Common problems

Did not resolve to an alias

If referencing an image, say postgres:14, the following error shows:

Error: short-name "postgres:14" did not resolve to an alias and no unqualified-search registries are defined in "/etc/containers/registries.conf"

It can be the case that you referencing unqualified images¹. The previous behaviour (using unqualified image names) can be restated by adding the line below in /etc/containers/registries.conf.

unqualified-search-registries = ["docker.io"]
