一，准备工作：

1，k8s环境

2，nfs服务器

二，创建PV

nfs_pv.yaml

apiVersion: v1
kind: PersistentVolume
metadata:
  name: kingsun.nfs1
spec:
  capacity:
    storage: 1Gi
  accessModes: ["ReadWriteMany","ReadWriteOnce","ReadOnlyMany"]
  persistentVolumeReclaimPolicy: Recycle
  storageClassName: nfs
  nfs:
    path: /mnt/nfsdata
    server: 196.1.210.140

---
apiVersion: v1
kind: PersistentVolume
metadata:
  name: kingsun.nfs2
spec:
  capacity:
    storage: 1Gi
  accessModes: ["ReadWriteMany","ReadWriteOnce","ReadOnlyMany"]
  persistentVolumeReclaimPolicy: Recycle
  storageClassName: nfs
  nfs:
    path: /mnt/nfsdata
    server: 196.1.210.140
---
apiVersion: v1
kind: PersistentVolume
metadata:
  name: kingsun.nfs3
spec:
  capacity:
    storage: 1Gi
  accessModes: ["ReadWriteMany","ReadWriteOnce","ReadOnlyMany"]
  persistentVolumeReclaimPolicy: Recycle
  storageClassName: nfs
  nfs:
    path: /mnt/nfsdata
    server: 196.1.210.140

执行：kubectl apply -f nfs_pv.yaml 创建pv(PersistentVolume)

三，将Consul使用端口通过Service暴露

PortService.yaml

apiVersion: v1
kind: Service
metadata:  
    name: consul  
    labels:    
      name: consul
spec:  
    type: ClusterIP
    clusterIP: None  
    ports:    
      - name: http      
        port: 8500      
        targetPort: 8500    
      - name: https      
        port: 8443      
        targetPort: 8443    
      - name: rpc      
        port: 8400      
        targetPort: 8400    
      - name: serflan-tcp      
        protocol: "TCP"      
        port: 8301      
        targetPort: 8301    
      - name: serflan-udp      
        protocol: "UDP"      
        port: 8301      
        targetPort: 8301    
      - name: serfwan-tcp      
        protocol: "TCP"      
        port: 8302      
        targetPort: 8302    
      - name: serfwan-udp      
        protocol: "UDP"      
        port: 8302      
        targetPort: 8302    
      - name: server      
        port: 8300      
        targetPort: 8300    
      - name: consuldns      
        port: 8600      
        targetPort: 8600  
    selector:    
     app: consul

四，编辑ACL配置文件并保存到K8S ConfigMap

Acl.json

{"acl":{
 "enabled":true,
 "default_policy":"deny",
 "enable_token_persistence":true,
 "tokens":{
   "master":"8dc1eb67-1f5f-4e10-ad9d-5e58b047647c",
   "agent":"8dc1eb67-1f5f-4e10-ad9d-5e58b047647c"
 }
}}

执行：kubectl create configmap --from-file Acl.json

查看configmap：kubectl get configmap -o yaml

PS G:KingSunConsulYaml> kubectl get configmap -o yaml
apiVersion: v1
items:
- apiVersion: v1
  data:
    Acl.json: "{"acl":{
 "enabled":true,
 "default_policy":"deny",

      "enable_token_persistence":true,
 "tokens":{
   "master":"8dc1eb67-1f5f-4e10-ad9d-5e58b047647c",

        "agent":"8dc1eb67-1f5f-4e10-ad9d-5e58b047647c"
 }
}}"
  kind: ConfigMap
  metadata:
    creationTimestamp: "2019-12-03T08:21:22Z"
    name: consul-acl-config
    namespace: default
    resourceVersion: "771714"
    selfLink: /api/v1/namespaces/default/configmaps/consul-acl-config
    uid: 57507410-e0a2-4979-9c8b-731fe9dc62b8
kind: List
metadata:
  resourceVersion: ""
  selfLink: ""

五，编辑StateFulSet配置文件创建pod

StateFulSet.yaml

apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: consul
spec:
  selector: 
    matchLabels:
      app: consul
  serviceName: consul
  replicas: 1
  template: 
    metadata:
      labels:
        app: consul
    spec:
      #affinity:
      #  podAntiAffinity:
      #    requiredDuringSchedulingIgnoredDuringExecution:
      #      - labelSelector:
      #          matchExpressions:
      #            - key: app
      #              operator: In
      #              values:
      #                - consul
      #        topologyKey: kubernetes.io/hostname
      terminationGracePeriodSeconds: 10
      volumes:
        - name: config
          configMap:
            name: consul-acl-config
      containers:
      - name: consul
        image: consul:latest
        volumeMounts:
         - name: config
           mountPath: /consul/config
         - name: data
           mountPath: /consul/data
        command: 
        - "/bin/sh"
        - "-ec"
        - |
          exec /bin/consul agent 
           -server 
           -ui 
           -advertise="$(PODIP)" 
           -bind=0.0.0.0 
           -client=0.0.0.0 
           -bootstrap-expect=1 
           -data-dir=/consul/data 
           -domain=cluster.local 
           -retry-join=consul-0.consul.$(NAMESPACE).svc.cluster.local 
           -disable-host-node-id 
           -datacenter=ks 
           -config-file=/consul/config/Acl.json
        env:
            - name: PODIP
              valueFrom:
                fieldRef:
                  fieldPath: status.podIP
            - name: NAMESPACE
              valueFrom:
                fieldRef:
                  fieldPath: metadata.namespace
        ports:
            - containerPort: 8500
              name: ui-port
            - containerPort: 8400
              name: alt-port
            - containerPort: 53
              name: udp-port
            - containerPort: 8443
              name: https-port
            - containerPort: 8080
              name: http-port
            - containerPort: 8301
              name: serflan
            - containerPort: 8302
              name: serfwan
            - containerPort: 8600
              name: consuldns
            - containerPort: 8300
              name: server
  volumeClaimTemplates:
    - metadata:
       name: data
      spec:
       accessModes: ["ReadWriteOnce"]
       resources:
         requests:
           storage: 1Gi
       storageClassName: nfs

执行：kubectl apply -f StateFulSet.yaml

查看consul pod日志：kubectl logs consul-0

查看StateFulSet启动日志：kubectl describe StateFulSet consul

六，通过NodePort Service暴露consul ui

UiService.yaml

apiVersion: v1
kind: Service
metadata:
  name: consul-ui
  labels:
    app: consul
spec:
  selector:
     app: consul
  ports:
   - name: consul-port
     protocol: TCP
     port: 80
     nodePort: 32000
     targetPort: 8500
  type: NodePort

七，打开ui

先点击"acl"输入Acl.json中定义的master_token
