20.5. 将容器推送到私有注册中心

流程

1. 在机器上创建本地注册中心：

   # podman run -d -p 5000:5000 registry:2

2. 将 myecho:latest 镜像推送到 localhost 注册中心:

   #  buildah push --tls-verify=false myecho:latest localhost:5000/myecho:latest
   Getting image source signatures
   Copying blob sha256:e4efd0...
   ...
   Writing manifest to image destination
   Storing signatures

验证

1. 列出 localhost 存储库中的所有镜像：

   # curl http://localhost:5000/v2/_catalog
   {"repositories":["myecho2]}
   
   
   # curl http://localhost:5000/v2/myecho2/tags/list
   {"name":"myecho","tags":["latest"]}

2. 检查 docker://localhost:5000/myecho:latest 镜像：

   # skopeo inspect --tls-verify=false docker://localhost:5000/myecho:latest | less
   {
       "Name": "localhost:5000/myecho",
       "Digest": "sha256:8999ff6050...",
       "RepoTags": [
           "latest"
       ],
       "Created": "2021-06-28T14:44:05.919583964Z",
       "DockerVersion": "",
       "Labels": {
           "architecture": "x86_64",
           "authoritative-source-url": "registry.redhat.io",
       ...
   }

3. 拉取 localhost:5000/myecho 镜像：

   # podman pull --tls-verify=false localhost:5000/myecho2
   # podman run localhost:5000/myecho2
   This container works!
