Thelounge (a fork of shoutIRC) is a web IRC client that you host on your own server.

Supported Architectures

We utilise the docker manifest for multi-platform awareness. More information is available from docker here and our announcement here.
Simply pulling 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:
amd64-<version tag>
arm64v8-<version tag>

Version Tags

This image provides various versions that are available via tags. Please read the descriptions carefully and exercise caution when using unstable or development tags.
Stable releases.
Next Pre-Releases.
Nightly images from commits in master.
## Application Setup
  • When the application first runs, it will populate its /config
  • Stop the container
  • Now from the host, edit /config/config.js, wherever you've mapped it
  • In most cases you want the value public: false to allow named users only
  • Setting the two prefetch values to true improves usability, but uses more storage
  • Once you have the configuration you want, save it and start the container again
  • For each user, run the command
  • docker exec -it thelounge s6-setuidgid abc thelounge add <user>
  • You will be prompted to enter a password that will not be echoed.
  • Saving logs to disk is the default, this consumes more space but allows scrollback.
  • To log in to the application, browse to http://<hostip>:9000
  • You should now be prompted for a username and password on the webinterface.
  • Once logged in, you can add an IRC network. Some defaults are preset for Freenode


To help you get started creating a container from this image you can either use docker-compose or the docker cli.
version: "2.1"
container_name: thelounge
- PUID=1000
- PGID=1000
- TZ=Etc/UTC
- </path/to/appdata/config>:/config
- 9000:9000
restart: unless-stopped
docker run -d \
--name=thelounge \
-e PUID=1000 \
-e PGID=1000 \
-e TZ=Etc/UTC \
-p 9000:9000 \
-v </path/to/appdata/config>:/config \
--restart unless-stopped \


Docker images 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.

for GroupID - see below for explanation

Miscellaneous Options

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__PASSWORD=/run/secrets/mysecretpassword
Will set the environment variable PASSWORD based on the contents of the /run/secrets/mysecretpassword 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.

User / Group Identifiers

When using volumes (-v flags), permissions issues can arise between the host OS and the container, we avoid this issue by allowing you to specify the user PUID and group PGID.
Ensure any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic.
In this instance PUID=1000 and PGID=1000, to find yours use id user as below:
$ id username
uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup)

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 thelounge /bin/bash
  • To monitor the logs of the container in realtime:
    • docker logs -f thelounge
  • Container version number
    • docker inspect -f '{{ index .Config.Labels "build_version" }}' thelounge
  • Image version number
    • docker inspect -f '{{ index .Config.Labels "build_version" }}'
