How to: Exposing Gatus on a custom port
By default, Gatus is exposed on port `8080`, but you may specify a different port by setting the `web.port` parameter:
```yaml
web:
  port: 8081
```

If you're using a PaaS like Heroku that doesn't let you set a custom port and exposes it through an environment
variable instead see [Use environment variables in config files](#use-environment-variables-in-config-files).
