Podman : Use Registry2022/04/28 |
|
Install Registry to build Private Registry for Podman images.
Pull the Registry image and run it. Container images are located under [/var/lib/regstry] on Registry v2 Container,
so map to mount [/var/lib/containers/registry] on parent Host for Registry Container to use as Persistent Storage. |
|
| [1] | Configure Registry. This is for the case to use HTTP and no authentication. |
