The interest in using containers to package applications is constantly growing in the software development community, especially with new technologies such as Kubernetes, Open-shift being adopted more frequently as well. This project also based on modularising the currently adopted monolithic structure and building different micro-services out of it, one such micro- service that defined the goal for this project was building a technical network validating admission controller. Modularising the application increased resilience, provided robust monitoring and no single point of failures. The aim of this project is to build a technical network validating admission controller using Golang deployed in Open-shift that will ensure only whitelisted applications that are visible to the technical network, where the whitelisted applications are assumed to be provided be the security team.
