Publishing a Kubernetes Service

In Kubernetes, a Service is an abstract way to expose an application running on a set of Pods as a network service

With Kubernetes you don’t need to modify your application to use an unfamiliar service discovery mechanism. Kubernetes gives Pods their own IP addresses and a single DNS name for a set of Pods, and can load-balance across them.

This post will describe the different ways used to publish a Kubernetes service, the risks harbored and the methods that can be applied to mitigate those risks.

The Kubernetes container-orchestration system provides a platform for automating deployments
and operations of application containers across clusters of hosts by defining resources as
manageable Objects. Some of these resources can be managed by other resources automatically
while others can be referenced through metadata fields within the object.

You can never be too safe when it comes to securing your applications. It’s essential that security is a part of the application framework and not just a protective outer layer. Enterprises are swiftly adopting the microservices architecture because of its numerous benefits. However, security still remains a concern. Kubernetes has emerged as the de-facto container orchestration tool. And, on its own, Kubernetes seems to be decent for managing secrets.

Secret-Hunting in Kubernetes

Applications and workloads running on Kubernetes environment, just like any application, requires secrets to gain access to data stored in the database, 1st / 3rd party services or APIs.
Secrets, however, are only effective if they actually remain secret. When secrets leak, attackers will be able to gain access to sensitive data, services or APIs and can potentially put your entire environment and business at risk.
