一.StatefulSet概述
1>.StatefulSet与Operator的关系
管理一组有状态pod服务的部署(deployment)和扩展(scaling)，并保证这些pod的顺序和唯一性。 与部署一样，StatefulSet管理基于相同容器规范的pod。 与部署不同，statefulSet为每个pod维护一个粘性标识。这些pod是从同一个规范创建的，但不能互换：每个pod都有一个peristent标识符，可以在任何重新调度中维护。 事实上，使用StatefulSet可以很轻松的帮咱们完成部署，但是扩展的话需要我们自己编写封装扩容集群或者缩容集群脚本代码的程序,这个程序我们统称为Operator。而且我们编写的脚本还需要进行大量测试，否则出现任意一个bug，将会在线上带来不堪设想的后果。 于是,有一家公司叫CoreOS的公司对StatefulSet进行二次封装开源了Operator SDK(Software Development Kit)接口，用户可以借助于Operator SDK的API比较轻松定制出Operator控制器。 这意味着第三方的程序员再去开发云原生应用不是针对Kubernetes云原生API,而是针对CoreOS公司的Operator SDK。换句话说，Kubernetes的大本营被人开了一道后门,从后方侵入快速拿下一半的云原生领土，而这个领土的所属方叫CoreOS。而CoreOS已经是Redhat旗下的产品，而Redhat又是IBM旗下的产品。 在国外,微软(Microsoft)，亚马逊(Amazon)已经是云计算的领头羊了，而IBM作为一个老牌的基础设施公司虽说也有自己的云计算产品但影响力却远远不如前两者公司。因为大公司通常是很难接收革新的,它们有自己成熟的产品也有充分的市场份额，有一个其它产品时竞争对手时，它们通常把竞争对手视为眼中钉肉中刺，而不是拥抱和开发它们，IBM就错失了很多良机。IBM之所以愿意买RedHat，原因之一可能是因为红帽公司旗下的CoreOS公司。 IBM公司地位发展也给咱们运维人员一定的启发，这就好比你已经轻车熟路的使用K8S，突然间又出现了一个颠覆性的产品的苗头之后,你一定不是第一个愿意接收它的人，会有一种抵触心理，此时若很多人抱着开放的心胸去学习了该产品，恍然之间觉得自己的技能要被淘汰了不得不去学习的时候，那些先行者早已在这个行业称为巨头了。 目前大部分应用也有自己的Operator开源项目，比较火热的应用在Github有对应的开源地址。博主推荐阅读:https://github.com/operator-framework/awesome-operators。
2>.StatefulSet的应用场景
statefulset对于需要以下一项或多项的应用程序很有价值: (1)有唯一固定的网络标识符; (2)固定唯一的持久存储; (3)有序优雅的部署和扩展; (4)有序右眼的删除和终止; (5)有序自动的执行滚动更新； StatefulSet的限制条件(Limitations): (1)各Pod用到的存储卷必须使用由StorageClass动态供给给或由管理事先创建好的PV; (2)删除StatefulSet或缩减其规模导致Pod被删除时不应该自动删除(这个需要我们定义pvc指定其回收策略为"Retain")其存储卷以确保数据安全; (3)StatefulSet控制器依赖于一个事先存在的Headless Serivce对象实现Pod对象的持久，唯一的标识符配置;次Headless Service需要由用户手动配置。
3>.StatefulSet的Pod 标识符(Identity)
有序索引(Ordinal Index): 对于一个有N个副本的StatefulSet，StatefulSet中的每个Pod将被分配一个整数序数，从0到N-1，在这个集合上是唯一的。 稳定网络ID(Stabel Network ID): StatefulSet中的每个Pod都从StatefulSet的名称和Pod的序号派生其主机名。 StatefulSet可以使用无头服务(Headless Service)来控制其Pods的域。此服务管理的域的任务格式为:"$(service name).$(namespace).svc.cluster.local",其中“cluster.local”是群集域。 创建每个Pod时，它将获得一个匹配的DNS子域，其格式为:"$(podname).$(governing service domain)",其中governing service由StatefulSet上的serviceName字段定义。
4>.Pod管理策略(Management Policies)
在Kubernetes 1.7及更高版本中，StatefulSet允许您放宽其排序保证，同时通过其.spec.podManagementPolicay字段保持其唯一性和标识保证。 有序(OrderedReady)Pod管理(Management): OrderedReady pod management是statefulset的默认设置。换句话说,就是当一个Pod创建成功后再回去创建下一个Pod，即有序创建Pod。
并行的(Parallel)Pod管理(Management): 并行Pod管理告诉StatefulSet控制器并行启动或终止所有Pod，不要等到Pod运行并准备就绪或完全终止后再启动或终止另一个Pod。
5>.更新策略(Update Strategies)
在Kubernetes 1.7及更高版本中，StatefulSet的.spec.updateStrategy字段允许您配置和禁用StatefulSet中Pods的容器、标签、资源请求/限制和注释的自动滚动更新。 ON Delete: 由用户手动删除现有的Pod对象从而触发其更新过程。 Rolling Updates: 默认策略,它通过自动更新机制完成更新过程，启动更新过程时,它自动删除每个Pod对象并以新配置进行重建,更新顺序同删除StatefulSet时的逆向操作机制，一次删除并更新一个Pod对象。
可以通过指定.spec.update strategy.RollingUpdate.partition对RollingUpdate更新策略进行分区。
如果指定了分区，则当StatefulSet的.pec.template被更新时，序号大于或等于分区的所有pod都将被更新。
序号小于分区的所有pod都将不会更新，即使它们被删除，也将在以前的版本中重新创建。

