我正在使用 typescript、express 和 Sequelize
构建 api 服务器.
这是我的 database
连接类。
export class Database {
private _sequelize: Sequelize;
private config: DBConfigGroup = dbConfig;
private env = process.env.NODE_ENV as string;
constructor() {
this._sequelize = new Sequelize({
dialect: 'postgres',
database: this.config[this.env].database,
username: this.config[this.env].username,
password: this.config[this.env].password,
host: this.config[this.env].host,
});
}
async connect(): Promise<void> {
try {
console.log('start connect');
await this._sequelize.authenticate();
console.log('Connection has been established successfully.'.green.bold);
} catch (error) {
console.error('Unable to connect to the database:'.red.bold, error);
}
}
async close(): Promise<void> {
try {
await this._sequelize.close();
console.log('Connection has been close successfully.'.red.bold);
} catch (error) {
console.error('Unable to close to the database:'.yellow.bold, error);
}
}
get sequelize(): Sequelize {
return this._sequelize;
}
}
所以在我的
server.ts
,我在叫这个dotenv.config({
path: './config/environments/config.env',
});
const database = new Database();
console.log('Init db');
database
.connect()
.then(() => {
console.log('success db ininit');
})
.catch((err) => {
console.log('fail db init: ', err);
});
/**
* Server Activation
*/
const server = app.listen(PORT, () => {
console.log(`Server running in ${process.env.NODE_ENV} mode on port ${PORT}`.yellow.bold);
});
所以在我的本地开发中一切正常
但是当我尝试使用
docker compose
运行它时有了这个配置// docker-compose.yml
version: '3.4'
services:
api:
stdin_open: true
tty: true
build:
context: ./api
dockerfile: Dockerfile.dev
ports:
- "5000:5000"
volumes:
- /app/node_modules
- ./api:/app
这是我的
Dockerfile.dev
文件FROM node:alpine
ENV NODE_ENV=development
WORKDIR /app
EXPOSE 5000
COPY package.json package-lock.json* ./
RUN npm install && npm cache clean --force
COPY . .
CMD ["npm", "run", "dev:docker"]
但问题是当我运行
docker-compose up --build
我只看到这些日志
api_1 | Init db
api_1 | start connect
api_1 | Server running in development mode on port 5000
所以基本上没有回应是否
sequelize.authenticate()
是成功还是失败,只是
Server running in development mode on port 5000
注销,毕竟什么都没有。为什么它不能像在本地那样在 docker 内部工作,我错过了任何配置?
谢谢
最佳答案
你可以试试 node:10 版本
我有同样的问题,但是当将图像更改为 node:10 时,该问题就消失了
希望能帮到你
关于node.js - Sequelize.authenticate() 对 Docker 内部的 google cloud sql 连接不起作用(没有成功或错误响应),我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/61663848/
