Statefulset说明: 为了解决有状态服务的部署,例如mysql的主从等 pod拥有唯一且固定的名称 按照顺序对pod进行启停、伸缩和回收 Headless Services(无头服务)请求直接解析到pod的ip上 参考链接:https://kubernetes.io/zh-cn/docs/concepts/workloads/controllers/statefulset/ yaml文件示例: apiVersion: apps/v1 kind: StatefulSet metadata: name: nginx-sts namespace: wyh-test1-ns labels: app: nginx-sts spec: replicas: 1 selector: matchLabels: app: nginx-sts-pod serviceName: nginx-svc template: metadata: labels: app: nginx-sts-pod spec: containers: - name: nginx-sts-pod image: nginx imagePullPolicy: IfNotPresent ports: - containerPort: 80 --- apiVersion: v1 kind: Service metadata: name: nginx-svc namespace: wyh-test1-ns labels: app: nginx-svc spec: type: ClusterIP clusterIP: None ports: - name: http port: 80 targetPort: 80 selector: app: nginx-sts-pod 运行文件: kubectl apply -f nginx-statefulset.yaml 增加到三个节点: kubectl scale --replicas=3 sts nginx-sts -nwyh-test1-ns 无头service: ################################################################################################ DeamonSet简介: 在当前每个节点运行同一个pod,当有新节点加入集群时,也会在新节点运行相同的pod,当节点从集群中移除时,其pod也会被回收且不会在其他机器上重建 参考链接:https://kubernetes.io/zh-cn/docs/concepts/workloads/controllers/daemonset/ yaml文件示例(信任了master的污点,会在master节点运行pod): apiVersion: apps/v1 kind: DaemonSet metadata: name: nginx-ds namespace: wyh-test1-ns labels: app: nginx-ds spec: selector: matchLabels: app: nginx-ds-pod template: metadata: labels: app: nginx-ds-pod spec: #污点信任 tolerations: - effect: NoSchedule key: node.kubernetes.io/unschedulable operator: Exists hostNetwork: true #使用宿主机网络(如果此nginx是访问入口,那么使用hostnetwork性能会更好) hostPID: true #使用宿主机进程 containers: - name: nginx-ds-pod image: nginx imagePullPolicy: IfNotPresent ports: - containerPort: 80 --- apiVersion: v1 kind: Service metadata: name: nginx-svc namespace: wyh-test1-ns labels: app: nginx-svc spec: type: ClusterIP ports: - name: http port: 80 targetPort: 80 selector: app: nginx-ds-pod 运行文件: kubectl apply -f nginx-deamonset.yaml 查看节点运行情况(192.168.213.11是master): kubectl get pod -A -owide | grep nginx-ds
