linuxserver/quassel-core

Docker Pulls Docker Stars Build Status

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

Our images support multiple architectures such as x86-64, arm64 and armhf. We utilise the docker manifest for multi-platform awareness. More information is available from docker here and our announcement here.

Simply pulling linuxserver/quassel-core 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 Tag
x86-64 amd64-latest
arm64 arm64v8-latest
armhf arm32v7-latest

Usage

Here are some example snippets to help you get started creating a container from this image.

docker

docker create \
  --name=quassel-core \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Europe/London \
  -e RUN_OPTS=--config-from-environment `#optional` \
  -p 4242:4242 \
  -p 113:10113 `#optional` \
  -v <path to data>:/config \
  --restart unless-stopped \
  linuxserver/quassel-core

docker-compose

Compatible with docker-compose v2 schemas.

---
version: "2"
services:
  quassel-core:
    image: linuxserver/quassel-core
    container_name: quassel-core
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/London
      - RUN_OPTS=--config-from-environment #optional
    volumes:
      - <path to data>:/config
    ports:
      - 4242:4242
    ports:
      - 113:10113 #optional
    restart: unless-stopped

Parameters

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)

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=Europe/London Specify a timezone to use EG Europe/London.
RUN_OPTS=--config-from-environment Custom CLI options for Quassel

Volume Mappings (-v)

Volume Function
/config Database and quassel-core configuration storage.

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)

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 behvior.

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
