Openshift 創建 Pod 狀態狀態一直處在 Pending 狀態
# 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 Optional: false QoS Class: BestEffort Node-Selectors: node-role.kubernetes.io/compute=true Tolerations: <none> Events: Type Reason Age From Message ---- ------ ---- ---- ------- Warning FailedScheduling 3s (x8 over 1m) default-scheduler 0/3 nodes are available: 3 node(s) didn't match node selector.
查看 Node 節點標籤
# 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 ……
查詢發現沒有需要的標籤
給 Node 節點打所需的標籤
# 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 狀態
# oc get pods NAME READY STATUS RESTARTS AGE hello-openshift-1-deploy 0/1 ContainerCreating 0 18m
過會後再次查看
# oc get pods NAME READY STATUS RESTARTS AGE hello-openshift-1-5hqc2 1/1 Running 0 22m
問題完美解決！！！
