1、ruoyi-pro后端打包jar

mvn clean install -U -DskipTests

生成.jar包

yudao-server20260716.jar

本地可以先选行一下

java -jar  yudao-server20260716.jar

2、yudao-server20260716.jar 生成镜像

2.1 DockerFile 文件内容如下

## 基础镜像
FROM eclipse-temurin:25-jre

## 创建工作目录
RUN mkdir -p /yudao-server
WORKDIR /yudao-server

## 关键修改：直接复制当前目录下的完整jar文件名
COPY ./yudao-server20260716.jar app.jar

## 时区、JVM参数不变
ENV TZ=Asia/Shanghai
ENV JAVA_OPTS="-Xms512m -Xmx512m -Djava.security.egd=file:/dev/./urandom"
ENV ARGS=""

## 暴露端口
EXPOSE 48080

## 启动命令
ENTRYPOINT ["sh","-c","java $JAVA_OPTS -jar app.jar $ARGS"]

2.2  生成镜像

docker build -t yudao-server:20260716 .

2.3  镜像yudao-server:20260716  保存为tar文件

docker save yudao-server:20260716 -o yudao-server20260716.tar

2.4 tar 文件复制到  master(192.168.91.166),node2(192.168.91.167),node3(192.168.91.168)

yudao-server20260716.tar

scp yudao-server20260716.tar root@192.168.91.166:/root/

scp yudao-server20260716.tar root@192.168.91.167:/root/

scp yudao-server20260716.tar root@192.168.91.168:/root/

2.5 master(192.168.91.166),node2(192.168.91.167),node3(192.168.91.168)

     把yudao-server20260716.tar  导入镜像

     docker load -i /root/yudao-server20260716.tar

3、创建Deployment、Service文件yaml

kubeSphere 用命令创建 namespace: biz-rouyi

   【Deployment、Service】rouyi-ng-biz.yaml内容如下

apiVersion: apps/v1
kind: Deployment
metadata:
  name: rouyi-ng-biz
  namespace: biz-rouyi
spec:
  replicas: 1
  selector:
    matchLabels:
      app: rouyi-ng-biz
  template:
    metadata:
      labels:
        app: rouyi-ng-biz
    spec:
      # 本地镜像无需拉取密钥，删除 imagePullSecrets
      containers:
        - name: yudao-server
          # 替换为本地导入的镜像标签
          image: yudao-server:20260716
          #imagePullPolicy: Never
          ports:
            - containerPort: 48080
          env:
            - name: SPRING_PROFILES_ACTIVE
              value: "local"
          resources:
            requests:
              memory: "512Mi"
              cpu: "500m"
            limits:
              memory: "1Gi"
              cpu: "1000m"
---
apiVersion: v1
kind: Service
metadata:
  name: rouyi-ng-biz
  namespace: biz-rouyi
spec:
  type: NodePort
  selector:
    app: rouyi-ng-biz
  ports:
    - port: 48080
      targetPort: 48080
      nodePort: 30081  #对外爆露端口

4、发布【Deployment、Service】

kubectl apply -f rouyi-ng-biz.yaml -n biz-rouyi

查看kubectl get pods -n  biz-rouyi

查看kubectl  deployment日志

kubectl logs -f deployment/rouyi-ng-biz -n biz-rouyi
