Some of those jobs need Docker. A workflow builds an image, runs a service container, or uses the <code>container:</code> key. The usual way to give a self-hosted job Docker is Docker-in-Docker, or dind.</p> <p>The catch is what dind normally costs you. The standard recipe is a <code>--privileged</code> container. Privileged hands the job most of root on the host. For CI that runs fork pull requests, that is a non-starter. A fork PR is a stranger&rsquo;s code.</p>
