I believe that this PR here will improve that situation: https://github.com/kubernetes/kubernetes/pull/48589 Backported to Origin in this pick set: https://github.com/openshift/origin/pull/16865 Basically the generic "Error syncing pod", which tells the user nothing, will be replaced with a event with Reason "FailedCreatePodSandBox" and Message "Failed create pod sandbox.". The error from the runtime is still eaten though. Derek, you were just in this part of the code. What do you think? Origin PR: https://github.com/openshift/origin/pull/18002 OSE 3.7 PR: https://github.com/openshift/ose/pull/985 Checked with # openshift version openshift v3.7.26 kubernetes v1.7.6+a08f5eeb62 etcd 3.2.8 And currently will display a FailedCreatePodSandBox event when describe the pod. So verify this issue. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.

If the ose-pod image cannot be pulled pods will (obviously) not launch. But this is not easy to detect. oc describe on a pod that is unable to start because of this looks like: ``` Events: FirstSeen LastSeen Count From SubObjectPath Type Reason Message --------- -------- ----- ---- ------------- -------- ------ ------- 26m 26m 1 default-scheduler Normal Scheduled Successfully assigned frontend-3v3gk to ip-172-31-55-154.ec2.internal 26m 1m 112 kubelet, ip-172-31-55-154.ec2.internal Warning FailedSync Error syncing pod ``` In the node logs you might see a message like: ``` remote_runtime.go:86] RunPodSandbox from runtime service failed: rpc error: code = 2 desc = unable to pull sandbox image "registry.reg-aws.openshift.com:443/openshift3/ose-pod:v3.6.173.0.49": manifest unknown: manifest unknown ``` We found this because we had the node-config.yaml pointing to a registry which didn't contain the ose-pod image: ``` imageConfig: format: registry.something.com:443/openshift3/ose-${component}:${version} latest: false ```
