<p>I'm trying to run gitlab-runner on my kubernetes cluster on raspberry pi. </p>

<p>The gitlab pipeline generates the following output:</p>

<pre><code>Running with gitlab-runner 10.4.0 (857480b6) on hello-world-gitlab-runner-6548-tq4mr (123)

</code></pre>

<p>The gitlab-runner pod logs the following output: </p>

</code></pre>

<p>Any idea to fix this? </p>

<p>I managed to specify helper container version (my runner was configured with <a href="https://docs.gitlab.com/runner/install/kubernetes.html" rel="noreferrer">helm chart</a> and <a href="https://docs.gitlab.com/runner/install/kubernetes.html#additional-configuration" rel="noreferrer">values.yaml</a>) - official image supports ARM</p>

<pre><code>runners:
  helpers:
    image: gitlab/gitlab-runner-helper:arm-latest
</code></pre>
