Service Fabric and mysterious certificates swap

Lately I have been working with microservices deployed in Service Fabric. As officially states: Azure Service Fabric is a distributed systems platform that makes it easy to package, deploy, and manage scalable and reliable microservices and containers. Service Fabric also addresses the significant challenges in developing and managing cloud native applications. Maybe in the future I will create post about differences and commons between Kubernetes and Service Fabric, but today I wanted to focus on simple operational task which is certificates swap.
