ArgoCD

Gitops model for Kubernetes using ArgoCD
Argo-CD

Organization

  • gitops/argocd/bootstrap : Argo-CD deployment
  • gitops/argocd/stacks : Portefaix stacks : Argo-CD projects and applications
  • gitops/argocd/apps/<CLOUD>/<ENVIRONMENT> : Argo-CD applications deployed into the Kubernetes cluster
  • gitops/argocd/charts : Helm charts configurations

To configure the Helm charts, we use YAML files :

  • values.yaml: common configuration to all Kubernetes cluster
  • values-<CLOUD>-<ENVIRONMENT>.yaml : configuration of the Helm chart for a Kubernetes cluster

Bootstrap

Argo-CD

❯ make argocd-bootstrap ENV=<environment> CLOUD=<cloud provider> CHOICE=helm

Stacks

Install a stack into the cluster:

❯ make argocd-stack-install ENV=<environment> CLOUD=<cloud provider> STACK=<stack name>

Stacks:

  • Core
  • System
  • Networking
  • Security
  • Observability
  • Chaos
  • Tools
