linkwarden cannot boot: manifest DATABASE_URL points at localhost:5432 with no Postgres -- add the companion service on a FRESH branch cut from origin/dev (supersedes tsk-2hoir5) - #3110
Conversation
…ifest
Linkwarden's manifest shipped DATABASE_URL pointing at localhost:5432, but
nothing in the manifest starts a Postgres. The rendered compose file had
exactly one service (linkwarden), so the app came up pointing at a database
that did not exist.
This change adds a companion postgres service to the manifest and teaches
DockerInstaller._generate_compose to render companion services alongside
the main app service. The postgres data volume is persisted via a named
volume, and {secret_key} substitution is applied to companion env values
so POSTGRES_PASSWORD reuses the same per-app secret as NEXTAUTH_SECRET.
dev's #2837 behaviour is preserved intact: DATABASE_URL handling and the
0600 permissions on generated compose/config files remain unchanged.

Keep the PostgreSQL password stable across reinstalls.
If .secret_key is missing or malformed, _get_or_create_secret_key() generates a new value. Compose then uses it for both Linkwarden’s DATABASE_URL and PostgreSQL’s POSTGRES_PASSWORD. With the existing pgdata volume, PostgreSQL retains the old role password because the environment variable applies only during initialization. Linkwarden can therefore lose database access.
Persist this database credential without silent regeneration, or rotate the PostgreSQL role password before updating DATABASE_URL.

CARD TITLE (intent, not commit subject): linkwarden cannot boot: manifest DATABASE_URL points at localhost:5432 with no Postgres -- add the companion service on a FRESH branch cut from origin/dev (supersedes tsk-2hoir5)
Autonomous build of board card tsk-lwgxtx.
fix(linkwarden): add companion postgres service to docker compose manifest
Linkwarden's manifest shipped DATABASE_URL pointing at localhost:5432, but
nothing in the manifest starts a Postgres. The rendered compose file had
exactly one service (linkwarden), so the app came up pointing at a database
that did not exist.
This change adds a companion postgres service to the manifest and teaches
DockerInstaller._generate_compose to render companion services alongside
the main app service. The postgres data volume is persisted via a named
volume, and {secret_key} substitution is applied to companion env values
so POSTGRES_PASSWORD reuses the same per-app secret as NEXTAUTH_SECRET.
dev's #2837 behaviour is preserved intact: DATABASE_URL handling and the
0600 permissions on generated compose/config files remain unchanged.
