howto rootless podman container connecting to REST api /var/run/docker.sock

Ok I was struggling a bit finding info about this. In a nutshell:

  • /var/run/docker.sock only works for root(ful) containers
  • there's no rootless socket-file created by default (you need to run an API listener service)

STEP 1: run API listener service (to create socketfile)
