Argo CD is an open-source GitOps continuous delivery tool for Kubernetes. In GitOps, all deployment manifests live in a Git repo as the source of truth. Argo CD continuously monitors the Git repo and the Kubernetes cluster, and automatically (or manually) syncs the live state to match the desired state in Git. It also provides a web-based UI to see “desired vs live” status of your applications. In this tutorial, we’ll install Argo CD on a local Minikube cluster, access the Argo CD web UI, and deploy a sample GitOps application (a simple NGINX example) from a public repository.
