<p>I am looking for best option in handling DEV, TEST, CERT and PROD environments in Kubernetes.</p>

<p>You can use namespaces in Kubernetes. Create one namespace per environment.</p>

<p><a href="http://kubernetes.io/docs/user-guide/namespaces/" rel="nofollow">http://kubernetes.io/docs/user-guide/namespaces/</a></p>

<p>Once things get more involved, you can may be move to one cluster per environment, or something like DEV, TEST in a cluster and CERT and PROD in their own clusters.</p>
