# Public VPS (asgard) deployment — hardened, single-host, behind Caddy.
|
||
|
|
#
|
||
|
|
# Differs from docker-compose.server.yml (the home/LXC stack): the database is NEVER
|
||
|
|
# published, the app binds to 127.0.0.1 only (Caddy terminates TLS and reverse-proxies it),
|
||
|
|
# there is no apparmor:unconfined (this is a bare VPS, not Docker-in-LXC), and every service
|
||
|
|
# has a hard memory/CPU cap so the stack can't exhaust the small VPS.
|
||
|
|
#
|
||
|
|
# Secrets live OUTSIDE the repo, in an env file on the host. Deploy with:
|
||
|
|
# docker compose -f docker-compose.prod.yml --env-file /srv/subfeed/.env up -d --build
|
||
|
|
#
|
||
|
|
# Required keys in that env file: POSTGRES_PASSWORD, SECRET_KEY (>=32 chars),
|
||
|
|
# TOKEN_ENCRYPTION_KEY (Fernet), GOOGLE_CLIENT_ID, GOOGLE_CLIENT_SECRET,
|
||
|
|
# OAUTH_REDIRECT_URL=https://subfeed.b1fr0st.eu/auth/callback, ALLOWED_EMAILS, ADMIN_EMAILS.
