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.
