In this post, I’m going to introduce you to the concept of Linux network namespaces. So what are network namespaces? Generally speaking, an installation of Linux shares a single set of network interfaces and routing table entries. Network namespaces change that fundamental assumption.

As Kubernetes manages other machines and networks, enterprises should continuously strengthen their security postures and take proactive measures to defend themselves. How we got here.
