我已经使用 docker 分发注册表（不是旧的 docker-registry）安装了一个私有 docker 存储库。我可以从另一台机器上查询 api 并查看我推送的图像，但我无法拉取它。
在机器 AI 上安装了一个 docker 分发容器：
sudo docker run --name=registry --restart=always -d -p 5000:5000 registry:2.0
我已经在机器 A 上创建并推送了我的图像。
$ sudo docker push 192.168.0.14:5000/sample-web-app
The push refers to a repository [192.168.0.14:5000/sample-web-app] (len: 1)

然后我删除了机器 A 上的本地映像。
