上傳 Image 到 Registry

1. 連線 registry，查看 images，回應不允許無認證存取。

   [root@registry ~]# curl https://registry.csie.cyut.edu.tw/v2/_catalog
   {"errors":[{"code":"UNAUTHORIZED","message":"authentication required","detail":
   [{"Type":"registry","Class":"","Name":"catalog","Action":"*"}]}]}
   podman login -uadmin -pxxxxxx https://registry.csie.cyut.edu.tw
   

2. 使用帳號 admin 查詢 registry.csie.cyut.edu.tw，repositories 中沒有任何的 image。

   [root@registry ~]# curl -u admin:xxxxxx https://registry.csie.cyut.edu.tw/v2/_catalog
   {"repositories":[]}
   

3. 下載 docker.io/library/hello-world。

   [root@registry ~]# podman pull docker.io/library/hello-world
   Trying to pull docker.io/library/hello-world...
