+Spring Boot Deploy App
+========================
+During learning Kubernetes or Docker Swarm, I always faced a problem which image should I use for deployment. 
+Most often I used NGINX or just a simple Spring Boot up generated from a scratch. Each time the same, blank boring 
+landing page. Here is my simple tiny application dashboard based on Spring Boot and Bootstrap allows you to test 
+deployment in a few various versions, with a few customized parameters.
