:writing\_hand: This video is an introduction to <mark style="background-color:blue;">docker-compose</mark> where we will learn how to configure postgres and pgadmin in a <mark style="background-color:blue;">docker-compose</mark> yaml file. We will then learn how to run and close it down.

{% hint style="info" %} <mark style="background-color:blue;">docker-compose</mark> comes with docker desktop on Mac & Windows. You can read more about docker compose here <https://docs.docker.com/compose/>
{% endhint %}

"Compose simplifies the control of your entire application stack, making it easy to manage services, networks, and volumes in a single, comprehensible YAML configuration file. Then, with a single command, you create and start all the services from your configuration file." - <https://docs.docker.com/compose/>. Now, we do not need to do the network steps we did in 1.2.3 to connect our two containers under a network, but instead can use a docker-compose YAML file.

:pencil: docker-compose.yaml

```yaml
services:
  pgdatabase:
    image: postgres:13
    environment:
      - POSTGRES_USER=root
      - POSTGRES_PASSWORD=root
      - POSTGRES_DB=ny_taxi
    volumes:
      - "./ny_taxi_postgres_data:/var/lib/postgresql/data:rw"
    ports:
      - "5432:5432"
  pgadmin:
    image: dpage/pgadmin4
    environment:
      - PGADMIN_DEFAULT_EMAIL=admin@admin.com
      - PGADMIN_DEFAULT_PASSWORD=root
    ports:
      - "8080:80"
```

:black\_medium\_square: Terminal runs the docker-compose.yaml  and `-d` so we can still use our terminal

```bash
docker-compose up -d
```

:black\_medium\_square: Terminal stops the run

```bash
docker-compose down
```

:eyes: Note that in the current docker compose, we now write `compose.yaml` files and run it using `docker compose up -d` so there is a space between the works instead of a dash -.
