我试图对我的 nodejs-mysql 应用程序进行 dockerize。我有两个容器 Nodejs 和 Mysql。 Mysql 容器有一个到 3306 的开放端口。
这是我的 Dockerfile：
FROM 节点：最新
工作目录 /app
复制包*.json ./
运行 npm install -g nodemon
运行 npm install
复制。 .
这是我的 docker-compose.yml 文件：
version: "3.8"
services:
express-server:
build:
context: .
environment:
MYSQL_HOST: mysql-service
MYSQL_USER: 'root'
MYSQL_ROOT_PASSWORD: 'root'
MYSQL_DATABASE: 'warehouse'
entrypoint: ["npm", "start"]
ports:
- "8080:8000"
volumes:
- .:/app
- /app/node_modules
depends_on:
- mysql-service
mysql-service:
image: mysql
environment:
MYSQL_ROOT_PASSWORD: 'root'
MYSQL_DATABASE: 'warehouse'
ports:
- "3306:3306"
volumes:
- mysql-db-data:/var/lib/mysql
- mysql-db-config-data:/etc/mysql
volumes:

出现的错误：
