- Now Kubernetes Cluster murano application provides ability to install
Kubernetes Dashbord addon v1.4 during cluster deployment.
Dashboard (the web-based user interface of Kubernetes) allows user
to deploy containerized applications to a Kubernetes cluster, troubleshoot
them, and manage the cluster and its resources itself.
User can find dashbord endpoint in deployment logs.
