PostgreSQL and pgAdmin
This example provides a base setup for using PostgreSQL and pgAdmin. More details on how to customize the installation and the compose file can be found here (PostgreSQL) and here (pgAdmin).
Project structure:
.
├── .env
├── docker-compose.yaml
└── README.md
services:
postgres:
image: postgres:latest
...
pgadmin:
image: dpage/pgadmin4:latest
Configuration
.env
Before deploying this setup, you need to configure the following values in the .env file.
- POSTGRES_USER
- POSTGRES_PW
- POSTGRES_DB (can be default value)
- PGADMIN_MAIL
- PGADMIN_PW
Deploy with docker-compose
When deploying this setup, the pgAdmin web interface will be available at port 5050 (e.g. http://localhost:5050).
$ docker-compose up
Starting postgres ... done
Starting pgadmin ... done
Add postgres database to pgAdmin
After logging in with your credentials of the .env file, you can add your database to pgAdmin.
- Right-click "Servers" in the top-left corner and select "Create" -> "Server..."
- Name your connection
- Change to the "Connection" tab and add the connection details:
- Hostname: "postgres" (this would normally be your IP address of the postgres database - however, docker can resolve this container ip by its name)
- Port: "5432"
- Maintenance Database: $POSTGRES_DB (see .env)
- Username: $POSTGRES_USER (see .env)
- Password: $POSTGRES_PW (see .env)
Expected result
Check containers are running:
$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
849c5f48f784 postgres:latest "docker-entrypoint.s…" 9 minutes ago Up 9 minutes 0.0.0.0:5432->5432/tcp, :::5432->5432/tcp postgres

Stop the containers with
$ docker-compose down
# To delete all data run:
$ docker-compose down -v
