## PostgreSQL and pgAdmin
This example provides a base setup for using [PostgreSQL](https://www.postgresql.org/) and [pgAdmin](https://www.pgadmin.org/).
More details on how to customize the installation and the compose file can be found [here (PostgreSQL)](https://hub.docker.com/_/postgres) and [here (pgAdmin)](https://www.pgadmin.org/docs/pgadmin4/latest/container_deployment.html).
Project structure:
```
.
├── .env
├── compose.yaml
└── README.md
```
[_compose.yaml_](compose.yaml)
``` yaml
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](.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).
``` shell
$ 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.
1. Right-click "Servers" in the top-left corner and select "Create" -> "Server..."
2. Name your connection
3. 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
d3cde3b455ee dpage/pgadmin4:latest "/entrypoint.sh" 9 minutes ago Up 9 minutes 443/tcp, 0.0.0.0:5050->80/tcp, :::5050->80/tcp pgadmin
```
Stop the containers with
``` shell
$ docker compose down
# To delete all data run:
$ docker compose down -v
```
