<p>I have a MySQL database pod with 3 replicas.<br>Now I'm making some changes in one pod(pod data,not pod configuration), say I'm adding a table.<br>How will the change reflect on the other replicas of the pod?</p>

<p>I'm using kubernetes v1.13 with 3 worker nodes.</p>

<p>PODs do not sync. Think of them as independend processes.</p>

<p>If you want a clustered MySQL installation, the Kubernetes docs describe how to do this by using a StatefulSet: <a href="https://kubernetes.io/docs/tasks/run-application/run-replicated-stateful-application/#deploy-mysql" rel="nofollow noreferrer">https://kubernetes.io/docs/tasks/run-application/run-replicated-stateful-application/#deploy-mysql</a></p>

<p>In essence you have to configure master/slave instances of MySQL yourself.</p>
