Hacking Kubernetes on AWS (EKS) from a Mac

Hacking Kubernetes on AWS (EKS) from a Mac

While working with a client recently, we experienced some issues when attempting to make use of NLB external load balancer services when using AWS EKS. I wanted to investigate whether these issues had been fixed in the upstream GitHub Kubernetes repository, or if I could fix it myself, contributing back to the community in the process.

The particular Kubernetes code in question is in the part of the repository responsible for communicating with the AWS EC2 APIs. This lies entwined with the kube-controller-manager which runs on the masters. This meant I wasn’t able to use EKS directly to test the changes as the EKS master nodes are not able to be controlled or upgraded by users. Instead I needed to run the masters myself and essentially simulate EKS. As long as these simulated masters resided somewhere in AWS, I would be able to accurately test the AWS integration. I thus needed to build, package, deploy & test Kubernetes for AWS from the Kubernetes Git repository – this blog records the travails and steps of what is required to do this.

ContainerSched 2015 – Call for Papers Now Open!

ContainerSched 2015

ContainerShed 2015Over the last few years there has been exponential growth in the interest of containers and schedulers – technology such as Docker, rkt, Mesos, and Kubernetes are now commonplace within the IT domain, and with the rise of microservices, these technologies are set to become even more popular. Skillsmatter are keen to drive forward the discussions and knowledge sharing within this area of technology, and have created a conference focused exclusively on containers and schedulers: ContainerSched!

Embracing Disruptive Innovation: OpenCredo Partners with Google

Why OpenCredo partnered with Google

Recently OpenCredo chose to partner with Google in order to share knowledge and resources around the Google Cloud Platform offerings. Our clients come in many shapes and sizes, but typically all of them realise three disruptive truths of the modern IT industry: the (economic) value of cloud; the competitive advantage of continuous delivery; and the potential of hypothesis and data-driven product development to increase innovation (as popularised by the Lean Startup / Lean Enterprise motto of ‘build, measure, learn’).
