Our docker-compose.yml does NOT yet install Rocket.Chat or Collabora, only the packages do!
The Rocket.Chat EGroupware app, is NOT the Rocket.Chat container/server, it’s just an EGroupware app to display Rocket.Chat inside EGroupware, it needs the container.
You can use the docker-compose file from Rocket.Chat itself:
You need to change the ROOT_URL to something matching your installation eg. https://domain.com/rocketchat and you need to set up a reverse proxy for /rocketchat into the container, like we do in your packages:
This are only pointers, I don’t have time to support you setting up your individual system, please use our packages, if you want Rocket.Chat and Collabora integration!
