Hi all

I created my first docker (based on one found in hub) but if i wan to ssh it i creceive an errore (the same error appers in the original docker image):

rpc error: code = 2 desc = oci runtime error: exec failed: container_linux.go:247: starting container process caused “process_linux.go:87: adding pid 22700 to cgroups caused "failed to write 22700 to cgroup.procs: write /sys/fs/cgroup/systemd/docker/54cce0e5155bfc766e8a33f4faf6c52911ae78bbecdf215835389e25d1a70003/cgroup.procs: no space left on device"”

can someone please support me?

below the docker file content

FROM ubuntu:16.04
RUN  apt-get update
RUN  apt-get install -y \
     wget
	 RUN  wget -q -O - https://apt.mopidy.com/mopidy.gpg | apt-key add -

Thank you in advance!

seems like you have run out of space

This was my first thought but the volume in which docker is installed has a lot of space, and the other containers don’t show the same message.

How can I fix it?

Update:

I ran

docker system prune -a

but the issue is still there (also if I have 786 GB free).

i do not know myself… but it looks like a config issue…

And I think I’m not the only one facing this issue!

yep, looks like a bug… others have worked around by rebooting the docker host

I tried rebooting my Synology NAS. Nothing changed :frowning:
