Error from server: dial tcp i/o timeout error when getting logs of pod

Question

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:

Dec  4 13:28:24 ip-10-0-x-x origin-master: E1204 13:28:24.579794   32518 apiserver.go:440] apiserver was unable to write a JSON response: 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 versions are:

origin v1.1.0.1-1-g2c6ff4b
kubernetes v1.1.0-origin-1107-g4c8e6f4
etcd 2.1.2

Answer 1

I forgot to open port 10250 (tcp) (in my aws security group). This was the only issue for me.
