Has anyone installed Piwik/Matomo on a Docksal environment?

Docksal is the containerized dev package created by FFW Agency (originally for Drupal development but it works with just about any technology since it is built on Docker containers).

I would like to deploy Matomo to my Drupal 7 site running on Docksal but I’m running into permission issues (Matomo “running as Docker” cannot write to various directories). I suspect the issue is with how the Docker container is provisioning the Matomo service but using chmod and chown on the directories doesn’t appear to help.
