Argo-CD

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 bootstrap-argocd 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
