Limnoria A robust, full-featured, and user/programmer-friendly Python IRC bot, with many existing plugins. Successor of the well-known Supybot.

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>

Application Setup

New Configuration

If you do not have an existing config you will need to start the container and then run the following wizard command:
docker exec -it -w /config -u abc limnoria limnoria-wizard

Existing Configuration

If you have an existing config, adjust the directory settings in your conf file as follows:
supybot.directories.backup: /config/backup
supybot.directories.conf: /config/conf /config/data /config/data/tmp /config/web
supybot.directories.log: /config/logs
supybot.directories.plugins: /config/plugins
NOTE: These are not grouped together in the file. You will need to search your conf file for the variables.
Then place your conf file and any of your existing directories in /config and start up the container.

Plugin Requirements

The container will pip install any requirements.txt it finds in the /config/plugins folder on startup.
If you install a plugin using the PluginDownloader that includes a requirements.txt you can execute a shell into the container and then use pip install /config/plugins/ThePlugin/requirements.txt or restart the container and the requirements will be installed.


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: limnoria
- PUID=1000
- PGID=1000
- TZ=Etc/UTC
- path/to/config:/config
- 8080:8080
restart: unless-stopped
docker run -d \
--name=limnoria \
-e PUID=1000 \
-e PGID=1000 \
-e TZ=Etc/UTC \
-p 8080:8080 \
-v path/to/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.

Ports (-p)

Port for Limnoria's web interface.

Environment Variables (-e)

for UserID - see below for explanation
for GroupID - see below for explanation
specify a timezone to use, see this list.

Volume Mappings (-v)

Where Limnoria config is stored.

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.
