# Self-hosting Siftlode — pulls the prebuilt image, no source build needed.
#
#   1. Run ./install.sh  (or install.ps1 on Windows) once — it generates a .env with secrets.
#   2. docker compose -f docker-compose.selfhost.yml up -d
#   3. Open the setup wizard at the URL printed in the logs:
#        docker compose -f docker-compose.selfhost.yml logs api | grep SETUP
#
# The .env only needs four values (the install script generates all of them):
#   POSTGRES_PASSWORD, SECRET_KEY, TOKEN_ENCRYPTION_KEY, OAUTH_REDIRECT_URL
# Everything else — the admin account, Google sign-in, SMTP — is set in the web wizard on
# first run. See docs/self-hosting.md.

# Bounded container logs. Docker's json-file driver keeps every line forever by default, and the API
# now writes one structured line per request — 3×50 MB per service is days of history on a
# busy instance and a hard ceiling on the disk it can take.
