a
relative path; when unset it still falls back to the data directory.

The README's plain-HTTP Compose example becomes a short deploy section
that points at the file. .env is added to .dockerignore.

# Completed Steps
- 2026-09-29: An image built from the `Dockerfile` now shows the commit it was
built from (the `git describe` output) in the footer and `/health` instead of
`dev`: `.dockerignore` no longer leaves out `.git`, nor any tracked file,
which git would count as deleted and mark `-dirty`. upaas now also logs its
version at startup; the logger's `Identify()` was never called (#236).
- 2026-09-29: The app page shows the app's branch as a label in its title, next
to the status badge, instead of after the repository under it (#240).
- 2026-09-29: An app's deployments page now lists only its 10 most recent
deployments, newest first, instead of 50 (#238).
- 2026-09-29: `docker-compose.yml` now sets `UPAAS_PORT` to 8080 as well as
`PORT`, since upaas reads `UPAAS_PORT` first and a `UPAAS_PORT` in `.env` made
it listen away from the port mapping and healthcheck; the README's Compose
section names both (#230).
- 2026-09-29: The README Configuration table now lists every setting upaas
reads, adding `UPAAS_MAINTENANCE_MODE`, `UPAAS_SESSION_SECRET` and
`UPAAS_CORS_ORIGINS`, and gives the real default and effect of each:
`UPAAS_PORT` wins over `PORT`, `UPAAS_HOST_DATA_DIR` falls back to
`UPAAS_DATA_DIR`, `UPAAS_DEBUG` drops the session cookie's `Secure` flag, and
`UPAAS_SENTRY_DSN` is not used (#229).
- 2026-09-28: The README Configuration table now names `UPAAS_DEBUG`,
`UPAAS_SENTRY_DSN`, `UPAAS_METRICS_USERNAME` and `UPAAS_METRICS_PASSWORD`, the
names upaas actually reads (the unprefixed names it listed were ignored), and
the `UPAAS_HOST_DATA_DIR` row refers to `UPAAS_DATA_DIR` (#224).
- 2026-09-28: Added `docker-compose.yml` for deploying upaas: settings from
`.env`, the port published on `127.0.0.1` only for a TLS proxy in front, and a
healthcheck against `/health`; the README's plain-HTTP Compose example is
