Dockarr

Dockarr is still pre-release. Use at your own risk.

Dockarr is a companion app for people running the *arr stack using docker-compose and using Prowlarr to keep Indexers in sync.

Dockarr automatically discovers your "*arr" services and adds them to the discovered Prowlarr instance as applications. It runs in an infite loop to apply the future changes.

It also adds the discovered download clients to discovered *arr services.

By default, Dockarr uses your docker container name as the hostname, extracts the service apiKey, urlBase, protocol and the port from the config.xml file.

It currently supports:

Arr* services:

• Radarr
• Sonarr
• Lidarr
• Readarr

Download clients:

• Transmission

Coming later:

• Other *arr services: LazyLibrarian, Mylar, Whisparr etc.
• Download clients: SABnzbd etc.

Usage

1. Add dockarr to your docker-compose.yaml and mount docker socket to it.
2. Label your *arr services with discovery label: dockarr.discover
3. Profit?

dockarr:
  container_name: dockarr
  image: ghcr.io/huseyz/dockarr:latest
  volumes:
    - /var/run/docker.sock:/var/run/docker.sock

prowlarr:
  container_name: prowlarr
  image: ghcr.io/hotio/prowlarr:latest
  restart: unless-stopped
  ports:
    - 9696:9696
  labels:
    - dockarr.discover

sonarr:
  container_name: sonarr
  image: ghcr.io/hotio/sonarr:latest
  restart: unless-stopped
  ports:
    - 8989:8989
  labels:
    - dockarr.discover

Check the example docker-compose file here for a more complete example.

Configuration

Dockarr has two types of configuration support. For general config it uses environment variables. For service specific configuration, use labels.

Environment variables

Environment Variable	Description	Default	Possible Values
LOG_LEVEL	Log level for the Dockarr service.	Info	Debug, Info, Warn, Error
DELETE_BEHAVIOUR	When Dockarr does not discover an existing *arr application, this tells it what to do	Ignore	Delete, Disable, Ignore
SYNC_INTERVAL	The interval Dockarr discovers and syncs your services, in seconds.	60	Any integer

Labels

You can override certain settings per service using docker labels.

*arr Services

You can override the SyncLevel or the complete address of a service.

Label	Description
dockarr.override.address	Full address of the application, including protocol(http(s)), hostname, port and base url.
dockarr.override.syncLevel	By default Dockarr sets application-indexer sync level to fullSync. Use addOnly or disabled to override

Transmission

Label	Description
dockarr.override.host	Hostname of the transmision
dockarr.override.port	Port of the transmision
dockarr.override.ssl	Whether to use SSL for the transmision connection
dockarr.override.urlbase	RPC Url base of transmision
