operations with containers and Kubernetes. The recent Forrester Wave report1 stated that these cloud native technologies are quickly becoming the preferred way for global organizations to build and modernize applications in production by 2022. Confidence of this prediction demonstrated the value of cloud native technologies for developers, who will always look for solutions to help them build applications tools and services Given the transformative impact of Kubernetes and the growth of the cloud native sector, the battle for market leadership in Kubernetes management is very competitive. In December
