Resolving - Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock

When running any docker command, via some other user, not root,  and getting error as - Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock  is fixable by fixing the permission for /var/run/docker.sock file.

Docker tool is install with 'root' user hence all the files and folder is owned by 'root' user only,  Let's check what permission is there for /var/run/docker.sock 

$ ls -l /var/run/docker.sock
srw-rw---- 1 root root 0 Jan 21 13:42 /var/run/docker.sock

As we can see, file's user and group is 'root' hence we are getting permission denied error. To fix this problem, change the permission of /var/run/docker.sock as below -

$ chmod 666 /var/run/docker.sock
srw-rw-rw- 1 root root 0 Jan 21 13:42 /var/run/docker.sock

We have given read/write permission to all other users by running above command, now, if we run any docker command, we will not see the permission denied error.
