Helm Summit 2019

GitOps is a way to do Continuous Delivery, it works by using Git as a source of truth for declarative infrastructure and workloads. For Kubernetes this means using git push instead of helm install/upgrade.

Weave Flux is an open source tool that automatically ensures that the state of a cluster matches the config in git. The Flux Helm Operator provides an extension to Weave Flux that automates Helm chart releases. A chart release is described through a Kubernetes custom resource named HelmRelease. The Flux daemon synchronises these resources from git to the cluster, and the Flux Helm operator makes sure Helm charts are released as specified in the resources.

In this talk, Stefan will discuss the benefits of GitOps and how the Flux community built the Helm Operator. Stefan will demo a GitOps pipeline and perform Helm operations with git commands.
