linuxserver/synclounge ¶

Synclounge is a third party tool that allows you to watch Plex in sync with your friends/family, wherever you are.

Supported Architectures¶

We utilise the docker manifest for multi-platform awareness. More information is available from docker here and our announcement here.

Simply pulling lscr.io/linuxserver/synclounge:latest should retrieve the correct image for your arch, but you can also pull specific arch images via tags.

The architectures supported by this image are:

Architecture	Available	Tag
x86-64	✅	amd64-<version tag>
arm64	✅	arm64v8-<version tag>
armhf	❌

Application Setup¶

The web app and the server are both accessible at http://SERVERIP:8088.

Note: It is recommended to use http as the external proto with a reverse proxy due to https not working with external plex clients.

Usage¶

To help you get started creating a container from this image you can either use docker-compose or the docker cli.

docker-compose (recommended, click here for more info)¶

---
services:
  synclounge:
    image: lscr.io/linuxserver/synclounge:latest
    container_name: synclounge
    environment:
      - AUTH_LIST=plexuser1,plexuser2,email1,machineid1 #optional
    ports:
      - 8088:8088
    restart: unless-stopped

docker cli (click here for more info)¶

docker run -d \
  --name=synclounge \
  -e AUTH_LIST=plexuser1,plexuser2,email1,machineid1 `#optional` \
  -p 8088:8088 \
  --restart unless-stopped \
  lscr.io/linuxserver/synclounge:latest

Parameters¶

Containers are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate <external>:<internal> respectively. For example, -p 8080:80 would expose port 80 from inside the container to be accessible from the host's IP on port 8080 outside the container.

Ports (`-p`)¶

Parameter	Function
`8088`	Web app and server port

Environment Variables (`-e`)¶

Env	Function
`AUTH_LIST=plexuser1,plexuser2,email1,machineid1`	If set, only the users defined here and the users of the plex servers defined here will be able to access the server. Use e-mails, plex usernames and/or plex server machine ids, comma separated, no spaces.

Volume Mappings (`-v`)¶

Volume	Function

Miscellaneous Options¶

Parameter	Function

Environment variables from files (Docker secrets)¶

You can set any environment variable from a file by using a special prepend FILE__.

As an example:

-e FILE__MYVAR=/run/secrets/mysecretvariable

Will set the environment variable MYVAR based on the contents of the /run/secrets/mysecretvariable file.

Umask for running applications¶

For all of our images we provide the ability to override the default umask settings for services started within the containers using the optional -e UMASK=022 setting. Keep in mind umask is not chmod it subtracts from permissions based on it's value it does not add. Please read up here before asking for support.

Docker Mods¶

We publish various Docker Mods to enable additional functionality within the containers. The list of Mods available for this image (if any) as well as universal mods that can be applied to any one of our images can be accessed via the dynamic badges above.

Support Info¶

Shell access whilst the container is running:
```
docker exec -it synclounge /bin/bash
```
To monitor the logs of the container in realtime:
```
docker logs -f synclounge
```

Container version number:

docker inspect -f '{{ index .Config.Labels "build_version" }}' synclounge

Image version number:

docker inspect -f '{{ index .Config.Labels "build_version" }}' lscr.io/linuxserver/synclounge:latest

Updating Info¶

Most of our images are static, versioned, and require an image update and container recreation to update the app inside. With some exceptions (noted in the relevant readme.md), we do not recommend or support updating apps inside the container. Please consult the Application Setup section above to see if it is recommended for the image.

Below are the instructions for updating containers:

Via Docker Compose¶

Update images:

All images:
```
docker-compose pull
```
Single image:
```
docker-compose pull synclounge
```

Update containers:

All containers:
```
docker-compose up -d
```
Single container:
```
docker-compose up -d synclounge
```

You can also remove the old dangling images:
```
docker image prune
```

Via Docker Run¶

Update the image:

docker pull lscr.io/linuxserver/synclounge:latest

Stop the running container:
```
docker stop synclounge
```
Delete the container:
```
docker rm synclounge
```
Recreate a new container with the same docker run parameters as instructed above (if mapped correctly to a host folder, your /config folder and settings will be preserved)
You can also remove the old dangling images:
```
docker image prune
```

Image Update Notifications - Diun (Docker Image Update Notifier)¶

Tip

We recommend Diun for update notifications. Other tools that automatically update containers unattended are not recommended or supported.

Building locally¶

If you want to make local modifications to these images for development purposes or just to customize the logic:

git clone https://github.com/linuxserver/docker-synclounge.git
cd docker-synclounge
docker build \
  --no-cache \
  --pull \
  -t lscr.io/linuxserver/synclounge:latest .

The ARM variants can be built on x86_64 hardware using multiarch/qemu-user-static

docker run --rm --privileged multiarch/qemu-user-static:register --reset

Once registered you can define the dockerfile to use with -f Dockerfile.aarch64.

Versions¶
