k8s部署ruoyi

踩坑指南

提前安装nfs，共享目录为：/nfs/data
ruoyi 前后端分离版下载地址：https://gitee.com/y_project/RuoYi-Vue

创建命名空间

bash

kubectl create ns ruoyi

部署mysql

在nfs共享目录下创建init、data和logs，分别挂载mysql的初始化脚本、数据和日志(配置文件没有复杂的配置，就直接用configmap挂载)
shell
```
mkdir -p /nfs/data/mysql/init 
mkdir -p /nfs/data/mysql/data 
mkdir -p /nfs/data/mysql/logs
```
将ruoyi项目中的ry_20240629.sql和quartz.sql放到init目录下

创建资源文件 mysql-svc-deploy-configmap.yaml

yaml

apiVersion: v1
kind: Service
metadata:
  namespace: ruoyi
  name: mysql
  labels:
    app: mysql-service
spec:
  selector:
    app: mysql-pod

    - nodePort: 30006
      port: 3306
      protocol: TCP
      targetPort: 3306

          - name: data
            mountPath: /var/lib/mysql
          - name: logs
            mountPath: /var/log/mysql/
          - name: config
            mountPath: /etc/mysql/conf.d
      volumes:
        - name: init
          nfs:
            server: 192.168.10.113
            path: /nfs/data/mysql/init
        - name: data
          nfs:
            server: 192.168.10.113
            path: /nfs/data/mysql/data
        - name: logs
          nfs:
            server: 192.168.10.113
            path: /nfs/data/mysql/logs
        - name: config
          configMap:
            name: mysql-configmap

---

  my.cnf: |
    [mysqld]
    datadir=/var/lib/mysql

    symbolic-links=0
    [mysqld_safe]
    log-error=/var/log/mysql/mysql.log
    pid-file=/var/run/mysql/mariadb.pid

应用资源

shell

kubectl apply -f mysql-svc-deploy-configmap.yaml

查看 mysql 容器状态

shell

kubectl exec -it -n ruoyi mysql-859c4c69b-xfrj7 -- /bin/bash

部署redis

在nfs共享目录下创建data和config，分别挂载redis的数据和配置
shell
```
mkdir -p /nfs/data/redis/data
mkdir -p /nfs/data/redis/config
```
将配置文件redis.conf放到config目录下，注意修改其中的dir属性配置为data的mountPath
```
# requirepass 123456
dir /data
```

创建资源文件redis-svc-deploy.yaml

yaml

apiVersion: v1
kind: Service
metadata:
  namespace: ruoyi
  name: redis
  labels:
    app: redis-service
spec:
  selector:
    app: redis-pod
  type: NodePort
  ports:
    - nodePort: 30379
      port: 6379
      protocol: TCP
      targetPort: 6379

        command:
          - redis-server
        args:
          - /etc/redis/redis.conf
        env:
          - name: TZ
            value: Asia/Shanghai
        volumeMounts:
          - name: data
            mountPath: /var/lib/redis
          - name: config
            mountPath: /etc/redis/
      volumes:
        - name: data
          nfs:
            server: 192.168.10.113
            path: /nfs/data/redis/data
        - name: config
          nfs:
            server: 192.168.10.113
            path: /nfs/data/redis/config

应用资源
shell
```
kubectl apply -f redis-svc-deploy.yaml
```

部署ry-admin

在nfs共享目录下创建ry-admin，挂载ruoyi-admin的日志以及头像等文件

注意替换spring配置文件中有关ip地址的配置，替换为service的name，如下：

yaml

spring:
  datasource:
    druid:
      master:
        url: jdbc:mysql://mysql:3306/ry-vue
  redis:
    host: redis

镜像制作

bash

mvn clean package
docker build -t ry-admin:3.8.5 .

