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.
What is Pod Security Policy?
The Pod Security Policy, sometimes called PSP in short, is a Kubernetes resource that allows the enforcement of policy rules during the creation phase of a Pod.
