Hi @jorvis ---

We have an[official Docker image](https://hub.docker.com/r/qiime2/core/), I would suggest starting there! We have done all the necessary configuration to get it up and running in a container format for you!

To comment on your specific error, because Docker is running in a headless environment (e.g. Docker), you have to [configure your Matplotlib Backend as such](https://forum.qiime2.org/t/matplotlib-configuration-issues/185/2). Moving forward though I would recommend our official QIIME 2 Docker image! Thanks!
