Hello everyone, I just launched my own implementation of using Piwik with Docker. Besides that it uses Ansible to make the deploy as easy and fast as possible, only needing to run a command to get it all working.
Here is the repository: GitHub - pedrocaseiro/piwik-docker: Docker wrapper for the open-source analytics platform, piwik
Hope someone finds it usefull. It is working really well for me but if you find any problems with it, just tell me or open a pull request/issue.
