You should post your issue on sig-openstack. We are focusing on docker-multinode and other approaches to simplify installation. \r\n\r\nWe have created an experimental combination of docker-multinode (with enhancements) and heat. Depending on your requirements this might be a more easy approach towards a running cluster: \r\n\r\nhttps://github.com/FujitsuEnablingSoftwareTechnologyGmbH/k8s-docker-provisioner\r\n\r\n(We are currently merging enhancements back to kube-deploy.)\r\n"}}
