How to run docker compose YML file

Question

How can I open a YML compose file on my computer? I've installed Docker for Windows and Docker tools but couldn't figure out how to do it.

Answer 1

You can run the following command to run the docker-compose.yaml file:

docker-compose -f {compose file name} up

You can ignore the -f flag if your file name is docker-compose.yaml

Answer 2

To run and open .yml files you have to install Docker Compose.

After the installation, go to your docker-compose.yml directory and then execute docker-compose up to create and start services in your docker-compose.yml file.

This only works if the file is named `docker-compose.yml`, which I think is the big gotcha that new users face because this isn't even mentioned by most tutorials. You have to use `docker-compose -f MyFile.yml up` if you want to name your file anything else.

Answer 3

You can open the yaml file using any sort of editor like Notepad++.

Answer 4

To manage and run docker-compose files, you need to install docker compose. Have a look at the documentation to install Docker compose for windows.

Once the installation is done, go to your docker-compose.yml directory and then execute docker-compose to create and start services in your docker-compose.yml file.

Hi,

Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a YAML file to configure your application’s services. 

Compose is basically a three-step process.

1. Define your app’s environment with a Dockerfile so it can be reproduced anywhere.

2. Define the services that make up your app in docker-compose.yml so they can be run together in an isolated environment.

3. Run docker-compose up and Compose starts and runs your entire app.
