VSHN.timer #29: Configuration & Infrastructure as Code
Welcome to another VSHN.timer! Every Monday, 5 links related to Kubernetes, OpenShift, CI / CD, and DevOps; all stuff coming out of our own chat system, making us think, laugh, or simply work better.
This week we are going to talk about different tools and techniques to declare and configure infrastructure as code.
1. CfgMgmtCamp Ghent 2020 just ended (how do you even pronounce the name?) so let’s talk configuration. As explained by Adrien Trouillaud, “There are two basic ways to deploy to Kubernetes: imperatively, with the many kubectl commands, or declaratively, by writing manifests and using
kubectl apply.” Of course in VSHN we’re great fans of infrastructure as code and GitOps, and our upcoming Project Syn is all about that.
3. In the same vein as jk, the Dhall configuration language proposes a mechanism to create a “single source of truth” for all of our configuration needs.
4. If you work with Kubernetes (who doesn’t these days?) you will find KUDO and Tanka to be useful additions to your toolbelt. The former is a toolkit to build Kubernetes Operators using plain YAML, while the latter is composable configuration utility based on Jsonnet.
5. For those working with cloud providers such as Azure, Google Cloud, or AWS, you might want to try out Gyro and Checkov. Gyro abstracts all infrastructure with an ad-hoc configuration language, while Checkov provides ready-to-use best practices and policies to apply in major cloud environments. But whatever tool you use for your configuration, whatever your environment, remember:
Note to self: Don’t deploy on Fridays
