A video guide to setup a highly available on-premise Kubernetes Cluster
Setting up an on-premise highly available Kubernetes cluster comes with many challenges. Rancher can help build a production grade cluster. Watch our Certified Kubernetes Administrator Henrik Hoegh set up a cluster and test the deployment.
In this video I will show you how to go from zero to cluster, by provisioning machines and creating a cluster with those virtual machines.
I will be using KVM and libvirt to provision machines locally, and the Rancher Kubernetes Engine to create the Kubernetes cluster.
Managing the cluster will be handled by adding the cluster to a Rancher Server. With the cluster up and running I will show how to use the Eficode Praqma Network Multi Tool to test that the cluster works as intended.
I want to show how little effort is needed to get a Kubernetes cluster running, on premise, in a highly available configuration using state of the art tools.
Helm charts lifecycle management is a manual task. Helmsman allows you to automate your Helm charts lifecycle management using declarative configuration files.

In this post, I’ll take a closer look at the version of Jenkins X using Tekton, to give you an idea of how the general development, build, test, deploy flow looks like with Jenkins X. How does it feel to ship your code to production using a product coming from the Jenkins community that has very little Jenkins in it?

In this blog I will show you how to create snapshots of Persistent volumes in Kubernetes clusters and restore them again by only talking to the api server. This can be useful for either backups or when scaling stateful applications that need “startup data”.

When I read Fowler’s new ‘Refactoring’ book I felt sure the example from the first chapter would make a good Code Kata. However, he didn’t include the code for the test cases. I can fix that!
Writing tests for ‘Theatrical Players’
Nicole Forsgren and the Accelerate DORA team has just released the newest iteration of the State of DevOps report. The report investigates what practices make us better at delivering valuable software to our users as measured by business outcomes. Read on for our analysis of the report, and how it can be best put to use.
The latest drivers of software delivery performance
A major challenge of software development is that our work is by and large invisible. This makes our folklore essential in business matters. Some of our commonly used arguments and visualizations are digital urban legends rather than solid foundations for informed decisions. Here, we’ll go through a few examples and some measures to address our misconceptions.
How the stories we tell influence our decisions
When you embark on your cloud native journey there will be important choices to make about cloud providers, continuous deployment, environments’ setup and separation. This guide will help you make the right choices by sharing lessons learnt from running cloud native apps in production.
Kubernetes has become the de facto container orchestration platform. When we help clients of different sizes and domains start their cloud native journeys in Kubernetes, we assist them in making sound decisions and technology choices. There is no one-size-fits-all solution when it comes to choosing cloud providers, CI tools, continuous deployment pipelines etc., so it is important to make the right decisions at the start. Failing to do so can be very costly in terms of lost time and money.
How to make the right technical choices on your cloud native journey
Learn how Docker and Kubernetes work and the key benefits they bring. Using real demos, I show how Docker is a great packaging and distribution technology, and how Kubernetes provides a powerful runtime for containerized applications.

In the world of Agile and DevOps we use many figures, charts and diagrams to argue and reason about our world and how we prioritize and make choices. However, at all levels of the organization, we misuse and misinterpret figures. It’s time to be explicit, measure the right things and act on them. Watch this talk from DevOpsDays Zurich in May 2019.
