GitOps

ArgoCD Logo

ArgoCD is used as the declarative continuous delivery solution for the cluster. Based on the GitOps workflow, it provides:

  • Git as the source of truth for the state of the cluster
  • Automated application life cycle management with easy rollbacks and updates
  • Declarative app of apps pattern for easy deployment.

Setup

To setup argo, we need to apply all its CRDs, and create a new namespace with the following command:

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

Then, you can extract the initial password for the admin user from the secret argocd-initial-admin-secret.

kubectl get secret argocd-initial-admin-secret -n argocd -ojsonpath='{.data.password}' | base64 -d

To quickly check the Argo UI, we can port forward the argocd server

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