I have setup this https://github.com/actions-runner-controller/actions-runner-controller in my eks cluster. That creates per each runner a docker contanier and a runner container. In order to share docker images and not pull every time I have created a volume to share the /var/lib/docker and injects it in all docker containers. The problem is that time to time (with 1 or 2 pods does not fails) the docker container fails initialization with this error:

evel=warning msg="grpc: addrConn.createTransport failed to connect to {unix:///var/run/docker/containerd/containerd.sock <nil> 0 <nil>}. Err :connection error: desc = \"transport: error while dialing: dial unix:///var/run/docker/containerd/containerd.sock: timeout\". Reconnecting..." module=grpc

I have created in the repo an issue in the repo but I dont think the error is related with the controller. Is something on my side.
