Terraforming Rancher Deployments on Digital Ocean

November 6, 2017

Having a cool deployment system is pretty neat, but one thing every engineer learns one way or another is that manual processes aren’t processes, they’re chores. If you have to do something more than once, you should automate it if you can.

5 Tips for Making Containers Faster

November 5, 2017

One of the selling points of containers is that containerized applications are generally faster to deploy than virtual machines. Containers also usually perform better.

But just because containers are faster by default than alternative infrastructure doesn’t mean that there are not ways to make them even faster. You can go beyond the defaults by optimizing Docker container image build time, performance and resource consumption. This post explains how. Read more


Checking Out Rancher 2.0 with Kops AWS Clusters

October 27, 2017

One of the hallmark features of Rancher 2.0 is its ability to consume Kubernetes clusters from anywhere. In this post, I’m going to walk you through using the popular kops tool to create and manage Kubernetes clusters on AWS and then bring them under Rancher 2.0 management. This walkthrough will help you create a non-HA Kubernetes cluster, though kops does support HA configurations. With this new cluster, we will run the Rancher 2.0 tech preview in a pod with a persistent volume claim. Read more

It was still BYOLB (bring your own load balancer), and volume management was another manual nightmare. Read more
