cannot access containerd socket "/run/containerd/containerd.sock": no such file or directory

[aishwaryabk]

I am trying to create a container inside a container using nerdctl command:

root@69adc10b8807:/home/jenkins/workspace/# nerdctl version
Client:
 Version:       v0.8.0
 Git commit:    d57846db4a90540bc41e4683cd1a9f1e9e99170a
FATA[0000] cannot access containerd socket "/run/containerd/containerd.sock": no such file or directory

root@69adc10b8807:/home/jenkins/workspace/# nerdctl run -it ubuntu
FATA[0000] cannot access containerd socket "/run/containerd/containerd.sock": no such file or directory

root@69adc10b8807:/home/jenkins/workspace/# ls /run/
lock  utmp

root@69adc10b8807:/home/jenkins/workspace/# find / -name containerd.sock
root@69adc10b8807:/home/jenkins/workspace/#

The /run/containerd/containerd.sock is not present.

sudo systemctl enable --now containerd

This command is run inside the container of quay.io/powercloud/inbound-agent:4.10-3.2 image and so sudo: systemctl: command not found

You need more configuration. I believe that this discussion will help you

Hi @fahedouch, I tried following the doc (https://github.com/containerd/nerdctl/blob/main/docs/rootless.md).
I created a new user and tried installing containerd using the rootless approach.

root@69adc10b8807:/home/jenkins/workspace/# su aish
$  sudo /usr/local/bin/containerd-rootless-setuptool.sh install
[sudo] password for aish:
[ERROR] Refusing to install rootless containerd as the root user
$ /usr/local/bin/containerd-rootless-setuptool.sh install
[ERROR] Needs systemd (systemctl --user)
$
$ systemctl
sh: 4: systemctl: not found

But this does not work. Is there any other approach for solving this? Or am I missing anything?

hi @aishwaryabk , Sorry but do not understand the relation between setting up a rootless environment and the original issue to access containerd socket from the container
