ArgoCD App of Apps demo

This repo contains a basic implementation of the App Of Apps Pattern for ArgoCD.

It is be possible to test the setup on a local machine using minikube.

Install ArgoCD on minikube

Start minikube and use max available resources:

minikube start --memory=max --cpus=max

Install ArgocCD:

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

Access UI

Use Port Forwarding to access the UI server:

kubectl port-forward svc/argocd-server -n argocd 8080:443

Open a browser and go to http://localhost:8080.

Use the admin user to login. The password can be retrieved using the following command:

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

Install CLI

https://argo-cd.readthedocs.io/en/stable/cli_installation/

Install Demo App of Apps

Login using the CLI:

argocd login localhost:8080 

The same UI credentials can be used.

Create all applications of the test environment:

argocd app create apps \
    --dest-namespace argocd \
    --dest-server https://kubernetes.default.svc \
    --repo https://github.com/jgoelen/argo-app-of-apps-demo.git \
    --path apps/test

Appendix

Create Sealed Secrets

Use Port Forwarding to access the Sealed Secret controller:

kubectl port-forward svc/sealed-secrets -n kubeseal 8090:8080

Encrypt a secret using kubeseal:

echo -n 'My secret' | kubeseal  --cert http://localhost:8090/v1/cert.pem --raw --from-file=/dev/stdin --namespace demo --name demo-secrets
