Connect to PostgreSQL Database in Docker Container from DBeaver - ruby-on-rails

Question

I can't get the connection between my PostgreSQL database from my Rails app which is running in a Docker container working.
The application just works fine, I just can't connect to the database.
docker-compose.yml:
services:
app:
build:
context: .
dockerfile: app.Dockerfile
container_name: application_instance
command: bash -c "bundle exec puma -C config/puma.rb"
volumes:
- .:/app
- node-modules:/app/node_modules
- public:/app/public
depends_on:
- database
- redis
env_file:
- .env
database:
image: postgres
container_name: database_instance
restart: always
volumes:
- db_data:/var/lib/postgresql/data
ports:
- "5432:5432"
env_file:
- .env
environment:
POSTGRES_USER: ${POSTGRES_USER}
POSTGRES_PASSWORD: ${POSTGRES_PASSWORD}
POSTGRES_DB: ${POSTGRES_PRODUCTION_DB}
nginx:
build:
context: .
dockerfile: nginx.Dockerfile
depends_on:
- app
volumes:
- public:/app/public
ports:
- "80:80"
redis:
image: redis
container_name: redis_instance
ports:
- "6379:6379"
sidekiq:
container_name: sidekiq_instance
build:
context: .
dockerfile: app.Dockerfile
depends_on:
- redis
- database
command: bundle exec sidekiq
volumes:
- .:/app
env_file:
- .env
volumes:
db_data:
node-modules:
public:
If I try to connect via DBeaver I get the following message:
Any idea what's going wrong here? The port should be exposed on my local machine. I also tried with the IP of the container, but then I get a timeout exception.

Answer 1

This is because you most likely have postgres running locally on your machine (port 5432) and also on a docker (port 5432). Dbeaver wants to connect to database on your local machine, than on docker.
Any solution I figure out is to temporary stop/turn of your local postgres service (on Windows: Task manager -> Services -> (postgres service) -> stop).
I was also struggling with issue.
