MCP应用k8s部署

一、概述

生产环境dify是部署在k8s里面的，MCP应用虽然在ECS的docker中运行，没法做到统一管理，所以需要部署在k8s里面才行。

二、部署

推送镜像

上一篇文章，已经制作好了docker镜像，链接：https://www.cnblogs.com/xiao987334176/p/18827297

这里就需要把镜像推送到harbor私有仓库

docker tag mysql_mcp_server_pro:v1 harbor.qq.com:8083/mcp/mysql_mcp_server_pro:v1
docker push harbor.qq.com:8083/mcp/mysql_mcp_server_pro:v1

命名空间

创建命名空间mcp

kubectl create namespace mcp

创建拉取镜像需要的密钥

kubectl create secret docker-registry harbor-key --docker-server=harbor.qq.com:8083 --docker-username=devops --docker-password=1sB5r9UShgK5 --namespace=mcp

编写yaml文件

Deployment.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  namespace: mcp
  name: mysql-mcp-server-pro
  labels:
    app: mysql-mcp-server-pro
spec:
  selector:
    matchLabels:
      app: mysql-mcp-server-pro
  replicas: 1
  template:
    metadata:
      labels:
        app: mysql-mcp-server-pro
    spec:
      imagePullSecrets:
        - name: harbor-key
      containers:
        - name: mysql-mcp-server-pro
          image: "harbor.qq.com/mcp/mysql_mcp_server_pro:v1"
          imagePullPolicy: Always
          env:
            - name: MYSQL_HOST
              value: '192.168.20.128'
            - name: MYSQL_PORT
              value: '3306'
            - name: MYSQL_USER
              value: 'root'
            - name: MYSQL_PASSWORD
              value: 'abcd@1234'
            - name: MYSQL_DATABASE
              value: 'test'
          resources:
            limits:
              cpu: 0.1
              memory: 300Mi
            requests:
              cpu: 0.1
              memory: 100Mi
          ports:
            - containerPort: 9000

Service.yaml

apiVersion: v1
kind: Service
metadata:
  namespace: mcp
  name: mysql-mcp-server-pro-svc
  labels:
    app: mysql-mcp-server-pro-svc
spec:
  ports:
    - port: 9000
      name: mysql-mcp-server-pro-svc
  selector:
    app: mysql-mcp-server-pro

发布应用

kubectl apply -f Deployment.yaml
kubectl apply -f Service.yaml

三、dify测试

登录dify，编辑插件MCP SSE

 修改配置

 修改为k8s svc地址

{
    "mysql-mcp-server-pro": {
        "url": "http://mysql-mcp-server-pro-svc.mcp:9000/sse",
        "headers": {},
        "timeout": 60,
        "sse_read_timeout": 300
    }
}

进入dify工作流，修改mcp地址
