GitOps Skill

Overview

Specialized skill for GitOps-based continuous delivery using Argo CD and Flux. Provides deep expertise in declarative, Git-driven infrastructure and application deployment.

Capabilities

Argo CD Configuration

• Create and manage Application resources
• Configure ApplicationSet for multi-cluster/multi-tenant
• Set up AppProject for access control
• Implement sync policies and strategies
• Configure resource hooks and waves

Flux Configuration

• Set up GitRepository and HelmRepository sources
• Create Kustomization and HelmRelease resources
• Configure ImageUpdateAutomation
• Implement multi-tenancy with namespaces
• Set up Flux notifications

Sync Strategies

• Configure automatic vs manual sync
• Implement sync windows and freezes
• Set up health checks and degraded detection
• Handle sync failures and retries
• Design progressive delivery patterns

Drift Detection

• Configure drift detection and reconciliation
• Set up resource diffing and comparison
• Implement self-healing policies
• Handle out-of-band changes
• Configure pruning strategies

Secret Management

• Integrate SOPS for encrypted secrets
• Configure Sealed Secrets
• Set up External Secrets Operator
• Implement Vault integration
• Handle secret rotation in GitOps

Multi-Cluster Setup

• Configure multi-cluster deployments
• Implement cluster generators
• Set up cross-cluster sync
• Handle cluster credentials securely
• Design hub-spoke architectures

Target Processes

• cicd-pipeline-setup.js - GitOps-based deployment pipelines
• kubernetes-setup.js - Declarative cluster management
• idp-setup.js - Platform self-service deployment
