To avoid conflicts with the local Docker installation, the stack file is named dockhero-compose.yml. Normally you'll place it in the root of your project and put it under version control. It's a regular Docker Compose stack definition - see docker-compose.yml reference for the syntax.

Minimalistic checklist for those who is impatient:


We maintain a repository of pre-defined stacks. You can quickly generate a stackfile via CLI:

heroku dh:generate <stack_name>
