#### The `web` process
For initial app deploys, Dokku will default to starting a single `web` process for each app. This process may be defined within the `Procfile` or as the `CMD` (for Dockerfile or Docker image deploys). Scaling of the `web` process - and all other processes - may be managed via `ps:scale` or the `formations` key in the `app.json` file either before or after the initial deploy.
