写在前面：

若依（RuoYi）Cloud 是一套基于 Spring Cloud、Spring Boot、Vue 等技术栈构建的开源微服务权限管理系统，功能完整、结构清晰，广泛应用于企业级后台系统开发。在实际使用中，将 RuoYi-Cloud 部署到 Kubernetes 上，不仅可以实现微服务的高可用、自动扩缩、统一管理，还能配合 CI/CD 实现持续交付，极大提升开发运维效率。

本篇博客将详细介绍如何通过编写 YAML 文件的方式，将 RuoYi-Cloud 从中间件到业务模块逐步部署到 Kubernetes 集群中，包括 MySQL、Redis、Nacos等中间件的部署配置，以及各个微服务的启动管理等。适合有一定 K8s 基础，希望将若依微服务架构进行容器化部署的开发者与运维人员参考使用，本文分为上下两篇，上篇主要讲解各个中间件的部署，下面主要讲解各个应用服务的部署。

2. 部署中间件

部署 MySQL

--- 1. 目录结构准备
mysql
├── configmap.yaml         ## 用于挂载my.cnf的配置文件
├── deployment.yaml        ## 使用deployment 控制器
├── pvc.yaml               ## 数据卷持久化
└── service.yaml           ## 暴露端口，用于测试
--- 2. 部署pvc,这里我使用nfs挂载存储,自行准备nfs共享目录哦
apiVersion: v1
kind: PersistentVolume
metadata:
  name: mysql-pv
  labels:
   apps: mysql
spec:
  accessModes:
  - ReadWriteMany
  nfs:
   ## NFS的服务端地址和共享路径
   server: 192.168.0.160
   path: /data/nfs/mysql
  persistentVolumeReclaimPolicy: Retain
  capacity: 
    storage: 5Gi
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: mysql-pvc
  labels:
    apps: mysql
spec:
  accessModes:
  - ReadWriteMany
  resources:
    requests:
      storage: 2Gi
  volumeName: mysql-pv
--- 3. 部署configmap,这里是为了挂载数据库的配置文件,可以自行修改my.cnf的内容
apiVersion: v1
kind: ConfigMap
metadata:
  name: mysql-config 
data:
  ## 初始化数据库
  MYSQL_ROOT_PASSWORD: "123456"
  MYSQL_DATABASE: "ry-cloud"
  my.cnf: |-
   [client]
   default-character-set=utf8mb4 
   [mysql]
   default-character-set=utf8mb4
   [mysqld]
   init_connect='SET collation_connection = utf8mb4_unicode_ci'
   init_connect='SET NAMES utf8mb4'
   character-set-server=utf8mb4
   collation-server=utf8mb4_unicode_ci
   skip-character-set-client-handshake
   skip-name-resolve
--- 4. 部署deployment 
apiVersion: apps/v1
kind: Deployment
metadata: 
  name: mysql-deployment
spec:
  replicas: 1
  selector: 
    matchLabels:
      apps: mysql
  template:
    metadata:
      labels:
        apps: mysql
    spec:
     volumes:
     - name: mysql-storage
       persistentVolumeClaim:
        claimName: mysql-pvc
     - name: mysql-config
       configMap:
        name: mysql-config
     containers:
     - name: mysql
       ## 这里的镜像使用我自己的私有仓库
       image: 192.168.0.77:32237/uat/mysql:8.0.32-oracle
       ports:
        - containerPort: 3306
       env:
       - name: MYSQL_ROOT_PASSWORD
         valueFrom:
          configMapKeyRef:
            name: mysql-config
            key: MYSQL_ROOT_PASSWORD
       - name: MYSQL_DATABASE
         valueFrom:
          configMapKeyRef:
            name: mysql-config
            key: MYSQL_DATABASE
       volumeMounts:
       - name: mysql-storage
         mountPath: /var/lib/mysql
       - name: mysql-config
         mountPath: /etc/mysql/conf.d/my.cnf
         subPath: my.cnf
--- 5. 部署service,这里我用nodePort暴露端口便于测试
apiVersion: v1
kind: Service
metadata:
  name: mysql-service 
spec: 
  selector:
    apps: mysql
  type: NodePort
  ports:
  - port: 3306
    targetPort: 3306
    protocol: TCP
    nodePort: 30084

     containers:
     - name: redis
       image: 192.168.0.77:32237/uat/redis:6.2.18-alpine
       ports:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nacos
spec:
  replicas: 1
  selector:
    matchLabels:
      app: nacos
  template:

        persistentVolumeClaim:
          claimName: nacos-pvc
      - name: nacos-config
        configMap:
          name: nacos-config
      containers:
      - name: nacos
        ## 注意nacos 镜像版本
        image: 192.168.0.77:32237/uat/nacos:2.1.0 
        ports:
        - containerPort: 8848

          ## 配置文件挂载位置
          mountPath: /home/nacos/conf/application.properties 
          subPath: application.properties
--- 5. 部署service
apiVersion: v1
kind: Service
metadata:
  name: nacos-service 
spec: 
  selector:
    app: nacos
  type: NodePort
  ports:
  - port: 8848
    targetPort: 8848
    protocol: TCP
    nodePort: 30086

浏览器访问：IP地址:30086/nacos

克隆dev环境到prod名称空间中

注意：

提前修改nacos线上配置，确认好每个中间件的连接地址是否正确

nacos配置文件中的中间件例如redis、mysql等链接地址一定是集群内的访问地址
