ArgoCD Configuration
Deployed ArgoCD via Helm chart with Application of Applications pattern, enabling automated deployment synchronization across multiple Kubernetes clusters with Git-based configuration management.
- ▸Application of Applications pattern for scalable management
- ▸Multi-cluster management with centralized control
- ▸Automated sync policies for continuous deployment
- ▸RBAC and security controls for access management
- ▸Webhook integration for real-time updates
- ▸Health checks and automatic rollback capabilities
Image Updater Integration
Configured ArgoCD Image Updater to automatically detect and update container images from registries, creating pull requests for image tag updates with configurable update strategies.
- ▸Registry polling configuration for automatic image detection
- ▸Update strategies (semver, latest, digest-based)
- ▸Automated PR creation for image tag updates
- ▸Rollback capabilities for failed deployments
- ▸Multi-registry support (ECR, Docker Hub, GCR)
- ▸Update policies and filters for controlled updates
Multi-Cluster Setup
Managed three Kubernetes clusters (Production, Staging, Development) from a single ArgoCD instance using Kustomize overlays for environment-specific configurations.
- ▸Production cluster for live customer traffic
- ▸Staging cluster for pre-production testing
- ▸Development cluster for experimentation
- ▸Kustomize overlays for environment-specific configs
- ▸Centralized management from single ArgoCD instance
- ▸Consistent deployment patterns across environments
Security & Best Practices
Implemented comprehensive security controls including RBAC policies, container image scanning, and vulnerability assessments to ensure secure GitOps workflows.
- ▸RBAC policies for ArgoCD access control
- ▸Service account permissions with least privilege
- ▸Cluster role bindings for namespace isolation
- ▸Container image scanning and vulnerability assessments
- ▸Signed image verification for trusted sources
- ▸Registry access controls and authentication
Automated Deployment Pipeline
Established complete GitOps workflow from code push to production deployment with automated image updates and synchronization across clusters.
- ▸Code pushed to Git repository triggers CI/CD pipeline
- ▸CI/CD builds and pushes Docker images to registry
- ▸Image Updater detects new images and creates PR
- ▸ArgoCD syncs changes to target Kubernetes clusters
- ▸Health checks and automatic rollback on failure
- ▸Zero-downtime deployments with rolling updates
