linuxserver/quassel-core¶
Quassel-core is a modern, cross-platform, distributed IRC client, meaning that one (or multiple) client(s) can attach to and detach from a central core.
This container handles the IRC connection (quasselcore) and requires a desktop client (quasselclient) to be used and configured. It is designed to be always on and will keep your identity present in IRC even when your clients cannot be online. Backlog (history) is downloaded by your client upon reconnection allowing infinite scrollback through time.
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/quassel-core: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¶
Quassel wiki: quassel
A great place to host a quassel instance is a VPS, such as DigitalOcean. For $5 a month you can have a 24/7 IRC connection and be up and running in under 55 seconds (or so they claim).
Once you have the container running, fire up a quassel desktop client and connect to your new core instance using your droplets public IP address and the port you specified in your docker run
command default: 4242. Create an admin user, select SQLite as your storage backend (Quassel limitation). Setup your real name and nick, then press Save & Connect
.
You're now connected to IRC. Let's add you to our IRC #linuxserver.io
room on Freenode. Click 'File' > 'Networks' > 'Configure Networks' > 'Add' (under Networks section, not Servers) > 'Use preset' > Select 'Freenode' and then configure your identity using the tabs in the 'Network details' section. Once connected to Freenode, click #join
and enter #linuxserver.io
. That's it, you're done.
Stateless usage¶
To use Quassel in stateless mode, where it needs to be configured through environment arguments, run it with the --config-from-environment
RUN_OPTS environment setting.
Env | Usage |
---|---|
DB_BACKEND | SQLite or PostgreSQL |
DB_PGSQL_USERNAME | PostgreSQL User |
DB_PGSQL_PASSWORD | PostgreSQL Password |
DB_PGSQL_HOSTNAME | PostgreSQL Host |
DB_PGSQL_PORT | PostgreSQL Port |
AUTH_AUTHENTICATOR | Database or LDAP |
AUTH_LDAP_HOSTNAME | LDAP Host |
AUTH_LDAP_PORT | LDAP Port |
AUTH_LDAP_BIND_DN | LDAP Bind Domain |
AUTH_LDAP_BIND_PASSWORD | LDAP Password |
AUTH_LDAP_FILTER | LDAP Authentication Filters |
AUTH_LDAP_UID_ATTRIBUTE | LDAP UID |
Additionally you have RUN_OPTS that can be used to customize pathing and behavior.
Option | Example |
---|---|
--strict-ident | strictly bool --strict-ident |
--ident-daemon | strictly bool --ident-daemon |
--ident-port | --ident-port "10113" |
--ident-listen | --ident-listen "::,0.0.0.0" |
--ssl-cert | --ssl-cert /config/keys/cert.crt |
--ssl-key | --ssl-key /config/keys/cert.key |
--require-ssl | strictly bool --require-ssl |
Minimal example with SQLite:
docker create \
--name=quassel-core \
-e PUID=1000 \
-e PGID=1000 \
-e TZ=Europe/London \
-e RUN_OPTS='--config-from-environment' \
-e DB_BACKEND=SQLite \
-e AUTH_AUTHENTICATOR=Database \
-p 4242:4242 \
-v <path to data>:/config \
--restart unless-stopped \
linuxserver/quassel-core
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:
quassel-core:
image: lscr.io/linuxserver/quassel-core:latest
container_name: quassel-core
environment:
- PUID=1000
- PGID=1000
- TZ=Etc/UTC
- RUN_OPTS=--config-from-environment #optional
volumes:
- /path/to/quassel-core/data:/config
ports:
- 4242:4242
- 113:10113 #optional
restart: unless-stopped
docker cli (click here for more info)¶
docker run -d \
--name=quassel-core \
-e PUID=1000 \
-e PGID=1000 \
-e TZ=Etc/UTC \
-e RUN_OPTS=--config-from-environment `#optional` \
-p 4242:4242 \
-p 113:10113 `#optional` \
-v /path/to/quassel-core/data:/config \
--restart unless-stopped \
lscr.io/linuxserver/quassel-core: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 |
---|---|
4242 | The port quassel-core listens for connections on. |
10113 | Optional Ident Port |
Environment Variables (-e
)¶
Env | Function |
---|---|
PUID=1000 | for UserID - see below for explanation |
PGID=1000 | for GroupID - see below for explanation |
TZ=Etc/UTC | specify a timezone to use, see this list. |
RUN_OPTS=--config-from-environment | Custom CLI options for Quassel |
Volume Mappings (-v
)¶
Volume | Function |
---|---|
/config | Database and quassel-core configuration storage. |
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:
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.
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 your_user
as below:
Example output:

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:
-
Single image:
-
-
Update containers:
-
All containers:
-
Single container:
-
-
You can also remove the old dangling images:
Via Docker Run¶
-
Update the image:
-
Stop the running container:
-
Delete the container:
-
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:
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-quassel-core.git
cd docker-quassel-core
docker build \
--no-cache \
--pull \
-t lscr.io/linuxserver/quassel-core:latest .
The ARM variants can be built on x86_64 hardware using multiarch/qemu-user-static
Once registered you can define the dockerfile to use with -f Dockerfile.aarch64
.
