Docker Compose File

A Docker Compose.yml is a file containing information about your Docker image.

In short, Docker Compose works by applying many rules declared within a single docker-compose.yml configuration file. These YAML rules, both human-readable and machine-optimized, provide an effective way to snapshot the whole project from ten-thousand feet in a few lines. Almost every rule replaces a specific Docker command, so that in the end, we just need to run: docker-compose up.

If you are using Portainer, the equivalent of a docker-compose.yml would be a Portainer Stack.

Windows

I find it funny how things like Docker and the docker-compose.yml used to feel like a scary or difficult thing when I was on Microsoft Windows, but now that I am using Ubuntu it has become the most normal every day thing.
