docker-compose configs

Docker Compose configs are used to define and configure multi-container Docker applications. With Docker Compose, you can specify the services, networks, volumes, and other configurations required for your application in a single YAML file called `docker-compose.yml`.

In the `docker-compose.yml` file, you can define multiple services, each representing a container in your application. Each service can have its own configuration, such as the image to use, environment variables, ports to expose, volumes to mount, etc.

Here's an example of a simple `docker-compose.yml` file:

version: '3'
services:
  web:
    image: nginx:latest
    ports:
      - 80:80
    volumes:
      - ./html:/usr/share/nginx/html
  db:
    image: mysql:latest
    environment:
      - MYSQL_ROOT_PASSWORD=secret
      - MYSQL_DATABASE=mydb
      - MYSQL_USER=myuser
      - MYSQL_PASSWORD=mypassword

In this example, two services are defined: `web` and `db`. The `web` service uses the `nginx` image, exposes port 80 on the host, and mounts a local directory `./html` to the container's `/usr/share/nginx/html` directory. The `db` service uses the `mysql` image and sets some environment variables for configuration.

You can use the `docker-compose` command-line tool to manage and interact with your Docker Compose application. For example, you can start the application using `docker-compose up`, stop it using `docker-compose down`, or view logs using `docker-compose logs`.

I hope this helps! Let me know if you have any more questions.
