Hi Niranjan,
default access permission is 0600 on /run/podman/io.podman directory, so you can't use non-root user
to access this listening directory, but you may modify permission before starting io.podman.socket,
good luck!
Ah thanks, Since the container was started by non-root user, when i tried with sudo it failed
$ sudo varlink call -m unix:/run/podman/io.podman/io.podman.ListContainerProcesses '{"name": "mysssd", "opts": []}'
Unable to connect: CannotConnect
Probably because the root user doesn't see the container .

Even after changing the permissions to 0666, as non root user i am still unable to use varlink to access the container. Any info on how i could use varlink as non root user to access containers created using non-root user.
