With Kubernetes becoming more and more popular, so is managing clusters at scale. Applying GitOps principles with Flux simplifies provisioning clusters and managing workloads deployed onto them, including tenant and RBAC management. In this session I will demonstre a best practice approach towards GitOps with a management cluster handling the provisioning and further maintenance of clusters, tenants and workloads, employing the CNCF projects Flux, OPA Gatekeeper and the Kubernetes Cluster API sub-project. The benefits of such an approach are: * It creates a simplified way to declaratively define thousands of clusters and perform operations on those clusters * Makes it easy to have a multi-tenancy approach where each team or group of applications gets their own cluster or individual namespace on a certain cluster * Operations against clusters are fully audited and attributable, as reverting changes is hard.
