Add a postgres server to pgadmin4, through bash commands in a docker compose file

I’m trying to add a postgres server to pgadmin4, through bash commands in a docker compose file.
Here’s my docker compose file:

version: '3.9'
services:
  podcast_db:
    image: postgres:15.3-alpine
    container_name: podcast_db
    ports:
      - 5432:5432
    volumes:
      - podcast_db_data:/usr/share/podcast_db/data
    env_file:
      - ./database/.env.local.db
    # instead, we could have created a `environment` section, with
    # with the env vars in .env.local.db file.
  podcast_pgadmin:
    image: dpage/pgadmin4
    container_name: pgadmin4_container
    ports:
      - 5050:80
    env_file:
      - ./database/.env.local.db
    command: >
      sh -c " sudo apt-get install jq
      | TOKEN=$(curl -s -X POST -d "username=${PGADMIN_DEFAULT_EMAIL}&password=${PGADMIN_DEFAULT_PASSWORD}" ${PGADMIN_URL}/api/v1/auth/login | jq -r .access_token)
      | curl -X POST -H "Authorization: Bearer ${TOKEN}" -H "Content-Type: application/json" -d '{
        "name": "'${POSTGRES_NAME}'",
        "host": "'${POSTGRES_HOST}'",
        "port": '${POSTGRES_PORT}',
        "ssl_mode": "prefer",
        "maintenance_database": "'${POSTGRES_DB}'",
        "username": "'${POSTGRES_USER}'",
        "password": "'${POSTGRES_PASSWORD}'"
      }' ${PGADMIN_URL}/api/v1/servers"


volumes:
  podcast_db_data:

The part above, in the command section, was done with the help of chatGPT… yeah. 😀

I can add the server, using the pgadmin GUI, without any problem…

However, I want to add it from bash.

When I do docker compose up, I don’t get any error messages in the terminal, and when I check through the GUI, no server has been added…

Here is the log of the pgadming container:

NOTE: Configuring authentication for SERVER mode.

All help would be appreciated.

    You could easily do that by mapping a servers.json(/pgadmin4/servers.json) file. Checkout https://www.pgadmin.org/docs/pgadmin4/7.7/container_deployment.html#examples

    Then servers.json file will be automatically imported on start.

    This is a detailed solution step by step. I have spent a little bit of time to solve it, I followed this post from the early days, but I have a problem with the port, I configed wrong port. Now I test sucessfully.

    current folder:

    • postgres_data
    • docker-compose.yaml
    • pgpass
    • servers.json
    1. servers.json:
      with name is hostname in pgdatabase service
    {
  "Servers": {
    "1": {
      "Name": "pgdatabase",
      "Group": "Servers",
      "Host": "host.docker.internal",
      "Port": 5431,
      "MaintenanceDB": "postgres",
      "Username": "root",
      "PassFile": "/pgpass",
      "SSLMode": "prefer"
    }
  }
}
    1. pgpass: 
    host.docker.internal:5431:postgres:root:root
    1. docker-compose.yaml
    services:
  pgdatabase:
    image: postgres:13
    hostname: pgdatabase
    environment:
      - POSTGRES_USER=root
      - POSTGRES_PASSWORD=root
      - POSTGRES_DB=postgres
    volumes:
      - postgres_data:/var/lib/postgresql/data:rw
    ports:
      - "5431:5432"
    networks:
      - pg-network-week4

  pgadmin:
    restart: always
    image: dpage/pgadmin4
    environment:
      - [email protected]
      - PGADMIN_DEFAULT_PASSWORD=root
    ports:
      - "8080:80"
    networks:
      - pg-network-week4
    volumes:
      - ./servers.json:/pgadmin4/servers.json
      - ./pgpass:/pgpass
    depends_on:
      - pgdatabase
networks:
  pg-network-week4:
    name: pg-network-week4
volumes:
  postgres_data:
