How do I set up a multi-container application using Docker Compose?
To set up a multi-container application with Docker Compose, you need to create a docker-compose.yml
file that defines your services.
What should I include in the docker-compose.yml
file?
You should define each service, specify the image to use, and configure any necessary ports, volumes, and environment variables.
Can you give me an example of a docker-compose.yml
file?
Sure! Here's a simple example:
version: '3'
services:
web:
image: nginx
ports:
- "80:80"
db:
image: postgres
environment:
POSTGRES_PASSWORD: example
