--- title: Dockerfiles layout: framework_docs objective: Get started by generating a Dockerfile used to build and deploy your application. order: 0 --- The recommended way to deploy Bun, Deno, and Node.js applications is via [Dockerfiles](https://docs.docker.com/engine/reference/builder/). You can provide your own Dockerfile or you can let Fly.io's [dockerfile generator](https://github.com/fly-apps/dockerfile-node#overview) produce one for you. Launching applications on Fly can be as simple as running: ```cmd fly launch ``` In most cases you won't ever need to edit the Dockerfile `fly launch` provides for you directly. Instead you will be able to use one or more of the many [options](https://github.com/fly-apps/dockerfile-node#options) to make changes. For example: ```cmd npx dockerfile --add=dnsutils ```

fly launch

npx dockerfile --add=dnsutils
