Testing result of new atomic-6 image [1] built by Tango
atomic-5 image has issue to start a container instance(docker version is 
1.7.1), Tango built a new atomic-6 image with docker 1.8.1 version.
eghobo and I (eliqiao) did some testing works (eghobo_ did most of them)

Here is the summary:

  * coe=swarm

 1.      can not pull swarm:0.2.0, try to use 0.4.0 or latest works
 2.      when creating a container with magnum CLI, the image name
    should use full name like "docker.io/cirros"

examples for 2:

    /taget at taget-ThinkStation-P300:~/kubernetes/examples/redis$ magnum
    container-create --name testcontainer --image cirros --bay swarmbay6
    --command "echo hello"//
    //ERROR: Docker internal Error: 404 Client Error: Not Found ("No
    such image: cirros") (HTTP 500)//
    //taget at taget-ThinkStation-P300:~/kubernetes/examples/redis$ magnum
    container-create --name testcontainer --image docker.io/cirros --bay
    swarmbay6 --command "echo hello"


  * coe=k8s (tls_disabled=True)

kube-apiserver.service can not start up , but could use command line[2] 
to start, I tried to use kubctl get pod, but failed as

    /[minion at k8-5qx66ie62f-0-vaucgvagirv4-kube-master-oemtlcotgak6 ~]$
    kubectl get pod/
    /error: couldn't read version from server: Get
    http://localhost:8080/api: dial tcp connection refused/

netstat shows that 8080 is not in listened, not sure why(not familiar 
with k8s)

    /[minion at k8-5qx66ie62f-0-vaucgvagirv4-kube-master-oemtlcotgak6 ~]$
    ps aux | grep kub/
