<p>I'm using a Chromebook Pixel 2, and it's easier to get Rocket working than Docker. I recently installed Rocket 1.1 into /usr/local/bin, and have a clone of the Kubernetes GitHub repo.</p>

<p>When I try to use <code>./hack/local-up-cluster.sh</code> to start a cluster, it eventually fails with this message:</p>

<pre><code>Failed to successfully run 'docker ps', please verify that docker is installed and $DOCKER_HOST is set correctly.
</code></pre>

<p>According to the docs, k8s supports Rocket. Can someone please guide me about how to start a local cluster without a working Docker installation?</p>

<p>Thanks in advance.</p>

<p>You need to set three environment variables before running <code>./hack/local-up-cluster.h</code>:</p>

<pre><code>$ export CONTAINER_RUNTIME=rkt
$ export RKT_PATH=$PATH_TO_RKT_BINARY
$ export RKT_STAGE1_IMAGE=PATH=$PATH_TO_STAGE1_IMAGE
</code></pre>

<p>This is described in the <a href="https://github.com/kubernetes/kubernetes/tree/release-1.1/docs/getting-started-guides/rkt#local-cluster" rel="nofollow">docs for getting started with a local rkt cluster</a>.</p>
