The Phoenix Project

On 11, Oct 2017 | In Audiobooks, Devops | By Manny

I recently got into audio books and became an Audible subscriber. One of the first books I got stuck into was The Phoenix Project by Gene Kim, Kevin Behr, George Spafford.

This is a great book (audiobook). I had so much fun listening to this book in the traffic and on the bus rides into work, I highly recommend it if you are in the IT industry. It’s fast paced listening very funny and dramatic in places.

You should check it out for sure.

What is Kubernetes?

On 26, Dec 2016 | In Devops, Web Development | By Manny

Kubernetes is a very powerful system used for managing containerised software applications in a clustered environment.

It is a command line driven orchestration system developed by Google to manage containerised applications across a cluster of nodes in a cloud architecture environment like Google Cloud Platform.

Pods

A pod is unit managed by kubernetes and you. It is made up of one ore more containers that make up your application.

Services

Services act as a load balancer for other containers.

Services are an interface to a group of containers they provide a single access point.

By deploying a service, you easily get discover-ability and simplify your container design.

Replication controllers

A replication controller helps you manage your containers by allowing you to kill and bring to life new and existing containers.

Horizontally scaled. If a container temporarily dies the replication controller kicks into action a replacement container automatically.

Labels

Is tag that is used for managing your pods by naming them with key value pairs. Its for keeping organised, mostly meta data in file.
