I am new to kubernetes and trying to deploy openstack on kubernetes cluster, below is the error I see when I try to deploy openstack. I am following the openstack docs to deploy.
kube-system ingress-error-pages-56b4446784-crl85 0/1 Pending 0 1d
kube-system ingress-error-pages-56b4446784-m7jrw 0/1 Pending 0 5dI have kubernetes cluster with one master and one node running on debain9. I encounted this error during openstack installation on kubernetes.
Kubectl describe pod shows the event as below:
Events:
Type Reason Age From Message
---- ------ ---- ---- -------
Warning FailedScheduling 2m (x7684 over 1d) default-scheduler 0/2 nodes are available: 1 PodToleratesNodeTaints, 2 MatchNodeSelector.All I see is a failed scheduling, Even the container logs for kube scheduler shows it failed to schedule a pod, but doesn't say why it failed? I am kind of struck at this step from past few hours trying to debug....
PS: I am running debian9, kube version: v1.9.2+coreos.0, Docker - 17.03.1-ce
Any help appreciated ....
Looks like you have a toleration on your Pod and don't have nodes with the taints for those tolerations. Would help to post the definition for your Ingress and its corresponding Deployment or DaemonSet.
You would generally taint your node(s) like this:
kubectl taint nodes <your-node> key=value:IngressNodeThen on your PodSpec something like this:
tolerations:
- key: "key"
operator: "Equal"
value: "value"
effect: "IngressNode"It could also be because of missing labels on your node that your Pod needs in the nodeSelector field:
apiVersion: v1
kind: Pod
metadata:
name: nginx
labels:
env: test
spec:
containers:
- name: nginx
image: nginx
imagePullPolicy: IfNotPresent
nodeSelector:
cpuType: haswellThen on you'd add a label to your node.
kubectl label nodes kubernetes-foo-node-1 cpuType=haswellHope it helps!
