You’ve must heard of this very famous haiku at some point in your career: It’s not DNS There is a no way it’s DNS It was DNS Unfortunately, it was, because we couldn’t test that DNS change. We know that testing infra components can be hard. It is not cheap to have or maintain a test environment for everything or sometimes access to these systems is highly restricted (for good reason!). Also, we often don’t let our infrastructure codebase benefit from CICD practices as our application codebase does, even though it is getting more and more complex each day. We should be aware that no matter how fast we deploy our applications -- if the underlying components are not benefiting from this same process, we’ll only ever be as good as these weaker links. But the good news is, with tools like KubeVirt and Tekton, we can rely on a common platform to test our infrastructure-related deployments and changes (DNS, networking, ansible roles..) safely before pushing things straight to production! And of course, that common platform is Kubernetes! During this talk, we’ll cover how to orchestrate the testing and deployment of the changes safely on Red Hat OpenShift by using Tekton and KubeVirt. We’ll also discuss some of the advantages and disadvantages that may come with an approach like this. Takeaways: * How to apply CICD practices for our infrastructure components * How to execute KubeVirt related steps from Tekton * How to get started and a nice demo
