GitOps K8s sample application deployment with ArgoCD

The app: https://microservices-demo.github.io/

Tested with Kind, an average of 16Gb of RAM required.

Architecture explained:

• The application consists of 10 microservices. Each microservice is deployed with its own Helm chart.
• In a real world scenario, each microservice (code, Dockerfile, Helm Chart, etc..) lives in its own github repo.
• For simplicity in this demo, all application microservices charts are under the folder services

1. Clone the repo
2. Create a cluster with kind
3. Bootstrap the cluster
4. Deploy the application
5. kind delete cluster

How to: Cluster Bootstrap

git clone https://github.com/J0hn-B/eshop.git

kind create cluster https://kind.sigs.k8s.io/

cd ~/eshop/scripts --> chmod +x argocd_install.sh --> ./argocd_install.sh

From a second terminal: cd /eshop/k8s --> kubectl apply -f argo_config

Check your ArgoCD web UI, click sync in the k8s-bootstrap application (you may need to refresh your browser)

In k8s-bootstrap chart, check the templates.
In ArgoCD documetation this is described as "App of Apps" pattern https://argoproj.github.io/argo-cd/operator-manual/cluster-bootstrapping/

How to: Application Deployment

cd ~/eshop/app --> kubectl apply -f argo_config
Check your ArgoCD web UI, click sync in the app-eshop application (you may need to refresh your browser)

Check the github action in .github/workflows/kind.yml.
