quassel-core
Container
Quassel IRC is a modern, cross-platform, distributed IRC client, meaning that one (or multiple) client(s) can attach to and detach from a central core -- much like the popular combination of screen and a text-based IRC client such as WeeChat, but graphical. Blowfish support and optional web-ui included.

DEPRECATION NOTICE
This image is deprecated. We will not offer support for this image and it will not be updated.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-\ |
| arm64 | ✅ | arm64v8-\ |
| armhf | ❌ |
Application Setup
Quassel wiki: quasselA 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 RUNOPTS environment setting.| Env | Usage |
|---|---|
| DBBACKEND | SQLite or PostgreSQL |
| DBPGSQLUSERNAME | PostgreSQL User |
| DBPGSQLPASSWORD | PostgreSQL Password |
| DBPGSQLHOSTNAME | PostgreSQL Host |
| DBPGSQLPORT | PostgreSQL Port |
| AUTHAUTHENTICATOR | Database or LDAP |
| AUTHLDAPHOSTNAME | LDAP Host |
| AUTHLDAPPORT | LDAP Port |
| AUTHLDAPBINDDN | LDAP Bind Domain |
| AUTHLDAPBINDPASSWORD | LDAP Password |
| AUTHLDAPFILTER | LDAP Authentication Filters |
| AUTHLDAPUIDATTRIBUTE | LDAP UID |
Additionally you have RUNOPTS 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' \

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.| Parameter | Function |
|---|---|
-p 4242:4242 | The port quassel-core listens for connections on. |
-p 10113 | Optional Ident Port |
-e PUID=1000 | for UserID - see below for explanation |
-e PGID=1000 | for GroupID - see below for explanation |
-e TZ=Etc/UTC | specify a timezone to use, see this list. |
-e RUNOPTS=--config-from-environment | Custom CLI options for Quassel |
-v /config | Database and quassel-core configuration storage. |
Environment variables from files (Docker secrets)
You can set any environment variable from a file by using a special prependFILE__.As an example:
-e FILE__MYVAR=/run/secrets/mysecretvariableWill 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:id your_userExample output:
uid=1000(your_user) gid=1000(your_user) groups=1000(your_user)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:
```bash
docker exec -it quassel-core /bin/bash
```- To monitor the logs of the container in realtime:
```bash
docker logs -f quassel-core
```- Container version number:
```bash
docker inspect -f '{{ index .Config.Labels "build_version" }}' quassel-core
```- Image version number:
```bash
docker inspect -f '{{ index .Config.Labels "build_version" }}' lscr.io/linuxserver/quassel-core: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:
```bash
docker-compose pull
```
* Single image:
```bash
docker-compose pull quassel-core
```- Update containers:
* All containers:
```bash
docker-compose up -d
```
* Single container:
```bash
docker-compose up -d quassel-core
```- You can also remove the old dangling images:
```bash
docker image prune
```Via Docker Run
- Update the image:
```bash
docker pull lscr.io/linuxserver/quassel-core:latest
```- Stop the running container:
```bash
docker stop quassel-core
```- Delete the container:
```bash
docker rm quassel-core
```- Recreate a new container with the same docker run parameters as instructed above (if mapped correctly to a host folder, your
/configfolder and settings will be preserved) - You can also remove the old dangling images:
```bash
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-quassel-core.git

Serve quassel-core on your own domain behind Caddy, Nginx or Traefik. Fill in your domain and copy the result. It's a starting point, some apps need their own base URL or extra headers set too.
Proxying quassel-core.example.com to http://quassel-core:4242
Add this to your Caddyfile
quassel-core.example.com {
reverse_proxy http://quassel-core:4242
}Check the logs first
Nine times out of ten the logs tell you exactly what went wrong.
- In Portainer, go to Containers, click the container, then Logs. Or run
docker logs <container> - Exit codes help too:
137means killed, usually out of memory.126or127means the command inside the image is broken.
Published on a random port
This template exposes 4242/tcp without setting a host port,
so Docker picks a random free one on every deploy.
- Find it in the Ports column of Portainer's container list, or with
docker port <container>
Image won't pull
Test the pull directly on the host: docker pull linuxserver/quassel-core:latest
- "manifest unknown" means the tag no longer exists. This template uses
latest, so try pinning a specific version instead. - "toomanyrequests" is the Docker Hub rate limit. Log in with
docker loginto raise it. - "no space left on device" means a full disk. Reclaim space with
docker system prune
"exec format error"
This means the image was built for a different CPU architecture than your server.
- This image supports:
amd64, arm64 - Check yours with
uname -m: x86_64 is amd64, aarch64 is arm64. Raspberry Pi and other ARM boards are the usual culprits.

A single container
quassel-core runs as one container, the simplest kind of app here. Just the one image to pull and nothing else wired up alongside it.
The app image
An image is the app packed up ready to go, everything quassel-core needs bundled into one download. This template pulls linuxserver/quassel-core:latest, which Docker fetches once (about 65 MB) and then starts your own copy from.
Where the image comes from
Docker pulls its images from registries, public libraries of ready-built apps. quassel-core's comes from Docker Hub, published by linuxserver.
Version tags
The bit after the colon in the image name is the version tag. Here it's latest, which always points at the newest build, so a redeploy can bump you to a newer release without you asking. Newest right now is 0.14.0. Pin a specific tag if you would rather stay on one version.
Which machines it runs on
Every image is built for particular CPU types. This one ships for amd64, arm64, so it runs on both regular x86 servers and ARM boards like a Raspberry Pi.
Ports
A port is the door the app answers on. Here the app exposes a port but leaves the host side blank, so Docker picks a free one for you. It opens:
4242, published on a random host port
Volumes
A volume is where quassel-core keeps its files so they survive an update or a restart. Without one, anything it saves would sit inside the container and vanish the moment it's recreated. This template mounts:
/configas a volume Docker manages for you
Environment variables
Environment variables are the settings you hand over when you deploy, things like a password or a timezone. quassel-core takes 3 of them, all with defaults you can leave alone or tweak:
PGID, defaults to1000PUID, defaults to1000TZ, defaults toAmerica/Chicago
Users and permissions
The PUID and PGID settings tell it which user and group to act as on your host. Point them at your own account (find yours with id $USER) so the files it writes into your mounted folders come out owned by you rather than root.
Networking
Nothing custom is set, so quassel-core sits on Docker's default bridge network: its own private space that reaches the outside world only through the ports it publishes.
Platform
The platform is linux, the kind of system the container is built to run on. Docker and Portainer handle this on a normal Linux server.
Portainer app templates
Zooming out, this whole page comes from a Portainer app template: a short recipe telling Portainer how to set quassel-core up. Add the template list to Portainer once, then deploying quassel-core is a click rather than a wall of config.
