k8s部署apollo配置中心(无坑版)

部署环境

1、mysql 10.10.10.26
账户 root 密码 123
apollo-config内部地址10.43.22.22

一、创建数据

Apollo服务端共需要两个数据库:ApolloPortalDB和ApolloConfigDB,我们把数据库、表的创建和样例数据都分别准备了sql文件,只需要导入数据库即可。
1.创建ApolloPortalDB
通过各种MySQL客户端导入apolloportaldb.sql即可。
2.创建ApolloConfigDB
通过各种MySQL客户端导入apolloconfigdb.sql即可。

二、创建Secrets

apollo-config环境变量(dev)

apiVersion: v1
kind: Secret
metadata:
  name: apollo-config-secret
  namespace: default
type: Opaque
data:
  #SPRING_DATASOURCE_PASSWORD: 123
  SPRING_DATASOURCE_PASSWORD: MTIz
  #SPRING_DATASOURCE_URL: jdbc:mysql://10.10.10.26:30001/ApolloConfigDB?characterEncoding=utf8
  SPRING_DATASOURCE_URL: >-
    amRiYzpteXNxbDovLzEwLjEwLjEwLjI2OjMwMDAxL0Fwb2xsb0NvbmZpZ0RCP2NoYXJhY3RlckVuY29kaW5nPXV0Zjg=
  #SPRING_DATASOURCE_USERNAME: root
  SPRING_DATASOURCE_USERNAME: cm9vdA==

apollo-portal环境变量(dev)

apiVersion: v1
kind: Secret
metadata:
  name: apollo-portal-secret
  namespace: default
type: Opaque
data:
  #APOLLO_PORTAL_ENVS = dev
  APOLLO_PORTAL_ENVS: ZGV2
  #PRO_META = http://localhost:8080
  PRO_META: aHR0cDovL2xvY2FsaG9zdDo4MDgw
  #SPRING_DATASOURCE_PASSWORD = 123
  SPRING_DATASOURCE_PASSWORD: MTIz
  #SPRING_DATASOURCE_URL = jdbc:mysql://10.10.10.26:30001/ApolloPortalDB? characterEncoding=utf8
  SPRING_DATASOURCE_URL: >-
    amRiYzpteXNxbDovLzEwLjEwLjEwLjI2OjMwMDAxL0Fwb2xsb1BvcnRhbERCPyBjaGFyYWN0ZXJFbmNvZGluZz11dGY4
   #SPRING_DATASOURCE_USERNAME = root
  SPRING_DATASOURCE_USERNAME: cm9vdA==

三、创建配置文件ConfigMap

1.创建密文用于环境变量

apiVersion: v1
kind: ConfigMap
metadata:
  labels:
    name: apollo-portal-cfg-dev
  name: apollo-portal-cfg
  namespace: default
data:
  key-apollo-env.properties: |-
    local.meta=http://localhost:8080
    dev.meta=http://10.43.22.22:8080
    fat.meta=http://fill-in-fat-meta-server:8080
    uat.meta=http://fill-in-uat-meta-server:8080
    lpt.meta=${lpt_meta}
    pro.meta=http://fill-in-pro-meta-server:8080
  key-app.properties: |-
    appId=100003173
    jdkVersion=1.8
  key-application-github.properties: |-
    local.meta=http://localhost:8080
    dev.meta=http://fill-in-dev-meta-server:8080
    fat.meta=http://fill-in-fat-meta-server:8080
    uat.meta=http://fill-in-uat-meta-server:8080
    lpt.meta=${lpt_meta}
    pro.meta=http://fill-in-pro-meta-server:8080

四、部署ApolloConfig

1、创建内部访问service

apiVersion: v1
kind: Service
metadata:
  name: apollo-config-service-inner
  namespace: default
spec:
  selector:
    name: apollo-config-dev
  type: ClusterIP
  clusterIP: 10.43.22.22   #将该值写入ApolloConfigDB数据库eureka.service.url
  ports:
    - name: 
      port: 8080
      protocol: TCP
      targetPort: 8080
  sessionAffinity: None

2、部署服务

apiVersion: apps/v1
kind: Deployment
metadata:
  name: apollo-config
  namespace: default
spec:
  selector:
    matchLabels:
      name: apollo-config-dev
  template:
    metadata:
      labels:
        name: apollo-config-dev
    spec:
      containers:
        - imagePullPolicy: IfNotPresent
          image: 'apolloconfig/apollo-configservice:latest'
          envFrom:
            - prefix: ''
              secretRef:
                name: apollo-config-secret
          ports:
            - name: 8080tcp
              expose: true
              protocol: TCP
              containerPort: 8080
          name: apollo-config

五、部署ApolloAdmin

1、配置数据库
更改配置ApolloConfigDB>ServerConfig>eureka.service.url = http://10.43.22.22:8080/eureka/

2、部署服务

apiVersion: apps/v1
kind: Deployment
metadata:
  name: apollo-admin
  namespace: default
spec:
  selector:
    matchLabels:
      name: apollo-admin-dev
  template:
    metadata:
      labels:
        name: apollo-admin-dev
    spec:
      containers:
        - imagePullPolicy: IfNotPresent
          image: 'apolloconfig/apollo-adminservice:latest'
          envFrom:
            - prefix: ''
              secretRef:
                name: apollo-config-secret
          ports:
            - name: 8090tcp
              expose: true
              protocol: TCP
              containerPort: 8090
          name: apollo-admin
      restartPolicy: Always
  replicas: 1

六、部署ApolloPortal

1、部署服务

apiVersion: apps/v1
kind: Deployment
metadata:
  name: apollo-portal
  namespace: default
spec:
  selector:
    matchLabels:
      name: apollo-portal-dev
  template:
    metadata:
      labels:
        name: apollo-portal-dev
    spec:
      containers:
        - imagePullPolicy: IfNotPresent
          image: 'apolloconfig/apollo-portal:latest'
          envFrom:
            - prefix: ''
              secretRef:
                name: apollo-portal-secret
          ports:
            - name: 8070tcp
              expose: true
              protocol: TCP
              containerPort: 8070
          name: apollo-portal
          volumeMounts:
          - name: apollo-portal-cfg-volume
            mountPath: /apollo-portal/config/
      restartPolicy: Always
      volumes:
      - name: apollo-portal-cfg-volume
        configMap:
         name: apollo-portal-cfg
         items:
         - key: key-application-github.properties
           path: application-github.properties
         - key: key-apollo-env.properties
           path: apollo-env.properties
         - key: key-app.properties
           path: app.properties
  replicas: 1
