/home/ volume

[mboehm21]

Hi,

is there a reason why you define the /home/ directory as a volume in the Dockerfile? I get that this is for persistence but in my opinion this should be handled during deployment (in docker-compose.yml). Then the user could decide if he wants persistence or not. For my use case I want the home directorys to be repopulated when a new container is deployed.

Thanks.

Your compose file is leading, it is ment for automatic deployment.

When I don’t define a volume in docker-compose.yml, an unnamed volume is created for /home/ because it is defined in the Dockerfile. How can I avoid this?

Don't use docker-compose and run """docker run -d --name uxrdp --hostname terminalserver --shm-size 1g -p 3389:3389 -p 2222:22 danielguerra/ubuntu-xrdp:20.04"""

Does not really matter whether you provision it with docker or docker-compose:

mboehm21@dws-mboehm21:~$ docker run -d --name uxrdp --hostname terminalserver --shm-size 1g -p 3389:3389 -p 2222:22 danielguerra/ubuntu-xrdp:20.04

The volumes are created in both ways. The latter volume is the homedir which I want to avoid being created for my setup.

Sorry, but thats with any container that will write files , like logs ...
