I have 2 docker composes , one is Infrastructures and the second is Appplications.
I need a direct line from Appplications => Infrastructures , to run migrations on a Postresql container in
Appplications docker ,and it (Infrastructures) must be listening before make requests from
version: "3" networks: shared_network: driver: bridge services: # PostgreSQL my_postgres: image: postgres:latest environment: .... // ENVS ports: - "5432:5432" healthcheck: test: ["CMD", "curl", "-f", "http://localhost:5432"] interval: 30s timeout: 10s retries: 15 networks: - shared_network ... more infrastructures
version: "3" networks: shared_network: driver: bridge services: # Employees Service emps: build: context: ./emps_service dockerfile: ./Dockerfile ports: - "9000:9000" networks: - shared_network ... More apps
I’m using default.yaml for Sequelize :
... more definitions sequelize: database: some_random_db host: my_postgres user: xxxx password: yyyy dialect: postgres seederStorage: "sequelize"
and when I run
docker-compose up , twice , first for the Infrastructures , and only once it’s up another
docker-compose up for the Applications , I get :
**SequelizeHostNotFoundError: getaddrinfo ENOTFOUND my_postgres**
How can we fix this ?