三.使用StatefulSet部署etcd服务
StatefulSet(简称sts)可以做到简单的部署，扩容等功能，但是要涉及到比较复杂的功能比如数据备份等功能建议大家使用Operator。
1>.创建etcd的service资源
[root@master200.yinzhengjie.org.cn ~]# vim /yinzhengjie/data/k8s/manifests/basic/statefulset/etcd-services.yaml [root@master200.yinzhengjie.org.cn ~]# [root@master200.yinzhengjie.org.cn ~]# cat /yinzhengjie/data/k8s/manifests/basic/statefulset/etcd-services.yaml apiVersion: v1 kind: Service metadata: name: etcd labels: app: etcd annotations: # Create endpoints also if the related pod isn't ready service.alpha.kubernetes.io/tolerate-unready-endpoints: "true" spec: ports: - port: 2379 name: client - port: 2380 name: peer clusterIP: None selector: app: etcd-member --- apiVersion: v1 kind: Service metadata: name: etcd-client labels: app: etcd spec: ports: - name: etcd-client port: 2379 protocol: TCP targetPort: 2379 selector: app: etcd-member type: NodePort [root@master200.yinzhengjie.org.cn ~]# [root@master200.yinzhengjie.org.cn ~]#

3>.创建etcd的实例StatefulSet配置文件
[root@master200.yinzhengjie.org.cn ~]# cat /yinzhengjie/data/k8s/manifests/basic/statefulset/etcd-statefulset.yaml apiVersion: apps/v1 kind: StatefulSet metadata: name: etcd labels: app: etcd spec: serviceName: etcd # changing replicas value will require a manual etcdctl member remove/add # # command (remove before decreasing and add after increasing) replicas: 3 selector: matchLabels: app: etcd-member template: metadata: name: etcd labels: app: etcd-member spec: containers: - name: etcd image: "quay.io/coreos/etcd:v3.2.16" ports: - containerPort: 2379 name: client - containerPort: 2380 name: peer env: - name: CLUSTER_SIZE value: "3" - name: SET_NAME value: "etcd" volumeMounts: - name: data mountPath: /var/run/etcd command: - "/bin/sh" - "-ecx" - | IP=$(hostname -i) PEERS="" for i in $(seq 0 $((${CLUSTER_SIZE} - 1))); do PEERS="${PEERS}${PEERS:+,}${SET_NAME}-${i}=http://${SET_NAME}-${i}.${SET_NAME}:2380" done # start etcd.

四.使用StatefulSet部署zookeeper服务参考配置文件
[root@master200.yinzhengjie.org.cn ~]# cat /yinzhengjie/data/k8s/manifests/basic/statefulset/zk-sts.yaml apiVersion: v1 kind: Service metadata: name: zk-hs labels: app: zk spec: ports: - port: 2888 name: server - port: 3888 name: leader-election clusterIP: None selector: app: zk --- apiVersion: v1 kind: Service metadata: name: zk-cs labels: app: zk spec: ports: - port: 2181 name: client selector: app: zk --- apiVersion: policy/v1beta1 kind: PodDisruptionBudget metadata: name: zk-pdb spec: selector: matchLabels: app: zk maxUnavailable: 1 --- apiVersion: apps/v1 kind: StatefulSet metadata: name: zk spec: selector: matchLabels: app: zk serviceName: zk-hs replicas: 3 updateStrategy: type: RollingUpdate podManagementPolicy: Parallel template: metadata: labels: app: zk spec: affinity: podAntiAffinity: requiredDuringSchedulingIgnoredDuringExecution: - labelSelector: matchExpressions: - key: "app" operator: In values: - zk-hs topologyKey: "kubernetes.io/hostname" containers: - name: kubernetes-zookeeper image: gcr.io/google-containers/kubernetes-zookeeper:1.0-3.4.10 resources: requests: memory: "1Gi" cpu: "0.5" ports: - containerPort: 2181 name: client - containerPort: 2888 name: server - containerPort: 3888 name: leader-election command: - sh - -c - "start-zookeeper \ --servers=3 \ --data_dir=/var/lib/zookeeper/data \ --data_log_dir=/var/lib/zookeeper/data/log \ --conf_dir=/opt/zookeeper/conf \ --client_port=2181 \ --election_port=3888 \ --server_port=2888 \ --tick_time=2000 \ --init_limit=10 \ --sync_limit=5 \ --heap=512M \ --max_client_cnxns=60 \ --snap_retain_count=3 \ --purge_interval=12 \ --max_session_timeout=40000 \ --min_session_timeout=4000 \ --log_level=INFO" readinessProbe: exec: command: - sh - -c - "zookeeper-ready 2181" initialDelaySeconds: 10 timeoutSeconds: 5 livenessProbe: exec: command: - sh - -c - "zookeeper-ready 2181" initialDelaySeconds: 10 timeoutSeconds: 5 volumeMounts: - name: data mountPath: /var/lib/zookeeper securityContext: runAsUser: 1000 fsGroup: 1000 volumeClaimTemplates: - metadata: name: data spec: accessModes: [ "ReadWriteOnce" ] storageClassName: gluster-dynamic resources: requests: storage: 5Gi [root@master200.yinzhengjie.org.cn ~]# [root@master200.yinzhengjie.org.cn ~]#
