How can I open/run a YML compose file on my computer? I've installed Docker for Windows and Docker tools but couldn't figure out how.
To manage .yml files you have to install and use Docker Compose.
Installation instructions can be found here: https://docs.docker.com/compose/install/
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.
If you need more information, take a look to Docker Compose docs: https://docs.docker.com/compose
