Image short names (i.e., those without a domain etc.) are treated differently in Podman. The following article goes into some of the details: https://www.redhat.com/sysadmin/container-image-short-names

In your specific case: Podman prefixes images with "localhost/" if the tag is a short name. So podman tag $image foo will actually tag the image as localhost/foo. If you run podman tag $image bar.com/foo it will be tagged exactly as such.

Is the behavior causing issues on your end?

i found the same issue containers/podman #1034

Just got bit by this too. How does this pain me? Kind doesn't assume that localhost/myimage:v0.1 and myimage:v0.1 are the same. So now I need to modify all my k8s yaml files to add the localhost/ prefix because I can't get Podman to remove it.
