GitOps your kubernetes deployments with Helm and Helmsman

Helm (an incubated CNCF project) is the kubernetes package manager which allows you to parametrize, version and publish your kubernetes applications. However, Helm is NOT the kubernetes CI/CD tool. And that’s why we created Helmsman.

We use Helmsman to automate the lifecycle management of Helm releases in k8s clusters using a declarative desired state. The desired state describes how we would like to setup the cluster and deploy the applications. By version controlling our desired states and using a CI tool we can achieve GitOps ( in plain English: trigger changes from git commits).

In this talk, I will explain why we need Helmsman, how it works and how it can be used together with CI tools to achieve GitOps. I will run a demo using Google Kubernetes Engine (GKE) and CircleCI (though any k8s provider and CI tool will work the same).
