About our Docker image
The Docker image is based on latest stable Fedora. It includes Spectrum 2 and also lot of 3rd-party backends you would have to compile or install yourself when not using Docker image. This includes:
- Facebook (purple-facebook plugin)
- Whatsapp (transwhat backend)
- IRC (libcommuni backend)
- Skype (purple-skypeweb plugin)
- libpurple backend
At first you have to install Docker. This is very well described on the official Docker Installation page.
Pull the Spectrum 2 Docker image
To download Spectrum 2 Docker image to your system, just run following command:
$ docker pull spectrum2/spectrum2
You can also update Spectrum 2 using this command later.
Create directory for Spectrum 2 configuration files
Now you have to decide where to store the configuration files for Spectrum 2. We will use
/opt/spectrum2/configuration in our example:
$ mkdir -p /opt/spectrum2/configuration
Create configuration file
You can use following default configuration files as a starting place:
Download the configuration file you chose into
/opt/spectrum2/configuration directory you have created earlier and edit it as you want. Check the documentation and tutorials for configuration examples.
Note that the configuration files must have
.cfg file extension.
Create directory for Spectrum 2 data
You also have to create persistent directory to store various Spectrum 2 data like SQLite3 database and so on:
$ mkdir -p /opt/spectrum2/data
Start Spectrum 2
To start Spectrum 2 on background using Docker, all you have to do is running following Docker command:
$ docker run --name="spectrum2" -d -p 5222:5222 -v /opt/spectrum2/configuration:/etc/spectrum2/transports -v /opt/spectrum2/data:/var/lib/spectrum2 spectrum2/spectrum2
It will start Spectrum 2 and load the configuration files from
/opt/spectrum. It also gives the spawned container name
Checking the Spectrum 2 logs
To check the Spectrum 2 logs, use following Docker command:
$ docker logs spectrum2
Stopping the Spectrum 2
To stop the Spectrum 2 container, use following Docker command:
$ docker stop spectrum2
Upgrading the Spectrum 2 container
To upgrade Spectrum 2 container, you at first have to pull the updated Docker image, stop the current container, remove it and start it again using the new version of Docker image. It is very important to have all the Spectrum 2 data stored in the host system as described earlier in this document. Otherwise you won’t be able to upgrade running container without loosing the data.
$ docker pull spectrum2/spectrum2 $ docker stop spectrum2 $ docker rm spectrum2 $ docker run --name="spectrum2" -d -p 5222:5222 -v /opt/spectrum2/configuration:/etc/spectrum2/transports -v /opt/spectrum2/data:/var/lib/spectrum2 spectrum2/spectrum2
