GitOps demo

Create a k3d cluster or use existing one

k3d cluster create gitops-demo --agents "1" --agents-memory "4096m"

Install Argo CD

Install Argo CD:

kubectl create namespace argocd
kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml

We suggest that you use our customization to bring back the app of apps sync wave Argo CD feature that was removed in 1.8. You can do this using that command

kubectl apply -k https://github.com/moabukar/gitops-demo/argocd/manifest

Access Argo CD

Wait for the pod to run: it should go fast, but give it a couple of seconds or minutes depending on your computer. You can check the status with

kubectl get pods -n argocd

Once everything is running, make Argo CD UI accessible locally.

kubectl -n argocd port-forward svc/argocd-server 8086:443

Get the admin password:

# Using kubectl
kubectl get secret argocd-initial-admin-secret -n argocd -o jsonpath={".data.password"} | base64 -d

# Using argocd (Argo CD CLI)
argocd admin initial-password -n argocd

Now you can open Argo CD UI. You browser will complain about HTTPS, proceed anyway.

open https://localhost:8080

You can also log into argocd with the CLI

argocd login localhost:8080 --username admin --insecure

Deploy the App of Apps with Sync Waves

You can either deploy the registry using kubectl using

kubectl apply -f https://raw.githubusercontent.com/moabukar/gitops-demo/main/argocd/sync-waves/registry/registry.yaml

Deploy apps reg (optional)

kubectl apply -f https://raw.githubusercontent.com/moabukar/gitops-demo/main/apps/registry.yaml

You can also use argocd if you prefer

argocd app create -f https://raw.githubusercontent.com/moabukar/gitops-demo/main/argocd/sync-waves/registry/registry.yaml
