# 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: `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
