You need to have podman varlink running locally in your homedir for this to work.  I know their is effort to make this happen seamlessly. I know that the Cockpit team have been working on making this happen, but I need Jhon or Brent or Martin to chime in on how it works (Or doesn't) On 8/12/19 2:37 AM, niranjan(a)ashoo.in wrote:

Hello all, Daniel Walsh [2019-08-12 8:55 -0400]: Indeed podman's service file almost works for the systemd user instance. Matej recently sent https://github.com/containers/libpod/pull/3662 to make varlink on the user instance work out of the box.
