Issue in deploying a simple docker image to openshift

I was prototyping Openshift Origin latest version.

OS : RHEL 7.3

Docker : 17.05.0-ce

oc v1.5.1+7b451fc

kubernetes v1.5.2+43a9be4

  • Installation is done using a sudo user
  • Started the openshift using oc cluster up
  • Logged into openshift as the default user developer
  • Tried to deploy the docker helloworld app using oc new-app hello-world
  • Used oc get pod to get the status
  • Status is error

NAME READY STATUS RESTARTS AGE

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

  • Checked the logs using oc logs hello-world-1-deploy the error shown is

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

Tried google and got a lot of similar issue references, most said it is fixed in the latest versions (or similar answers). Looks like a kubernetes issue, but still no luck. Being a newbie is not getting the direction. Can anyone give some idea about this error.

Errors found on running oc adm diagnostics

   See the errors below in the output from the diagnostic pod:

[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.

Resolution (update)

  1. Uninstalled the 1.13 latest and installed the 1.12 latest docker-engine.
  2. Installation done using the centos repository. Reference
  3. Commands used

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

尝试根据此注释将docker降级至1.13.1。
