I'm working on OpenShift Origin 1.1 (which is using kubernetes as its orchestration tool for docker containers). I'm creating pods, but I'm unable to see the build-logs.
[user@ip master]# oc get pods
NAME READY STATUS RESTARTS AGE
test-1-build 0/1 Completed 0 14m
test-1-iok8n 1/1 Running 0 12m
[user@ip master]# oc logs test-1-iok8n
Error from server: Get https://ip-10-0-x-x.compute.internal:10250/containerLogs/test/test-1-iok8n/test: dial tcp 10.0.x.x:10250: i/o timeout
My /var/logs/messages shows:

My versions are:
origin v1.1.0.1-1-g2c6ff4b
kubernetes v1.1.0-origin-1107-g4c8e6f4
etcd 2.1.2
I forgot to open port 10250 (tcp) (in my aws security group). This was the only issue for me.
