Plug Postgres database on Navicat using prisma

Question

Im currently doing an app using Prisma and a Postgres database and I can't connect my database to Navicat. I'm a beginner with docker and dont understand completely how services work. My current docker-compose.yml is

version: '3'
services:
  prisma:
    image: prismagraphql/prisma:1.8
    restart: always
    ports:
    - "4466:4466"
    environment:
      PRISMA_CONFIG: |
        port: 4466
        # uncomment the next line and provide the env var PRISMA_MANAGEMENT_API_SECRET=my-secret to activate cluster security
        # managementApiSecret: my-secret
        databases:
          default:
            connector: postgres
            host: postgres
            port: 5432
            user: prisma
            password: prisma
            migrations: true
  postgres:
    image: postgres
    restart: always
    environment:
      POSTGRES_USER: prisma
      POSTGRES_PASSWORD: prisma
    volumes:
      - postgres:/var/lib/postgresql/data
volumes:
  postgres:

And what I tried on Navicat is this, what seems to me correct but it would appear that no.

Thank you for you help !

You need to use port mapping using the ports property for your postgres container:

version: '3'
services:
  prisma:
    image: prismagraphql/prisma:1.8
    restart: always
    ports:
    - "4466:4466"
    environment:
      PRISMA_CONFIG: |
        port: 4466
        # uncomment the next line and provide the env var PRISMA_MANAGEMENT_API_SECRET=my-secret to activate cluster security
        # managementApiSecret: my-secret
        databases:
          default:
            connector: postgres
            host: postgres
            port: 5432
            user: prisma
            password: prisma
            migrations: true
  postgres:
    image: postgres
    restart: always
    ports:
    - "5432:5432"
    environment:
      POSTGRES_USER: prisma
      POSTGRES_PASSWORD: prisma
    volumes:
      - postgres:/var/lib/postgresql/data
volumes:
  postgres:

Then you should be able to connect to localhost:5432 with a Postgres client, like Navicat.
