ABSTRACT OF THE TALK

Welcome Helm users! CNCF Flux has a best-in-class way to use Helm according to GitOps principles. For you, that means improved security, reliability, and velocity - no more being on the pager on the weekends or having painful troubleshooting or rollback when things go wrong.

Built on Kubernetes controller-runtime, Flux’s Helm Controller is an example of a mature software agent that uses Helm’s SDK to full effect.

Flux’s biggest addition to Helm is a structured declaration layer for your releases that automatically gets reconciled to your cluster based on your configured rules:
⭐️ The Helm client commands let you imperatively do things
⭐️ Flux Helm Custom Resources let you declare what you want the Helm SDK to do automatically.

In addition, Scott will show how to use Helm Charts to run reliable stateful workloads.

If you want to follow along with Scott’s demo, here are a couple of resources to help you prepare ahead of time:
