TypeORM migration:run not working errno: -3008,getaddrinfo ENOTFOUND

Question

Do you know why I get the following error when I try to run typeorm:run to execute migration?

node --require ts-node/register ./node_modules/typeorm/cli.js migration:run
Error during migration run:
Error: getaddrinfo ENOTFOUND users-service-db
at GetAddrInfoReqWrap.onlookup [as oncomplete] (node:dns:69:26) {
errno: -3008,
code: 'ENOTFOUND',
syscall: 'getaddrinfo',
hostname: 'users-service-db',
fatal: true
 }
error Command failed with exit code 1.

my config is

users-service-db:
   environment:
     - MYSQL_ROOT_PASSWORD=password
     - MYSQL_DATABASE=db
   image: mysql:5.7.20
   ports:
     - "7201:3306"

the users-service-db is running does this Error: getaddrinfo ENOTFOUND users-service-db say that the host doesn't know what to do. Can you help?

After trying Answer 1 and 2 still getting the same error don't know what to do it worked before?

version: "3"
services:
  api-gateway:
    build:
      context: "."
      dockerfile: "./api-gateway/Dockerfile"
    depends_on:

      - users-service
    ports:

    volumes:
      - ./api-gateway:/opt/app

  chat-service:
    build:

    depends_on:
      - chat-service-db
    ports:
      - "7100:7100"
    volumes:
      - ./chat-service:/opt/app

    ports:

    volumes:

  users-service:
    build:
      context: "."
      dockerfile: "./users-service/Dockerfile"
    depends_on:
      - users-service-db
    ports:
      - "7101:7101"
    volumes:
      - ./users-service:/opt/app

  users-service-db:
    environment:
      - MYSQL_ROOT_PASSWORD=password
      - MYSQL_DATABASE=db
    image: mysql:5.7.20
    ports:
      - "7201:3306"
    hostname: 'localhost'

finally I resolved the error thanks to @Eranga Heshan

I created an additional ormConfig.js file at pasted this:

export = {
  "type": "mysql",
  "host": "localhost",
  "port": 7201,
  "username": "root",
  "password": "password",
  "database": "db",
  "synchronize": true,
  "logging": false,
  "entities": [
  "src/entities/**/*.ts"
  ],
  "migrations": [
  "./src/db/migrations/**/*.ts"
  ],
  "cli": {
  "entitiesDir": "src/db/entities",
  "migrationsDir": "src/db/migrations"
  }
 }

then

node --require ts-node/register ./node_modules/typeorm/cli.js migration:run --config src/db/migrations/ormConfig

Answer 1

Your VS Code terminal is running inside your machine. So it can't resolve users-service-db host.

You can do this in two ways.

1. Using a new config file and execute migrations from your localhost

• Create a new typeorm connection config file migrationsOrmConfig.ts and put it inside your project (Let's say you put it in src/migrations directory)

  export = {
    host: 'localhost',
    port: '7201',
    type: 'mysql',
    user : 'root',
    password : 'password',
    database : 'db' ,
  };
  

• Now you can modify the command you used earlier to run migrations

  node --require ts-node/register ./node_modules/typeorm/cli.js migration:run --config src/migrations/migrationsOrmConfig
  

2. Execute migrations from a terminal within the container

• In your VSCode terminal type

  docker ps -a
  

• Get the CONTAINER ID of user-service (Let's say it is CONTAINER_ID)

• Open up a terminal inside the container

  docker exec -it CONTAINER_ID /bin/bash
  

• Execute the command you used earlier to run migrations (if the following command complained about typeorm node module not being found, you can install it inside the container)

  node --require ts-node/register ./node_modules/typeorm/cli.js migration:run
