ArgoCon EU 2025 Demo Multi-Cluster at Scale

Setup:

• Install idpbuilder cli https://github.com/cnoe-io/idpbuilder

Run

Deploy clusters:

idpbuilder create --kind-config kind-config.yaml -c argocd:argocd/in-cluster.yaml --use-path-routing -p platform -p vcluster-generator

Web UIs

• ArgoCD: https://cnoe.localtest.me:8443/argocd
• Gitea: https://cnoe.localtest.me:8443/gitea
• Grafana: https://cnoe.localtest.me:8443/grafana
• Prometheus: https://cnoe.localtest.me:8443/prometheus

Grafana username admin password is prom-operator

Get Passwords (ArgoCD, Gitea):

idpbuilder get secrets

Watch mode

As you make changes to yaml files they can be auto sync to gitea run with --no-exit

idpbuilder create --kind-config kind-config.yaml -c argocd:argocd/in-cluster.yaml --use-path-routing -p platform -p vcluster-generator --no-exit

Using vcluster

Connect to a cluster

vcluster connect cluster-0

Disconnect from cluster

vcluster disconnect

Clean

kind delete cluster --name localdev

Appendix

You can use idpbuilder to extract secrets

For example for grafana, label the secret

kubeclt label secret -n monitoring kube-prometheus-stack-grafana "cnoe.io/cli-secret=true"

Extract with idpbuilder

idpbuilder get secrets -o json | jq -r '.[] | select(.name == "kube-prometheus-stack-grafana") .data."admin-user"'
idpbuilder get secrets -o json | jq -r '.[] | select(.name == "kube-prometheus-stack-grafana") .data."admin-password"'
