Azure容器服务无法安装docker-engine

Question

我已经部署了一个新的资源组和kubernetes集群，使用acs-engine在VSTS中通过这些ARM模板提取文章并发布。但是，当您通过ssh进入主docker-engine时，kubernetes集群就被创建了。正在运行

`systemctl status kubelet` 

显示服务已死，当您尝试运行它时，它会显示docker.service已死。无法启动，因为docker引擎不在那里。

当您尝试运行一个apt-get install docker-engine时，它会失败，正如您在上面看到的。

通过运行sudo apt-get install -y --allow-unauthenticated docker-engine，您可以安装docker引擎并启动kubelet服务。然后，您可以从主服务器访问集群。

但是，由于没有创建.kube/config，因此您无法从外部源访问它。我可以从主机创建.kube/config，现在正在研究这一点。

这个问题需要解决，因为我正在自动化环境部署。

PR https://github.com/Azure/acs-engine/pull/498修复了获取GPG失败的问题。您能确认您使用的是最新的acs-engine吗?如果是，请发送您看到此消息的区域。

为了确认正确运行，我刚刚在我们西部部署了ACS-Engine中的最新版本，还验证了我们的跑步者没有在Azure区域显示此问题。
