+# Proxy Charms on K8s #

+## Type ##
+**Feature**

+## Target MDG/TF ##
+IM, LCM, N2VC
+
+## Description ##
+Currrently proxy charms are deployed on LXD. This allows us to have these workloads
+running without consuming a lot of resources.Nevertheless with OSM starting to be
+used for production level deployments new methods of deploying these workloads shall
+be considered.
+
+By deploying proxy charms on Kuberentes the deployments will be faster and will ensure
+all the orchestration features already available in a K8s cluster. This will be achieved
+by adding an additional field in the descriptors stating that this proxy charm will be
+deployed on Kubernetes (k8s-proxy-charm). The charm will then be deployed in a Kubernetes
+that must have been added previously with `k8scluster-add` and will operate the same way
+as a proxy charm in LXD.
+
+In the charm implementation the only thing that should change is the charm series in the
+metadata.yaml which will be changed to `series: kubernetes`.
+
+## Definition of done #
+Once this feature is implemented the user will be able to deploy proxy charms on
+kubernetes by changing the above mentioned charm series and setting the k8s-proxy-charm
+field in their descriptors.
