What can we achieve with ArgoCD?

With ArgoCD, declarative, GitOps-oriented deployment of applications and configuration management in Kubernetes is achieved. Main features:

• Automated deployment: Synchronization of cluster state with Git repository.
• Visualization and monitoring: Visual representation of application status and change history.
• Rollback: Easy recovery to a previous working state.
• Synchronization: Support for various synchronization strategies (Manual, Automatic).
• Multi-cluster management: Deployment across multiple Kubernetes clusters from a single location.
• Integration: Compatibility with Helm, Kustomize, Jsonnet, and standard YAML manifests.
• Security: Role-based access control model.

Example of a declarative application description:

// app.yaml
apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: my-app
spec:
  destination:
    namespace: default
    server: https://kubernetes.default.svc
  project: default
  source:
    path: guestsbook # Path to manifests in Git repository
    repoURL: https://github.com/argoproj/argocd-example-apps.git
    targetRevision: HEAD
  syncPolicy:
    automated:
      prune: true # Remove resources not in Git
      selfHeal: true # Automatically restore discrepancies
