Podman : Use Registry2019/11/19 |
|
Install Registry to build Private Registry for Container Images.
|
|
| [1] |
On The Host the Registry Container runs, Get SSL Certificates, refer to here.
This example is based on the case that SSL certificates are gotten under the [/etc/letsencrypt/live/dlp.srv.world] and set the [Common Name] as [dlp.srv.world]. |
| [2] | Copy Certificates and pull Registry Image (v2). Container Images are located under [/var/lib/regstry] on Registry v2 Container, so map to mount [/var/lib/docker/registry] on parent Host for Registry Container to use as Persistent Storage. |
