<p>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.</p>

<pre><code>kube-system   ingress-error-pages-56b4446784-crl85      0/1       Pending   0          1d
kube-system   ingress-error-pages-56b4446784-m7jrw      0/1       Pending   0          5d
</code></pre>

<p>I have kubernetes cluster with one master and one node running on debain9. I encounted this error during openstack installation on kubernetes. </p>

<p>Kubectl describe pod shows the event as below:</p>

<pre><code>Events:
Type     Reason            Age                 From              Message
----     ------            ----                ----               -------
Warning  FailedScheduling  2m (x7684 over 1d)  default-scheduler  0/2 nodes are available: 1 PodToleratesNodeTaints, 2 MatchNodeSelector.
</code></pre>

<p>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....</p>

<p>PS: I am running debian9, kube version: v1.9.2+coreos.0, Docker - 17.03.1-ce</p>

<p>Any help appreciated ....</p>

<p>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.</p>

<p>You would generally taint your node(s) like this:</p>

<pre><code>kubectl taint nodes &lt;your-node&gt; key=value:IngressNode
</code></pre>

<p>Then on your PodSpec something like this:</p>

<pre><code>tolerations:
- key: "key"
  operator: "Equal"
  value: "value"
  effect: "IngressNode"
</code></pre>

<p>It could also be because of missing labels on your node that your Pod needs in the <code>nodeSelector</code> field:</p>

<pre><code>apiVersion: v1
kind: Pod
metadata:
  name: nginx
  labels:
    env: test
spec:
  containers:
  - name: nginx
    image: nginx
    imagePullPolicy: IfNotPresent
  nodeSelector:
    cpuType: haswell
</code></pre>

<p>Then on you'd add a label to your node.</p>

<pre><code>kubectl label nodes kubernetes-foo-node-1 cpuType=haswell
</code></pre>

<p>Hope it helps!</p>
