Hi @mhs-achyut , thanks for using this action. From the log, I can conclude that, this is an issue with the Github Action Runner machine. The runner machine docker command can not find the unix:///var/run/docker.sock and thats why it is failing. Could you try re-running the job?

[mhs-achyut]

no luck, it is the same problem. I restarted the host machine, restarted the docker service, and also restarted the jobs. But with no luck. I can see the docker service active:

sudo systemctl status docker [sudo] password for administrator:  ● docker.service - Docker Application Container Engine      Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)      Active: active (running) since Mon 2021-06-07 17:01:39 EDT; 29min ago TriggeredBy: ● docker.socket        Docs: https://docs.docker.com    Main PID: 1800 (dockerd)       Tasks: 21      Memory: 199.5M      CGroup: /system.slice/docker.service              └─1800 /usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock

I was using iterative/cml repo for my runners. Anyways, if I use a native machine instead of docker, this action works. FYI, for anyone who might stumble here in the future.
