K8s部署

本文介绍使用 K8s 来部署 Apache ShenYu 网关。

一. 使用 h2 作为数据库

1. 创建 Namespace和 ConfigMap2. 部署 shenyu-admin3. 部署 shenyu-bootstrap

二. 使用 MySQL 作为数据库

和 h2 过程类似，需要注意的两个地方
1. 需要加载 mysql-connector.jar，所以需要一个文件存储的地方2. 需要指定外部 MySQL 数据库配置，通过 Endpoints 来代理外部 MySQL 数据库
具体流程如下：
1. 创建 Namespace和 ConfigMap2. 创建 Endpoints 代理外部 MySQL3. 创建 PV 存储 mysql-connector.jar4. 部署 shenyu-admin5. 部署 shenyu-bootstrap

一. 使用 h2 作为数据库#

1. 创建 Namespace 和 ConfigMap#

创建文件 shenyu-ns.yaml

apiVersion: v1kind: Namespacemetadata:  name: shenyu  labels:    name: shenyu---apiVersion: v1kind: ConfigMapmetadata:  name: shenyu-cm  namespace: shenyudata:  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

执行 kubectl apply -f shenyu-ns.yaml

2. 部署 shenyu-admin#

创建文件 shenyu-admin.yaml

# 示例使用 nodeport 方式暴露端口apiVersion: v1kind: Servicemetadata:  namespace: shenyu  name: shenyu-admin-svcspec:  selector:    app: shenyu-admin  type: NodePort  ports:  - protocol: TCP    port: 9095    targetPort: 9095    nodePort: 31095---# shenyu-adminapiVersion: apps/v1kind: Deploymentmetadata:  namespace: shenyu  name: shenyu-adminspec:  selector:    matchLabels:      app: shenyu-admin  replicas: 1  template:    metadata:      labels:        app: shenyu-admin    spec:      containers:      - name: shenyu-admin        image: apache/shenyu-admin:2.4.0        imagePullPolicy: Always        ports:        - containerPort: 9095        env:        - name: 'TZ'          value: 'Asia/Beijing'

执行kubectl apply -f shenyu-ns.yaml

3. 部署 shenyu-bootstrap#

创建文件 shenyu-bootstrap.yaml

# 示例使用 nodeport 方式暴露端口apiVersion: v1kind: Servicemetadata:  namespace: shenyu  name: shenyu-bootstrap-svcspec:  selector:    app: shenyu-bootstrap  type: NodePort  ports:  - protocol: TCP    port: 9195    targetPort: 9195    nodePort: 31195---# shenyu-bootstrapapiVersion: apps/v1kind: Deploymentmetadata:  namespace: shenyu  name: shenyu-bootstrapspec:  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:2.4.0        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

执行 kubectl apply -f shenyu-bootstrap.yaml
