No pods created after launching a DaemonSet

Question

I'm trying to create a DaemonSet on a cluster of 6 nodes. It shows that the DaemonSet has been deployed successfully but there are no pod being scheduled on the nodes:

> ic describe ds
Name:       dd-agent
apiVersion: extensions/v1beta1
Image(s):   datadog/docker-dd-agent:kubernetes
Selector:   app=dd-agent,name=dd-agent,version=v1
Node-Selector:  <none>
Labels:     release=stable,tech=datadog,tier=backend
Desired Number of Nodes Scheduled: 0
Current Number of Nodes Scheduled: 0
Number of Nodes Misscheduled: 0
Pods Status:    0 Running / 0 Waiting / 0 Succeeded / 0 Failed
No events.
Setup

I'm using AWS for this and created the cluster using kube-aws. I'm already running about 30 pods across these 6 nodes.

• CoreOS alpha (891.0.0)
• Kubernetes server v1.1.2
• Updated the /etc/kubernetes/manifest/kube-apiserver.manifest to enable DaemonSets by adding --runtime-config=extensions/v1beta1/daemonsets=true

I've tried restarting kubelet and even the used daemon-reload command but to no effect. Please help.

Kubelet service restart won't help you with restarting the pods being managed. DaemonSets are managed by contoller manager. So you need to check if the feature is enabled in apiserver, so make sure that the apiserver is running with the alpha extensions and then restart the controller manager.
