WA3235 GitOps Using Flux Training
GitOps is a set of principles that help automate deployment of applications to a Kubernetes cluster. Flux is an open source tool that allows you to implement GitOps in your organization. This course starts by describing what GitOps is and what advantages it has over traditional Continuous Deployment (CD) approaches. It then proceeds to teach you how you can use Flux to implement GitOps.
