Issue in deploying a simple docker image to openshift

I was prototyping Openshift Origin latest version.

OS : RHEL 7.3

  • Create django super user in a docker container without inputting password
  • Docker proxy with custom networks
  • Open existing nvidia-docker container
  • Setting environment variables when running docker in detached mode
  • Docker login working only with daemon but not with Docker active service
  • Making a karaf/docker service read a configuration file
  • 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

       The "docker-registry" service exists but has no associated pods, so it
       is not available. Builds and deployments that use the registry will fail.

       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

    Try downgrading docker to 1.13.1 per this comment.

    Docker will be the best open platform for developers and sysadmins to build, ship, and run distributed applications.
