Hi all,
I've the issue that docker container do not start.
I tried following command:
| Code: | | docker run kubler/mariadb |
The error message is:
| Code: | docker: Error response from daemon: OCI runtime create failed: container_linux.go:349: starting container process caused "process_linux.go:449: container init caused \"process_linux.go:415: setting cgroup config for procHooks process caused \\\"error while setting cgroup v2: [failed to load program: function not implemented]\\\"\"": unknown.
ERRO[0000] error waiting for container: context canceled |
docker daemon is active (systemd)
Kernel: 5.4.97
When I execute the docker check script I get this output

There are settings as "MISSING" declared that leads to some problems:
- CONFIG_NETFILTER_XT_MATCH_IPVS This option is not present in the kernel config
- CONFIG_RT_GROUP_SCHED: When I enable this option the system does not start anymore. Is hangs after the last message ("[OK] terminate plymouth..."). No login prompt and no sddm
The Docker Wiki page does not match my kernel version. The Wiki page says that CFQ IO Scheduler should be enabled, but I do not have this option in my kernel config (there is BFQ instead)
I tried with the kernel boot option "systemd.unified_cgroup_hierarchy=0" and "systemd.unified_cgroup_hierarchy=1" as well. But nothing helped. |
