<p>Checking the latest image used in the metrics-server <a href="https://github.com/kubernetes-sigs/metrics-server/releases/tag/v0.5.0" rel="nofollow noreferrer">Github repo</a>, the tag used is <strong>v0.5.0</strong>, for arm64 I would usually add <em>arm64</em> to the image name and pull it.</p>
<p>But the image doesn't exist and doing an inspect to the base image shows that its arch is <em>amd64</em>.</p>
<p>In <a href="https://console.cloud.google.com/gcr/images/google-containers/global/metrics-server" rel="nofollow noreferrer">google's registry</a> the latest image is <code>v0.3.6</code>. So I'm not sure if support for arm64 has continued or staled.</p>

<p>There's no need to append <em>arm64</em> starting v0.3.7, the image support multiple architectures. See official FAQ <a href="https://github.com/kubernetes-sigs/metrics-server/blob/master/FAQ.md#how-to-run-metric-server-on-different-architecture" rel="nofollow noreferrer">here</a> with complete image url.</p>
