docker - 未找到 openshift v3 pod 文件

Question

我正在测试 Openshift Origin v3。我按照说明将它安装为 docker 容器。我还在角色/openshift_examples/files/examples/image-streams/image-streams-centos7.json 中部署了所有流。

我现在正在通过从 Github 部署一个虚拟 php 应用程序来测试安装。我能够创建项目和应用程序。但是，构建卡在“待定”状态。在事件选项卡中，我看到很多这样的消息:

"Unable to mount volumes for pod "hello-world-1-build_php1": 
IsLikelyNotMountPoint("/var/lib/origin/openshift.local.volumes/pods/9377d3b4-9887-
11e5-81fe-00215abe5482/volumes/kubernetes.io~secret/builder-dockercfg-x2ijq-
push"): file does not exist (5 times in the last 40 seconds)"

我也尝试了 java 应用程序和 tomcat docker 镜像，但得到了相同的错误消息。看起来像是 Kubernetes 配置问题。

有什么想法吗？

感谢您的帮助

更新1:来自源容器的日志显示了有关错误的更多信息:

@Clayton:你能分享任何关于应该在 1.10 中修复的挂载错误的链接吗？谢谢!

Answer 1

您使用的是什么操作系统和 Docker 版本？在旧版本的 Docker 上挂载卷存在已知问题 - OpenShift/Kube 将卷挂载到容器中，但是当 Docker 运行 OpenShift 时，现有的 Docker 版本隐藏了对根挂载的访问。 Red Hat OS 有一个补丁可以让这个工作正常进行，据说 Docker 1.10 会进行正确的修复。另一种方法是直接下载二进制文件并简单地使用 sudo openshift start 启动它。
