Argo CD is a Kubernetes-native, declarative GitOps tool for deploying applications at scale. It pulls application manifests directly from a Git repository and syncs them to a Kubernetes cluster, supports YAML, Kustomize, Jsonnet, and Helm, and ships with a built-in web UI for monitoring sync status and application health. This guide installs Argo CD on a Kubernetes cluster, sets up access to its web UI and CLI, and deploys applications through both a YAML manifest and the Argo CD dashboard. By the end, you'll have Argo CD running behind TLS with two applications deployed and synced through it.
Before you begin, you'll need access to a Kubernetes cluster with at least three nodes, a Linux-based local or remote instance to test the Argo CD CLI, the kubectl CLI installed and configured on your local machine, the Helm client installed locally, and a domain name for your Argo CD installation (for example, argo.example.com).
1. Install Argo CD
1. Create a namespace for Argo CD:
$ kubectl create namespace argocd
