GitOps is an operational model that allows developers to accelerate the delivery of cloud-native applications that run on Kubernetes.

In this course, you’ll learn the essential principles behind GitOps and how to apply the operational model to modern cloud-native systems. The course provides a detailed description of the relationship between GitOps and technologies like Docker, Kubernetes, and Helm. You’ll gain hands-on experience managing containerized workloads that run on Kubernetes using Flux. Additionally, you’ll explore how GitOps is used to execute progressive delivery strategies with Flagger.

After completing this course, you’ll be prepared to manage the operations of systems using GitOps. You’ll be able to establish and manage the GitOps operational model for systems that run on Kubernetes. You’ll also understand how to install and configure tools like Flux and Flagger that improve your systems' stability and rate of change.

GitOps—Modern Operations for Cloud Native Applications

It determines how to manage cluster workloads using configuration files that are placed on worker nodes in the cluster.

It determines how to manage cluster workloads using custom resource definitions and controllers that can be managed using GitOps.

It determines how to manage cluster workloads by using the JSON configuration stored in a centralized configuration server outside the cluster.

It determines how to manage cluster workloads through additional configuration placed within the manifests of the resources.

Create a new `GitRepository` and commit it to the Flux management repository.

Create a new `kustomization` and commit it to the Flux management repository.

Update the Kubernetes manifests stored within the GitRepository with the new container image and commit the changes to the repository.

Update the Kubernetes manifests with the new container image locally and apply them to the cluster with `kubectl`.

What steps should you take to update one of the container images run by the workloads after establishing a Flux `GitRepository` and `kustomization` resources to manage Kubernetes workloads?
