Maybe docker-compose.yml is empty

Your .yml file must be empty. Try saving the file.

If you have just created your docker-compose.yml chances are you haven't saved it and hit docker-compose up.

Save it and try again. It should work fine

In case of docker-compose.dcproj project check for all the .yml files and nothing should be empty.

  1. docker-compose.override.yml
  2. docker-compose.yml

create file docker-compose.yaml that looks like the below picture and it started working docker.compose.yaml
