Environment variables

This reference lists container-level environment variables that DUMB reads at startup. Service-specific environment variables are set in dumb_config.json under each service’s env block.

Container variables

Variable Default Description
PUID 1000 Container user ID
PGID 1000 Container group ID
TZ unset Time zone (for example America/New_York)

Persist your config

These values are typically set in your docker-compose.yml or .env file so they survive container restarts.

Service environment variables

Each service can define environment variables under its env block in dumb_config.json. DUMB merges these with defaults when it performs service setup.

Example:

"nzbdav": {
  "env": {
    "WEBDAV_USER": "admin",
    "WEBDAV_PASSWORD": "change-me"
  }
}

Secrets in config files

Treat tokens and passwords in dumb_config.json as secrets. Avoid committing them to source control.
