<p>Does anyone know how to get a Kubernetes deployment to automatically update when a configMap is changed?</p>

<p>Unfortunately there is nothing built in for this. You used the <code>helm</code> tag, so with Helm you do this by setting a checksum of the rendered configmap (or secret, same issue there) as an annotation in the pod template. This means that changing the configmap results in a (meaningless) change to the pod template, which triggers a rolling update.</p>
