问一下升级容器魔方，安装不了，怎么通过镜像安装？
按照 升级方法，手工升级后无法安装，报错如下：docker pull registry.hub.docker.com/onething1/wxedge
Using default tag: latest
Error response from daemon: Get "https://registry.hub.docker.com/v2/": net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)
Error: No such container: wxedge
