# Dockerfile pack

> An escape hatch for the local rp CLI

The Dockerfile pack hands off to `docker build`. It's an escape hatch for the [local `rp` CLI](/raypacks/cli) when none of the other packs fit and you already have a working `Dockerfile`.

<Warning>
  This pack does not run on Nubo's managed builders today. Build pods don't have a Docker daemon. Use this only with the local `rp` CLI.
</Warning>

## When it runs

There's a `Dockerfile` at the repo root.

Detection runs top to bottom, and Dockerfile is the last in the list. If you have a `Dockerfile` and a `go.mod`, the Go pack still wins. If you genuinely want the Dockerfile path, delete the other markers or pick the builder explicitly with `rp build --pack dockerfile` (coming soon).

## What it does

The local `rp build` shells out to:

```
docker build -t <tag> <repo-root>
docker push <tag>   # only with --push
```

That's the entire pack. Whatever's in your `Dockerfile` is what ships.

## When to expect a managed Dockerfile path

Daemonless Dockerfile execution (kaniko-style) is on the roadmap. We'll announce it on the [release notes](/release-notes) page when it lands.

In the meantime, if you have a Dockerfile-only repo and need it on managed Nubo:

1. Migrate to one of the auto-detected packs (Go, Node, Static) where possible.
2. Or use the Paketo builder, which has its own Dockerfile-like flexibility through buildpacks.
3. Or run on a [self-hosted agent](/agents/overview) where you control the build environment.
