Docker客户端实际上无法连接到Docker Hub来提取ucp映像[#37532]。因此,我们使用了docker save
和docker load
命令。在使用docker load
取消标记tar文件之后,ucp图像就在那里了。
但是,当我们运行图像时,会出现以下错误:
-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 8.8.4.4
#nameserver 127.0.0.1

nameserver xx.xx.xx.xx
nameserver xx.xx.xx.xx
问题是我们无法重新启动服务器,因为它位于我们的公司DMZ(在代理后面(,而且还有其他服务在运行。所以,我们真的无法重新启动服务器。
我们请求社区为我们提供解决方案。

查看错误消息的这一部分。We can not accurately detect available storage space. Please make sure you have at least 3.00 GB available in /var/lib/docker
尽量在/var/lib/docker中有更多的空间,在这个路径中安装其他目录/设备,使用符号链接或其他让docker下载映像的东西。

我在回答我自己的问题。
这个问题的解决方案在于保存和加载docker图像(包括所有子依赖图像(。我们不得不采用这种方法,因为我们的服务器在代理之后。Docker REST API无法建立与Docker Hub(外部世界(的连接。这就是上述错误浮出水面的原因。
离线的方法解决了我们的问题。我知道它很笨重,但它正在工作。
