A short name is a container image reference such as ubi8 that omits the registry and other fully qualified components. Podman resolves it through configured registries rather than assuming one fixed registry. section 1.3.9 section 2.2.8
Podman uses short names in two practical ways:
- It searches configured registries and can prompt for a choice when several registries provide a possible match. section 1.3.9 section 2.2.8
- It can persist a selected short-name alias or use aliases configured in registries.conf.d, while fully qualified names remain available for explicit selection. section 1.3.9 section 2.2.8
Pulling with a short name
Running podman create -p 8080:8080 ubi8/httpd-24 can present registry.fedoraproject.org, registry.access.redhat.com, docker.io, and quay.io as choices. A fully qualified alternative is registry.access.redhat.com/ubi8/httpd-24:latest. section 2.2.8 section 1.3.9
