High-level goal: I want to build the carla-simulator in a docker environment.
Low-level goal:
My root file system does not have enough disk space. Therefore, I changed my docker data directory from /var/lib/docker/
to my internal HDD mounted at: /media/<username>/HDD
into the folder /media/<username>/HDD/docker/
which I created prior to changing my daemon.json
in /etc/docker/
. I followed this guide to achieve this modification https://www.guguweb.com/2019/02/07/how-to-move-docker-data-directory-to-another-location-on-ubuntu/.
This worked well until I rebooted.
My Problem:
Everytime I reboot, the name of my mounted HDD is incremented. After the first reboot, the name changed from HDD
to HDD1
, after the second reboot from HDD1
to HDD2
. This caused many problems and I am unable to relocate my docker data directory.
Removing the data-root
specification from the daemon.json
removed this problem, but I would like to relocate my docker data directory.
Suspected reasons: Maybe the docker deamon starts looking for the internal HDD before ubuntu mounts the drive. But I don't know what I could do to fix my problem.
Software in use:
- Ubuntu 20.04
- Docker 20.10.15
- HDD Partion as Ext4
