我正在用typescript,express和 Sequelize
.
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,在我的本地发展中,一切都很好。
但当我尝试用 docker compose
以此配置
// 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
档案
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
注销后,什么都没有。
为什么在docker里面不能像在本地一样工作,我漏掉了什么配置?
谅谅
你可以试试node:10的版本,我也有同样的问题,但是当把图片改成node:10的时候,这个问题就没有了希望能帮到你。
