Is there a way to share a configMap in kubernetes between namespaces? : <p>We are using one namespace for the develop environment and one for the staging environment. Inside each one of this namespaces we have several configMaps and secrets but there are a lot of share variables between the two environments so we will like to have a common file for those.</p>

<p>Is there a way to have a base configMap into the default namespace and refer to it using something like:</p>

<pre><code>- envFrom:
    - configMapRef:
        name: default.base-config-map
</code></pre>

<p>If this is not possible, is there no other way other than duplicate the variables through namespaces?</p>
