I've installed the Docker (19.03.11) on Ubuntu (20.04) based on this article: https://docs.docker.com/engine/install/ubuntu/
What would be the goal
I would like to change the data-root and tls options so I search for the config possibilities.
What options I used
- /etc/docker/daemon.json (not exits by default!)
The procedure I followed
I tried all these files with the following procedures:
service docker stop
[edit the file]
service docker start
What worked somehow
I can only apply the data-root option by edit the docker.service file (however) it was reset when I instelled the docker-compose, so I guess the solution is not there.
- What did I miss that cause the above solutions are not working?
- Any more option where could I pass arguments to the dockerd executable? (beside I manually start it or create my own script in the init.d folder)
