Variables - crcon.cloud

The template configures roughly 40 variables across the seven services. Almost all of them are wired together with Railway references and never need touching. This page covers the ones you might actually change, then summarizes the wiring for the curious.

Variables you set at deploy time

All three live on the backend service; the supervisor references them from there.

Variable	Meaning
`HLL_HOST`	Your game server’s IP address, without a port
`HLL_PORT`	The RCON port (not the game or query port)
`HLL_PASSWORD`	The RCON password from your provider’s panel

Changing them later: edit them on the backend, then redeploy the backend and supervisor.

Variables you might change later

Variable	Service	Meaning
`HLL_GAME`	backend	`hll` (default) or `hllv` for Hell Let Loose: Vietnam. Supervisor and frontend reference it
`DONT_SEED_ADMIN_USER`	backend	Empty seeds the default `admin` / `admin` login on first boot. Set to any value to disable seeding
`SENTRY_DSN`	backend	Optional Sentry error reporting
`DOMAINS`	backend	Django’s allowed hosts and CSRF origins. Add any custom domain you attach to the frontend, keeping the existing entries
`RCONWEB_EXTERNAL_ADDRESS`	backend, supervisor	The public address CRCON advertises. Update if you switch the frontend to a custom domain
`SESSION_COOKIE_DOMAIN`, `CSRF_COOKIE_DOMAIN`	backend	Only for multi-server single sign-on on custom subdomains; see the multi-server guide

Multi-server identity

These two make each game server’s data distinct. Rules and per-server values are covered in the multi-server guide.

Variable	Meaning
`SERVER_NUMBER`	Namespaces every database record for this game server. Never reuse across live services
`HLL_REDIS_DB`	The Redis logical database for this game server. Never reuse; match `SERVER_NUMBER`

The wiring (don’t touch)

Everything else exists to point services at each other and mirror upstream’s compose file:

Database: HLL_DB_* on the backend and supervisor reference the Postgres service’s generated credentials (POSTGRES_USER, POSTGRES_PASSWORD, POSTGRES_DB) and private domain.
Redis: HLL_REDIS_HOST, HLL_REDIS_PORT, and HLL_REDIS_URL reference the Redis service’s private domain.
Secrets: RCONWEB_API_SECRET is generated once at deploy and encrypts sessions and stored passwords. Never change it after first deploy; doing so invalidates stored credentials.
Cross-service: CRCON_API_HOST (frontend to backend), SUPERVISOR_RPC_URL (backend to supervisor), and CRCON_FRONTEND_HOST (backend’s internal alias for the UI’s multi-server registry) are all private-network references.
Ports: PORT tells Railway which port to healthcheck where a healthcheck exists; RCONWEB_PORT, PUBLIC_STATS_PORT, and PUBLIC_STATS_PORT_HTTPS are display-only on Railway.
Logging: LOGGING_LEVEL (INFO), LOGGING_PATH, and CONFIG_DIR mirror upstream defaults.
