Deploying

Get started with Fly.io.
Create the app with (it'll let you pick a unique name and region):
```
$ flyctl launch --no-deploy --copy-config
```
Note that this command modifies fly.toml - it adds app and primary_region to it; but it also removes comments and changes the actual service setup. Undo these latter changes.
You'll have to create volume(s) named ph_data on every region you'd wish to deploy to:
```
$ flyctl vol create ph_data --region REGION --size 1
```
Allocate a public IP address, so the instance will be reachable:
```
$ flyctl ips allocate-v4  # or allocate-v6
```

Setup the password for the admin panel:

$ flyctl secrets set WBEPASSWORD=a-good-password

Finally,
```
$ flyctl deploy
```
DNS shall be served from APP-NAME.fly.dev over DoT, TCP port 853. The admin panel is available at APP-NAME.fly.dev/admin.
