docker - 将简单的 docker 镜像部署到 openshift 的问题

Question

我正在制作 Openshift Origin 最新版本的原型(prototype)。

操作系统:RHEL 7.3

docker :17.05.0-ce

oc v1.5.1+7b451fc

Kubernetes v1.5.2+43a9be4

使用 sudo 用户

完成安装

使用 oc cluster up 启动 openshift

以默认用户 developer

登录 openshift

尝试使用 oc new-app hello-world 部署 docker helloworld 应用程序

二手 oc get pod获取状态

状态为错误

NAME READY STATUS RESTARTS AGE

hello-world-1-deploy 0/1 Error 0 57m

使用 oc logs hello-world-1-deploy 检查了日志显示的错误是

error: open /var/run/secrets/kubernetes.io/serviceaccount/token: no such file or directory

尝试谷歌并获得了很多类似的问题引用，大多数人说它已在最新版本(或类似答案)中修复。看起来像一个 kubernetes 问题，但仍然没有运气。作为一个新手是没有方向的。任何人都可以对这个错误给出一些想法。

运行时发现错误 oc adm diagnostics

[Note] Running diagnostic: DiagnosticPod
   Description: Create a pod to run diagnostics from the application standpoint

ERROR: [DCli2012 from diagnostic DiagnosticPod@openshift/origin/pkg/diagnostics/client/run_diagnostics_pod.go:155]
   See the errors below in the output from the diagnostic pod:
   [Note] Running diagnostic: PodCheckAuth
          Description: Check that service account credentials authenticate as expected

   ERROR: [DP1001 from diagnostic PodCheckAuth@openshift/origin/pkg/diagnostics/pod/auth.go:53]
          could not read the service account token: open /var/run/secrets/kubernetes.io/serviceaccount/token: no such file or directory

   [Note] Running diagnostic: PodCheckDns
          Description: Check that DNS within a pod works as expected

   [Note] Summary of diagnostics execution (version v1.5.1+7b451fc):
   [Note] Errors seen: 1

[Note] Running diagnostic: NetworkCheck
   Description: Create a pod on all schedulable nodes and run network diagnostics from the application standpoint

ERROR: [DNet2001 from diagnostic NetworkCheck@openshift/origin/pkg/diagnostics/network/run_pod.go:77]
   Checking network plugin failed. Error: User "developer" cannot get clusternetworks at the cluster scope


[Note] Running diagnostic: ClusterRegistry
   Description: Check that there is a working Docker registry

ERROR: [DClu1006 from diagnostic ClusterRegistry@openshift/origin/pkg/diagnostics/cluster/registry.go:209]
   The "docker-registry" service exists but has no associated pods, so it
   is not available. Builds and deployments that use the registry will fail.

[Note] Running diagnostic: ClusterRouterName
   Description: Check there is a working router

ERROR: [DClu2007 from diagnostic ClusterRouter@openshift/origin/pkg/diagnostics/cluster/router.go:156]
   The "router" DeploymentConfig exists but has no running pods, so it
   is not available. Apps will not be externally accessible via the router.

分辨率(更新)

卸载了最新的 1.13 并安装了最新的 1.12 docker-engine。

使用 centos 存储库完成安装。 Reference

使用的命令

Installing dependency se-linux

sudo yum install docker-engine-selinux-1.12.6-1.el7.centos.noarch

Installing docker-engine

sudo yum install docker-engine-1.12.6-1.el7.centos.x86_64

尝试根据 this comment 将 docker 降级到 1.13.1 .
