|NO.Z.00282|——————————|^^ 部署 ^^|——|KuberNetes&运维.V04|——|EFK架构.v04|部署Kibana|

一、部署Kibana

### --- 创建Kibana-service.yaml文件

[root@k8s-master01 EFK]# cat kibana-service.yaml 
apiVersion: v1
kind: Service
metadata:
  name: kibana-logging
  namespace: public-service
  labels:
    k8s-app: kibana-logging
    kubernetes.io/cluster-service: "true"
    addonmanager.kubernetes.io/mode: Reconcile
    kubernetes.io/name: "Kibana"
spec:
  ports:
  - port: 5601
    protocol: TCP
    targetPort: ui
  selector:
    k8s-app: kibana-logging
  type: NodePort

二、创建Kibana-service

### --- 创建Kibana-service

[root@k8s-master01 EFK]# kubectl create -f kibana-service.yaml 
service/kibana-logging created

### --- 查看创建的kibana-service

[root@k8s-master01 EFK]# kubectl get svc -n public-service -owide
NAME                    TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)          AGE     SELECTOR
elasticsearch-logging   ClusterIP   10.107.157.176   <none>        9200/TCP         3h39m   k8s-app=elasticsearch-logging
kibana-logging          NodePort    10.97.92.222     <none>        5601:30495/TCP   147m    k8s-app=kibana-logging

### --- 查看创建的kibana-ep

[root@k8s-master01 EFK]# kubectl get ep -n public-service -owide
NAME                    ENDPOINTS            AGE
elasticsearch-logging   172.27.14.195:9200   3h38m
kibana-logging          172.17.125.6:5601    146m

三、创建Kibana-deployment.yaml资源文件

### --- 创建Kibana-deployment的配置文件

[root@k8s-master01 EFK]# cat kibana.yaml 
apiVersion: apps/v1
kind: Deployment
metadata:
  name: kibana-logging
  namespace: public-service
  labels:
    k8s-app: kibana-logging
    addonmanager.kubernetes.io/mode: Reconcile
spec:
  replicas: 1
  selector:
    matchLabels:
      k8s-app: kibana-logging
  template:
    metadata:
      labels:
        k8s-app: kibana-logging
      annotations:
        seccomp.security.alpha.kubernetes.io/pod: 'docker/default'
    spec:
      containers:
      - name: kibana-logging
        image: docker.elastic.co/kibana/kibana-oss:7.2.0
        resources:
          # need more cpu upon initialization, therefore burstable class
          limits:
            cpu: 1000m
          requests:
            cpu: 100m
        env:
          - name: ELASTICSEARCH_HOSTS
            value: http://elasticsearch-logging:9200
          - name: SERVER_NAME
            value: kibana-logging
          #- name: SERVER_BASEPATH
          #  value: /api/v1/namespaces/public-service/services/kibana-logging/proxy
          - name: SERVER_REWRITEBASEPATH
            value: "false"
        ports:
        - containerPort: 5601
          name: ui
          protocol: TCP
        livenessProbe:
          httpGet:
            path: /api/status
            port: ui
          initialDelaySeconds: 5
          timeoutSeconds: 10
        readinessProbe:
          httpGet:
            path: /api/status
            port: ui
          initialDelaySeconds: 5
          timeoutSeconds: 10

### --- 注：

~~~     # 注释一：副本数量为1
spec:
  replicas: 1
  selector:
    matchLabels:
      k8s-app: kibana-logging

~~~     # 注释二：es地址
~~~     kibana连接es的地址；若是外部地址的话，可以将外部和地址映射到service上，
~~~     然后写上service地址即可

        env:
          - name: ELASTICSEARCH_HOSTS
            value: http://elasticsearch-logging:9200    

~~~     # 注释三：安装路径
~~~     此环境是通过service访问的，需要把这行内容注销掉，不然他会通过这个地址去访问

          #- name: SERVER_BASEPATH                      
          #  value: /api/v1/namespaces/public-service/services/kibana-logging/proxy

四、创建Kibana-deployment

### --- 创建Kibana-deployment

[root@k8s-master01 EFK]# kubectl create -f kibana.yaml 
deployment.apps/kibana-logging created

### --- 查看创建的Kibana

[root@k8s-master01 EFK]# kubectl get po -n public-service -owide
NAME                              READY   STATUS    RESTARTS   AGE   IP               NODE           NOMINATED NODE   READINESS GATES
elasticsearch-logging-0           1/1     Running   0          63m   172.27.14.195    k8s-node02     <none>           <none>
fluentd-es-v3.0.1-xprsz           1/1     Running   2          48m   172.17.125.4     k8s-node01     <none>           <none>

### --- 查看创建的Kibana的端口号

[root@k8s-master01 EFK]# kubectl get po,svc,ep -n public-service -owide
NAME                                  READY   STATUS    RESTARTS   AGE     IP              NODE         NOMINATED NODE   READINESS GATES
