ArgoCD Beyond the Basics

This repository contains practical examples of my blog post called ArgoCD beyond the basics.

Run this locally

To run this locally you only need to install devbox. Devbox is a tool that ensures a consistent developer environment. Devbox will ensure that in your local environment, you will have the following tools:

• Kubectl: Kubernetes command line
• Kind: Kubernetes locally using Docker
• yq: Easily manage YAML manifests

1. Install dependencies

devbox shell

2. Create infrastructure

devbox run create

This will create two local Kubernetes clusters using Kind and install ArgoCD in the local cluster. The cluster called prod is the cluster that ArgoCD will be installed and the dev cluster is the external cluster.

3. Connect to the ArgoCD

devbox run connect

And follow the instructions to connect to the ArgoCD UI.

4. Delete it all when done!

devbox run destroy

To delete the local Kubernetes cluster.

Run the experiments

App of Apps

devbox run app-of-apps

This will create the app of apps pattern.

Multi-Cluster

devbox run multi-cluster

It creates all the Kubernetes resources that allows ArgoCD to deploy to an external cluster (dev cluster).

ApplicationSet

devbox run applicationset

Hooks and sync wave

When you run the app of apps command (devbox run app-of-apps) it automatically creates the example of an application using hooks and sync waves. Notice that this application does not have auto sync, so you can go sync manually on the ArgoCD UI and check the behavior.
