Dockerfile not found

Error message

Dockerfile not found: ${dockerfilePath}

What it means

When the requested features include 'docker', machine.mjs requires the repo's Dockerfile at ../.buildkite/Dockerfile (resolved relative to the script's own directory) and throws if it is missing. The absolute path is printed in the message.

Solutions

1. Check the path from the error message with `ls`
2. Restore it: `git restore .buildkite/Dockerfile` (or merge upstream if it moved)
3. Omit the docker feature if this run does not need a Docker-equipped machine

import { existsSync } from "node:fs";

const dockerfilePath = new URL("../.buildkite/Dockerfile", import.meta.url);
if (features.includes("docker") && !existsSync(dockerfilePath)) {
  throw new Error("docker feature requested but .buildkite/Dockerfile is absent from this checkout");
}

When it happens

Trigger: Requesting the docker feature in a checkout that lacks the .buildkite directory — sparse checkouts, moved script copies, or after the Dockerfile was renamed upstream while your branch predates it.

Common situations: Sparse CI checkout excluding .buildkite/; running a fork where the Dockerfile was deleted; branch drift after build infrastructure files moved.
