Deploy to Fly.io by running `fly launch` for initial setup, configuring your fly.toml with port 8080 and health endpoint settings, then executing `fly deploy` to push your application. Set required secrets with `fly secrets set` before deploying to production environments.

Initial deployment uses `fly launch` to create and configure your app on Fly.io, including setting secrets and health checks. Subsequent deployments use `fly deploy` for updates, which applies code changes without reconfiguring the app infrastructure or resetting secrets.

Troubleshoot deployments by checking app status with `fly status`, viewing logs with `fly logs`, and accessing the running machine via `fly ssh`. Verify health checks are passing and review secret configuration to isolate runtime issues in development and production.

Yes, manage secrets with `fly secrets set` and `fly secrets list` to store environment variables securely. Scale machines with `fly scale` and monitor app availability using `fly open` to launch the deployed application directly from the command line.

Configure fly.toml with a health endpoint, set `auto_stop_machines` to manage idle instances, and specify port 8080 for your application. Fly.io uses these settings to verify app health and automatically suspend machines when not in use, reducing operational costs.
