K8S 创建 Pod 状态状态一直处在 Pending 状态

# oc get pods
NAME                       READY     STATUS    RESTARTS   AGE
hello-openshift-1-deploy   0/1       Pending   0          49s

# oc describe pod hello-openshift-1-deploy
……

    SecretName:  deployer-token-tcb2q

查看 Node 节点标签

# oc describe node node1.example.com
Name:               node1.example.com
Roles:              infra
Labels:             beta.kubernetes.io/arch=amd64
                          beta.kubernetes.io/os=linux
                          kubernetes.io/hostname=node1.example.com
                          node-role.kubernetes.io/infra=true
Annotations:        node.openshift.io/md5sum=d9c516f9df26b5c0d1dfacc45ddb325f

查询发现没有需要的标签

给 Node 节点打所需的标签

# oc label node node1.example.com  node-role.kubernetes.io/compute=true
# oc label node node2.example.com  node-role.kubernetes.io/compute=true

再次查看 Pod 状态

# oc get pods
NAME                       READY     STATUS              RESTARTS   AGE
hello-openshift-1-deploy   0/1       ContainerCreating   0          18m

过会后再次查看

# oc get pods
NAME                      READY     STATUS    RESTARTS   AGE
hello-openshift-1-5hqc2   1/1       Running   0          22m

问题完美解决！！！
