Argo CD Examples

Argo CD Deployment

To follow along Argo CD needs to be installed.

Important

The following can be used to install Argo CD to your cluster:

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

Deployment using Terraform

If you need a Kind Kubernetes Cluster and ArgoCD Deployed, you can look at: server-deployment/terraform

Deployment with Bash and Extras

If you need a kubernetes cluster, gitea and argocd on a kind cluster you can check out: _scripts/bootstrap.sh

Examples

• helm-files-inside-applications
• helm-values-from-file
• git-and-list-generators
  • multiple-tags
• matrix-generators
  • multiple-environment-value-files

helm-values-inside-application

Jump to directory: ./helm-values-inside-application/

The helm values are managed inside the Application:

  source:
    chart: microservice
    repoURL: https://charts.ruan.dev
    targetRevision: 3.1.1
    helm:
      values: |
        replicaCount: 1

helm-values-from-file

Jump to directory: ./helm-values-from-file/

The application is defined in helm-values-from-file/apps/app-dev.yaml and the values are defined in helm-values-from-file/values-dev.yaml and argo will monitor this path on git:

  source:
    path: helm-values-from-file
    repoUrl: https://github.com/ruanbekker/argocd-examples
    targetRevision: HEAD
    helm:
      valueFiles:
      - values-dev.yaml

git-and-list-generators

multiple-tags

Jump to directory: ./git-and-list-generators/

The application is defined in git-and-list-generators/multiple-git-tags-application.yaml and listens for applications in apps/ and does the following:

For staging:

• If the commit tag is staging it will append a staging- prefix to the name and deploy to the staging namespace in the kind-staging cluster.

For production:

• If the commit tag is production it will append a prod- prefix to the name and deploy to the prod namespace in the kind-prod cluster.

matrix-generators

multiple-environment-value-files

Jump to directory: ./matrix-generators/

The ApplicationSet is defined in git-and-list-generators/multiple-envs-applications.yaml and listens for applications under the apps/ directory in the git repository. It uses a git generator to discover application directories and a matrix generator to combine the application paths with environment-specific configurations (dev, staging, production).

For each environment (dev, staging, production), it deploys the corresponding environment-specific values.yaml file using Helm. The deployments are targeted to the appropriate Kubernetes namespaces (dev, staging, production), and the ApplicationSet automatically handles synchronization, pruning, and namespace creation.
