!!! INFO !!!
This is a Docker [+ Compose] which is isolated from the host. Workspace will run its own rootless docker daemon. 

Compared to the Docker-host version of Alnoda Docker app, stadalone isolated docker daemon will require additional resources.

If you want to connect to the host Docker daemon from the workspace instead, install "host" version of Alnoda Docker app
