kubernate部署服务

系统环境

1. 创建 nameSpace和 configMap

vim demo-ns.yaml

apiVersion: v1
kind: Namespace
metadata:
  name: demo
  labels:
    name: demo
---
apiVersion: v1
kind: ConfigMap
metadata:
  name: demo-cm
  namespace: demo
data:
  application-local.yml: |
    server:
        port: 9195
        address: 0.0.0.0
    spring:
        main:
            allow-bean-definition-overriding: true
        application:
            name: shenyu-bootstrap
    management:
        health:
            defaults:
            enabled: false
    shenyu:
        local:
            enabled: true
        file:
            enabled: true
        cross:
            enabled: true
        dubbo:
            parameter: multi
        sync:
            websocket:
              urls: ws://shenyu-admin-svc.shenyu.svc.cluster.local:9095/websocket
        exclude:
            enabled: false
            paths:
            - /favicon.ico
        extPlugin:
            enabled: true
            threads: 1
            scheduleTime: 300
            scheduleDelay: 30
        scheduler:
            enabled: false
            type: fixed
            threads: 16
    logging:
        level:
            root: info
            org.springframework.boot: info
            org.apache.ibatis: info
            org.apache.shenyu.bonuspoint: info
            org.apache.shenyu.lottery: info
            org.apache.shenyu: info
  application-mysql.yml: |
    spring.datasource.url: jdbc:mysql://mysql.shenyu.svc.cluster.local:3306/shenyu?useUnicode=true&characterEncoding=utf-8&useSSL=false
    spring.datasource.username: root
    spring.datasource.password: 123456

2. 创建 endpoint 代理外部 mysql

demo-mysql-service

kind: Service
apiVersion: v1
metadata:
  name: mysql
  namespace: shenyu
spec:
  ports:
  - port: 3306
    name: mysql
    targetPort: 3306
---
kind: Endpoints
apiVersion: v1
metadata:
  name: mysql
  namespace: shenyu
subsets:
- addresses:
  - ip: 10.10.10.88
  ports:
  - port: 3306
    name: mysql

3.创建 pv和pvc 存储

    vim demo-store.yaml

# 示例使用 pvc、pv、storageClass 来存储文件
apiVersion: v1
kind: PersistentVolume
metadata:
  name: demo-pv
spec:
  capacity:
    storage: 1Gi
  volumeMode: Filesystem
  accessModes:
  - ReadWriteOnce
  persistentVolumeReclaimPolicy: Delete
  storageClassName: local-storage
  local:
    path: /home/demo/k8s-pv  # 指定节点上的目录,该目录下面需要包含 mysql-connector.jar
  nodeAffinity:
    required:
      nodeSelectorTerms:
      - matchExpressions:
        - key: kubernetes.io/hostname
          operator: In
          values:
          - node1 # 指定节点
---
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: demo-pvc
  namespace: demo
spec:
  accessModes:
  - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi
  storageClassName: local-storage
---
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: local-storage
provisioner: kubernetes.io/no-provisioner
volumeBindingMode: WaitForFirstConsumer

4. 部署 应用程序boot-demo

# 示例使用 nodeport 方式暴露端口
apiVersion: v1
kind: Service
metadata:
  namespace: demo
  name: demo-svc
spec:
  selector:
    app: boot-bootstrap
  type: NodePort
  ports:
  - protocol: TCP
    port: 9195
    targetPort: 9195
    nodePort: 31195
---
# shenyu-bootstrap
apiVersion: apps/v1
kind: Deployment
metadata:
  namespace: shenyu
  name: shenyu-bootstrap
spec:
  selector:
    matchLabels:
      app: shenyu-bootstrap
  replicas: 1
  template:
    metadata:
      labels:
        app: shenyu-bootstrap
    spec:
      volumes:
      - name: shenyu-bootstrap-config
        configMap:
          name: shenyu-cm
          items:
          - key: application-local.yml
            path: application-local.yml
      containers:
      - name: shenyu-bootstrap
        image: apache/shenyu-bootstrap:latest
        ports:
        - containerPort: 9195
        env:
        - name: TZ
          value: Asia/Beijing
        volumeMounts:
        - name: shenyu-bootstrap-config
          mountPath: /opt/shenyu-bootstrap/conf/application-local.yml
          subPath: application-local.yml
