Grafana on rootless podman?

I am trying to install Grafana on rootless podman, but the pull command gets the following error:

guru@stormwind  ~  podman pull grafana/grafana
Completed short name "grafana/grafana" with unqualified-search registries (origin: /home/guru/.config/containers/registries.conf)

I’m looking at this now too. Starting to build a test setup on Centos7.9

What UID number are you running the podman pull as?

I think what you are seeing might be to do with sub{uid,gid}

See (section: Rootless Podman):

Getting closer. Working on a systemd file…

Created host OS grafana user with 472:472 member of grafana group (again 472)

Bind mounting folders from host OS. Those folders are grafana:root owned on host OS and perms 775.
