In the dynamic realm of software development, particularly within agile and cloud-native landscapes, the ability to swiftly adapt and innovate is paramount. This agility, however, often comes with its own set of challenges, especially when it involves the coordination and management of numerous microservices and processes. Herein lies the crux of our narrative: the establishment of a robust developer platform, metaphorically dubbed “The Show” for its ability to seamlessly present the final act to the audience — our customers — without exposing the countless hours and effort invested backstage by developers and operations personnel.

Background on why I’m writing this series

Part of my role at Tikal requires me to interview candidates for DevOps / SRE / Platform Engineers, nowadays in the center of any modern application we have kubernetes and considering kubernetes has many extensions in the form of controllers and operators, one of the questions I like asking is — give me an example of 5 controllers or operators you used / will use when setting up a new kubernetes cluster, this post will attempt to answer that question as much as possible tackling the core challenges we meet when setting up and running an application on kubernetes.

As we continue to build our production grade cluster, we should explore the central components of Kubernetes, one of it’s core features is service discovery which is achieved by using DNS, this sub-system is fundamental for understanding how applications communicate with one other, and are how they are made accessible externally. This part of the series will start by diving into the internal mechanisms of service discovery, and then expand on how Kubernetes integrates with external DNS systems for service accessibility which will also prepare us for part 4 which will discuss ingress traffic.ֿ
