### Note

If you are using Docker bridge networking, you should configure your XMPP server to listen on the bridge IP address. Some XMPP servers listen only on 127.0.0.1 by default. Check [Prosody](https://prosody.im/doc/components) documentation for example config.  

## 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/spectrum

	$ docker stop spectrum2

	$ docker rm spectrum2
