Moin,
the hard disk is almost full. As far as I see, there are 170 GB ununsed docker images:
renner@boulder:~$ docker system df
TYPE TOTAL ACTIVE SIZE RECLAIMABLE
Images 6 6 2.594GB 178.2MB (6%)
Containers 6 6 170.1GB 0B (0%)
Local Volumes 5 5 729.9kB 0B (0%)
Build Cache 0 0 0B 0B
following the instructions i tried various commands:
$ docker image prune -a -f
$docker system prune
$ docker system prune --volumes
$ docker container prune
But there are still unreclaimable.
$ docker container ls -a
only shows the running containers, only a few.
renner@boulder:~$ docker --version
Docker version 20.10.6, build 370c289
What did I miss?
