The docker compose file is quite simple if you ignore traefik and its related labels. Traefik allow us to use HTTPS. WARNING: Note that is you connect this project to a custom domain, you’ll have the modify the “url” environment variable, to make it match the name of the custom domain. By default, it’s value is https://${CRANE_IT_EB_DOMAIN}, (the elastic beanstalk domain).
