# The homeserver listens on http://localhost:8008. Put a TLS-terminating
# reverse proxy in front of it before pointing a domain at it; see
# docs/deployment.md. With the observability profile, Grafana is on
# http://localhost:3000 (admin / admin, change it), Prometheus on :9090 and
# the Jaeger UI on :16686.
#
# Create the first administrator once the server is up:
#
#   docker compose exec warp warp create-account --username admin --admin
