+
+NEXUS repository for kubernetes to deploy on a kubernetes cluster with NFS-share
+
+## Containers

+
+- OpenCPU
+- MOLGENIS-httpd (to proxy the registry and docker to one domain)

+## Provisioning
+You can choose for the OpenCPU image from which repository you want to pull. Experimental builds are pushed to registry.molgenis.org and the stable builds to hub.docker.com. 
+You need to fill out 2 properties to determine which repository you are going to use.
+
+- ```opencpu.image.repository```
+- ```opencpu.image.tag```
+
+You can do this in the questions in Rancher or in the ```values.yaml```.
+
+
+
+## Development
+You can test in install the chart by executing:
+
+```helm lint .```
+
+To test if your helm chart-syntax is right and:
+
+```helm install . --dry-run --debug```
+
+To test if your hem chart works and:
