Docker docker compose postgresql error

Time：10-04

I have an error connecting postgresql and app with docker compose. It seems to me that the problem lies in the fact that I connected the database via localhost(https://i.stack.imgur.com/PuthE.png). I tried to create a container based on the postgresql image, but intellij IDEA did not see the databases that I created in the container.

**The failed attempt I'm talking about **

docker run -d -port 5432:5432 --name psql-img -e POSTGRES_PASSWORD=admin postgres:13
docker exec -it psql-img bash

than I connected to the empty database that I create in psql-img container

psql -h db -p5432 -U postgres -W glerondb

CodePudding user response：

Regarding postgresql, use environment variables POSTGRES_ instead of POSTGRESQL_.

Furthermore, you can add container_name to force a name for your service container.

Otherwise it would be <directory>_<service name>_<index>

version: "3.7"

services:
  gleron:
    image: igleron
    container_name: cgleron
    build: ./
    environment:
      SPRING_DATASOURCE_URL: jdbc:postgresql://db:5432/gleron
    depends_on:
      - db
    ports:
      - "8080:8080":
  db:
    container_name: db
    image: postgres
    environment:
      POSTGRES_PASSWORD: admin
      POSTGRES_USER: postgres
      POSTGRES_DB: gleron
    volumes:
    - ./pgdata:/var/lib/postgresql/data
    ports:
    - "5432:5432"

You can check docker-compose container states with docker-compose ps
