Podman images not showing with podman image ls

I am trying to setup a build server in a Red Hat Enterprise Linux 8 (CentoOS 8) virtual machine.

I installed podman by running sudo dnf install -y @container-tools

I then ran sudo podman pull mcr.microsoft.com/dotnet/core/aspnet:3.1-buster-slim to pull a container image from docker:

This looks successful to me. And if I run it again, I get told that the layers "already exists". But then I run:

podman image ls

and I get an empty list back:

REPOSITORY TAG IMAGE ID CREATED SIZE

I also tried the following commands to get a list:

  • podman image ls -a
  • podman image list
  • podman image list -a
  • podman images
  • podman images ls
  • podman images ls -a
  • podman images list
  • podman images list -a

They all give an empty list.

How can I see the container image that I pulled down?

Update: I ran sudo podman run --rm --name=linuxconfig-test -p 80:80 httpd and (on another machine) browsed to the ip address of my linux machine and got It Works! shown. So podman is working at least in part.

Solution

  • Turns out you have to run using sudo. I ran :

    sudo podman image ls

    and it returned the list of container images.
