First create a fly account on [fly.io](http://fly.io/) and install flyctl on your system [fly.io/docs/hands-on/install-flyctl/](https://fly.io/docs/hands-on/install-flyctl/) (on macOS, use `brew install flyctl`)

Then run `fly auth login` to login

Go in your project folder and add a Dockerfile if you don’t have already one.

Then run `fly launch` ([select a region](https://fly.io/docs/reference/regions/) that’s free) and `fly deploy --ha=false` to create a single-instance free service.
