<p>So I am following the guide (<a href="https://dev.mysql.com/doc/mysql-operator/en/mysql-operator-installation-kubectl.html" rel="nofollow noreferrer">https://dev.mysql.com/doc/mysql-operator/en/mysql-operator-installation-kubectl.html</a>) to install MySql cluster on a Kubernetes Ubuntu Server 22.04 cluster.</p>
<p>I have run the following commands successfully to import the required yaml deployment files</p>
<pre><code>kubectl apply -f https://raw.githubusercontent.com/mysql/mysql-operator/trunk/deploy/deploy-crds.yaml
kubectl apply -f https://raw.githubusercontent.com/mysql/mysql-operator/trunk/deploy/deploy-operator.yaml
</code></pre>
<p>Now when I then run the deployment command, the pod keeps restarting.</p>
<pre><code>kubectl get deployment mysql-operator --namespace mysql-operator
</code></pre>
<p>Here is the output of the logs (I receive an error)</p>
<pre><code>kubectl logs mysql-operator-755b988dd9-jn7f6 --namespace=mysql-operator
exec /usr/bin/mysqlsh: exec format error
</code></pre>
<p>And here is the describe:</p>

<p>Any help or ideas would be amazing!</p>

<p><code>exec format error</code> usually means the image you are using are not for the architecture you are deploying on. That is, you are using an ARM image on a AMD64 node or vice versa.</p>
<p>Since all of the MySQL images on oracle container registry are AMD64 images, my guess is that your cluster is running on an ARM arch, like an Ampere instance.</p>
<p>You're going to need to run on an x64 arch instance, or find an image for ARM, or go to the source and rebuild the image for ARM.</p>
