问题部署一个简单的泊坞窗图像openshift
我原型是Openshift Origin的最新版本。
操作系统：RHEL 7.3
Docker：17.05.0-ce
oc v1.5.1 + 7b451fc
kubernetes v1.5.2 + 43a9be4
- 安装使用sudo用户完成
- 使用
oc cluster up启动openshift - 作为默认的用户开发人员login到openshift
- 尝试使用
oc new-app hello-world部署docker helloworld应用oc new-app hello-world - 使用
oc get pod以获取状态 - 状态是错误的
名称就绪状态RESTARTS AGE
hello-world-1-deploy 0/1错误0 57m
- 使用
oc logs hello-world-1-deploy检查oc logs hello-world-1-deploy所显示的错误是
错误：打开/var/run/secrets/kubernetes.io/serviceaccount/token：没有这样的文件或目录
试过谷歌，并得到了很多类似的问题的参考，大多数表示它是固定在最新版本（或类似的答案）。 看起来像一个kubernetes问题，但仍然没有运气。 作为一个新手没有得到方向。 任何人都可以对这个错误有所了解。
运行oc adm diagnostics发现错误

决议（更新）
- 卸载1.13最新的并安装了1.12最新的docker引擎。
- 使用centos存储库完成安装。 参考
- 使用的命令
安装依赖se-linux
sudo yum安装docker-engine-selinux-1.12.6-1.el7.centos.noarch
安装docker引擎
sudo yum安装docker-engine-1.12.6-1.el7.centos.x86_64
尝试将Docker降级到1.13.1。
