云计算基础架构平台应用 项目11-Kubernetes 搭建与运维.ppt

项目实施 可以看到前面创建的Deployment给我们创建了一个Pod 查看Default命名空间下所有资源： [root@k8s-master ~]# kubectl get all NAME READY STATUS RESTARTS AGE pod/nignx-5f5ff5b8bc-8cfzf 1/1 Running 0 4m20s ? NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE service/kubernetes ClusterIP none 443/TCP 21h ? NAME READY UP-TO-DATE AVAILABLE AGE deployment.apps/nignx 1/1 1 1 4m20s ? NAME DESIRED CURRENT READY AGE replicaset.apps/nignx-5f5ff5b8bc 1 1 1 4m20s 前面创建的Nginx Deployment也帮我们创建了一个Replicaset，Replicaset控制着Pod的副本数，Replicaset(简称RS) 项目实施 5、查看资源的详细信息： 查看K8s-Node节点的详细信息 [root@k8s-master ~]# kubectl describe nodes k8s-node Name: k8s-node Roles: none Labels: beta.kubernetes.io/arch=amd64 beta.kubernetes.io/os=linux kubernetes.io/arch=amd64 kubernetes.io/hostname=k8s-node kubernetes.io/os=linux 项目实施 查看Nginx Deployment的详细信息 [root@k8s-master ~]# kubectl describe pod nignx-5f5ff5b8bc-8cfzf Events: Type Reason Age From Message Normal Scheduled 8m59s default-scheduler Successfully assigned default/nignx-5f5ff5b8bc-8cfzf to k8s-node Normal Pulled 8m58s kubelet, k8s-node Container image nginx already present on machine Normal Created 8m58s kubelet, k8s-node Created container nignx Normal Started 8m58s kubelet, k8s-node Started container nignx 我们在这个Events里面可以看到，首先Pod经过调度器调度到K8s-Node节点，然后Kubelet拉取镜像，创建Nginx容器，到启动完成。 项目实施 6、删除资源： 删除Pod [root@k8s-master ~]# kubectl delete pods nignx-5f5ff5b8bc-8cfzf pod nignx-5f5ff5b8bc-8cfzf deleted [root@k8s-master ~]# kubectl get pods NAME READY STATUS RESTARTS AGE nignx-5f5ff5b8bc-4rf8v 1/1 Running 0 2m27s 前面说了如果Pod意外
