<p>I am trying to create a GitHub actions self-host runner in GKE.
For the I created the Docker with Ubuntu base image and downloaded the GitHub runner code.</p>
<pre class="lang-sh prettyprint-override"><code>curl -o actions-runner-linux-x64-2.288.1.tar.gz -L https://github.com/actions/runner/releases/download/v2.288.1/actions-runner-linux-x64-2.288.1.tar.gz

./config.sh 
</code></pre>
<p>Using the Kubernetes deployment.yaml file deployed the runner in the Kubernetes cluster, but in POD logs I am seeing the below error and the runner is unable to authenticate with the GitHub account.</p>
