DB_PORT=3306

DB_USERNAME=root
DB_PASSWORD=secret
I tried to set DB_HOST as localhost and mysql(as it is in Docker), but nothing solved my problem. Mysql server is running in docker, and when I do migrations in database it works, but when I try to register user, I am getting
SQLSTATE[HY000] [2002] Connection refused
SELECT count(*) AS aggregate FROM `users` WHERE `email` = test#gmail.com
What else should I do? I cleared cache and config cache. I have no idea what to do else.

I solved it by php artisan swoole:http start and I registered through that link http://127.0.0.1:1215

Error database connect is not a function Nodejs with Mysql in docker

I have deployed my docker application (to DigitalOcean). Everything work's, but I can't connect mysql with nodejs.
When I run docker-compose up I get error database.connect is not a function.
My server.js file is look like this
const mysql = require("mysql");
const database = mysql.createPool({
host: process.env.MYSQL_HOST_IP,
user: "db_user",
password: "db_user_pass",
database: "guess-game",
port: 3306,
});
database.connect((err) => {
if (err) {
console.error("error connecting: " + err.stack);
return;
}
console.log("connected as id " + db.threadId);
});
module.exports = db;
I don't know what I need to write this line to make it work.
host: process.env.MYSQL_HOST_IP,
I tried to add droplet IP as host, but this is also don't work.
host: "http://46.101.162.111/",
Also, I try this.

Struggling almost 3 days. 😣

You just need to indicate a DB container name instead of IP like this:
MYSQL_HOST_IP=db

When I run docker-compose up the MySQL container successfully launches. But the app exits, with error code Error: connect ETIMEDOUT.
When I run the app locally via node app.js I end up getting a successful "Connected!" message output to my console.
I'm able to connect to the database via MySQLWorkbench as well. It's just the app is unable to connect to the db when the app is ran as a container.

You've specified that the app should be on a named network and the database shouldn't. Then the database service goes on the default network and the two containers can't talk to each other.
I'd remove the named network from the app, since it's probably not needed.

Docker Compose getting error ECONNREFUSED 127.0.0.1:3306 with MySQL and NodeJS

I am trying to setup some containers for my NestJS + TypeORM + MySQL environment by using Docker Compose in a Windows 10 host, but I am getting an ECONNREFUSED error:
connect ECONNREFUSED 127.0.0.1:3306 +2ms

I have created the following Dockerfile to configure the NestJS API container:
FROM node:12-alpine
WORKDIR /usr/src/app
COPY package.json .
RUN npm install
EXPOSE 3000
#CMD ["npm", "start"]
CMD /wait-for-it.sh db:3306 -- npm start
COPY . .
And then I reference this from Docker Compose with the following docker-compose.yml:
version: "3.8"
networks:
app-tier:
driver: bridge
services:
db:
image: mysql
command: --default-authentication-plugin=mysql_native_password
restart: always
expose:
- "3306"
ports:
- "3306:3306"
networks:
- app-tier
environment:
MYSQL_DATABASE: school
MYSQL_ALLOW_EMPTY_PASSWORD: ok
MYSQL_ROOT_PASSWORD: root
MYSQL_USER: dbuser
MYSQL_PASSWORD: dbuser
MYSQL_ROOT_HOST: '%'
backend:
depends_on:
- db
build: .
ports:
- "3000:3000"
networks:
- app-tier
Finally, I set the TypeORM configuration to match with the Docker Compose file:
export const DB_CONFIG: TypeOrmModuleOptions = {
type: 'mysql',
host: 'db',
port: 3306,
username: 'dbuser',
password: 'dbuser',
database: 'school',
entities: [], // We specify the entities in the App Module.
synchronize: true,
};
I am kind of new to Docker Compose, but I have tried many things like changing the output port to 3307, setting an explicit network... and the port 3306 is free in my host OS when I run it. Any help?
Edit 1
I have included MYSQL_ROOT_HOST and wait-for-it.sh as suggested, but still no results.

I think your db is taking more time to start and your app is starting before the db, try something like this for your docker-compose.yml file:
version: "3.8"
networks:
app-tier:
driver: bridge
services:
db:
image: mysql
command: --default-authentication-plugin=mysql_native_password
restart: always
expose:
- "3306"
ports:
- "3306:3306"
networks:
- app-tier
environment:
MYSQL_DATABASE: school
MYSQL_ALLOW_EMPTY_PASSWORD: ok
MYSQL_ROOT_PASSWORD: root
MYSQL_USER: dbuser
MYSQL_PASSWORD: dbuser
MYSQL_ROOT_HOST: '%'
backend:
depends_on:
- db
build: .
command: bash -c 'while !</dev/tcp/db/3306; do sleep 1; done; npm start'
ports:
- "3000:3000"
networks:
- app-tier
