Docker 客户端实际上无法连接到 Docker Hub 来拉取 ucp 映像[#37532]。所以我们有杠杆docker save
和docker load
命令。使用 解压缩 tar 文件后docker load
,ucp 映像就在那里。
但是当我们运行镜像时出现以下错误:
-bash-4.2$ docker container run --rm -it --name ucp -v /var/run/docker.sock:/var/run/docker.sock docker/ucp:3.0.2 install --host-address <node-ip-addr> --interactive --registry-username [$REGSITRY_PASSWORD] --registry-password [$REGISTRY_USERNAME]

After referring multiple forums and this article, we had added Google's DNS nameservers.
这是我们的 resolv.conf 文件:
-bash-4.2$ cat /etc/resolv.conf
nameserver 8.8.8.8
nameserver 8.8.4.4
#nameserver 127.0.0.1
search 1234.com
nameserver 127.0.0.1
nameserver xx.xx.xx.xx
nameserver xx.xx.xx.xx
nameserver xx.xx.xx.xx
问题是我们无法重新启动服务器,因为它位于我们公司的 DMZ 中(在代理之后),并且还有其他服务也在运行。所以,我们真的不能重启服务器。
我们要求社区为我们提供解决方案。
