Kubernetes core components

Kubernetes core components

Following on from my first post on the different resources I have used to familiarize myself with containers & Kubernetes I wanted to follow up with a more technical post. In this post I want to cover the core components of a Kubernetes cluster. There are many components within Kubernetes which allow application operators and developers to focus entirely on container-centric primitives for self-service operation. As a network engineer and someone who works on the infrastructure side of I.T some of the deeper…

Kubernetes why should I care about it?

Kubernetes why should I care about it?

As a network engineer why should I care about what the Dev’s are doing with Kubernetes (K8), isn’t it just another service which will consume the network? Just another app on the network? The answer to these questions are both yes and no! After recent involvement in a project which had Kubernetes at the heart of it I was intrigued to learn what it is and what, if any, part a network engineer could play in the world of Kubernetes. This has lead…

AUTOMATION – Part 2 Zero Touch

AUTOMATION – Part 2 Zero Touch

Following on from my first post on automation of network device configurations I think the next easy win for network engineers in automation is a zero touch deployment of network devices. The zero touch deployment feature has been around for many years but from my experience I have never seen it been fully utilized on the network up until recently. Each networking vendor has their own flavor, Cisco has POAP (Power On Auto Provisioning) for their Nexus platofrms & Smart Install for…

Automation – Part 1 configurator

Automation – Part 1 configurator

In the past year we have seen automation take on a new meaning in the networking industry. What use to be feared by most network engineers is been embraced by many. But for a network engineer to move away from the static mindset of configuring device to device through the CLI to a modular approach of building code is not easy. To make this transition easier and remove the fear that some network engineers have of automating themselves out of job one must…

OSPF Areas & Complexity

OSPF Areas & Complexity

Do we care for how complex OSFP could be in our networks? This type of question came up the other day while in work. While we were looking at how OSPF is deployed within our Data Centres today. We keep it simple and mostly a flat network, a few OSPF Areas and one of them been Area 0. Do we have a need to make it complex and add multiple OSPF Areas running in Stub, Total Stub or Not So…
