Kubernetes: GitOps with ArgoCD

Course details

As organizations are moving more and more of their applications to the cloud, the use of manual techniques for provisioning resources is becoming less common, as cloud-native applications use infrastructure-as-code for deployments. In this course, Janani Ravi shows how to use ArgoCD for continuous delivery of infrastructure, so that you’re able to fully automate your application deployment and lifecycle management. Janani shows you how to get started with ArgoCD, then details working with ArgoCD on a local Kubernetes cluster, before showing you how to configure the ArgoCD application. She then covers the steps for deploying infrastructure to an external Kubernetes cluster, and then to Google Kubernetes Engine on the GCP.