Dockerfile

FROM openjdk:8-jre
MAINTAINER lxw@qq.com
VOLUME /tmp
ADD ruoyi-admin.jar app.jar
ENV TZ 'Asia/Shanghai'
ENV LANG C.UTF-8
ENV LANGUAGE C.UTF-8
ENV LC_ALL C.UTF-8
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]

创建资源文件ry-admin-svc-deploy.yaml

yaml

apiVersion: v1
kind: Service
metadata:
  namespace: ruoyi
  name: ry-admin
  labels:
    app: ry-admin-service
spec:
  selector:
    app: ry-admin-pod
  type: NodePort
  ports:
    - nodePort: 30080
      port: 8080
      protocol: TCP
      targetPort: 8080

---
apiVersion: apps/v1
kind: Deployment
metadata:
  namespace: ruoyi
  name: ry-admin
  labels:
    app: ry-admin-deploy
spec:
  selector:
    matchLabels:
      app: ry-admin-pod
  replicas: 1
  template:
    metadata:
      labels:
        app: ry-admin-pod
    spec:
      containers:
      - name: ry-admin
        image: registry.cn-shanghai.aliyuncs.com/cr-k8s-images/ry-admin:3.8.5
        ports:
          - containerPort: 8080
        env:
          - name: TZ
            value: Asia/Shanghai
        volumeMounts:
          - name: data
            mountPath: /home/ruoyi
      volumes:
        - name: data
          nfs:
            server: 192.168.10.113
            path: /nfs/data/ry-admin

应用资源

shell

kubectl apply -f ry-admin-svc-deploy.yaml

这里打包 ry-admin 镜像有大坑（有墙，本地无法打docker镜像）
利用远程云服务器打包
打包完推送阿里云私有镜像库
在k8s机器上手动拉取阿里云私有镜像
docker pull registry.cn-shanghai.aliyuncs.com/cr-k8s-images/ry-admin:3.8.5

shell

sudo docker login --username=theWe1 registry.cn-shanghai.aliyuncs.com

docker tag 13ffe4493175 registry.cn-shanghai.aliyuncs.com/cr-k8s-images/ry-admin:3.8.5

docker push registry.cn-shanghai.aliyuncs.com/cr-k8s-images/ry-admin:3.8.5

部署ry-ui

在nfs共享目录下创建ry-ui以及子目录dist和config，挂载ruoyi-ui的静态文件以及nginx的配置

将配置文件nginx.conf放到config目录下（这里踩过坑最后方案是挂载的 conf.d 目录）

ry-ui-custom.conf

server {
	listen       80;
	server_name  localhost;
	charset utf-8;

	location / {
		root   /home/ruoyi/projects/ruoyi-ui;
		try_files $uri $uri/ /index.html;
		index  index.html index.htm;
	}
	
	location /prod-api/ {
		proxy_set_header Host $http_host;
		proxy_set_header X-Real-IP $remote_addr;
		proxy_set_header REMOTE-HOST $remote_addr;
		proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
		proxy_pass http://ry-admin:8080/;
	}

	error_page   500 502 503 504  /50x.html;
	location = /50x.html {
		root   html;
	}
}

静态文件打包，将静态文件放到dist目录下
```
npm run build:prod
```

创建资源文件ry-ui-svc-deploy.yaml

yaml

apiVersion: v1
kind: Service
metadata:
  namespace: ruoyi
  name: ry-ui
  labels:
    app: ry-ui-service
spec:
  selector:
    app: ry-ui-pod
  type: NodePort
  ports:
    - nodePort: 30081
      port: 80
      protocol: TCP
      targetPort: 80

---
apiVersion: apps/v1
kind: Deployment
metadata:
  namespace: ruoyi
  name: ry-ui
  labels:
    app: ry-ui-deploy
spec:
  selector:
    matchLabels:
      app: ry-ui-pod
  replicas: 1
  template:
    metadata:
      labels:
        app: ry-ui-pod
    spec:
      containers:
      - name: nginx
        image: registry.cn-shanghai.aliyuncs.com/cr-k8s-images/nginx:1.22.1
        ports:
          - containerPort: 80
        volumeMounts:
          - name: dist
            mountPath: /home/ruoyi/projects/ruoyi-ui
          - name: config
            mountPath: /etc/nginx/conf.d
      volumes:
        - name: dist
          nfs:
            server: 192.168.10.113
            path: /nfs/data/ry-ui/dist
        - name: config
          nfs:
            server: 192.168.10.113
            path: /nfs/data/ry-ui/config

系统测试

若是k8s集群部署 ruoyi成功，通过任意节点的30081端口应该都能够访问到 ruoyi-admin
