ArgoCD + Kubernetes: Learn GitOps
Master ArgoCD GitOps with Three Deployment Workflows: Basic, Kustomize & Helm
What You'll Learn
- Implement basic GitOps workflows with ArgoCD application resources and Git repository monitoring
- Scale deployments using Kustomize with base configurations and environment-specific overlays
- Deploy and manage Helm charts through ArgoCD with automated chart upgrades and values management
- Configure sync policies with automated pruning, self-healing, and drift detection capabilities
- Apply enterprise GitOps practices for multi-environment deployments with single source of truth
Description
Master GitOps workflows with ArgoCD through three comprehensive deployment approaches that scale from basic implementations to enterprise-grade solutions. Using a hands-on approach with a pre-configured development environment, you'll implement GitOps principles where your Git repository serves as the single source of truth for your Kubernetes deployments.
Start with the fundamental GitOps workflow by creating ArgoCD application resources that connect directly to your GitHub repository. Learn how ArgoCD continuously monitors your Git repo, automatically detects changes at the HEAD of your main branch, and reconciles any drift between your desired state in Git and the current state in your Kubernetes cluster. Experience the power of declarative deployments where every change to your repository triggers automatic synchronization.
Progress to advanced GitOps patterns using Kustomize for environment-specific deployments. Implement base configurations with development, staging, and production overlays that customize deployments for different environments. Learn to use patches, name prefixes, and environment-specific configurations while maintaining a single source of truth. This approach mirrors enterprise GitOps practices where different environments require different resource specifications.
Explore ArgoCD's native Helm chart support for complex application deployments. Deploy Helm charts directly through ArgoCD, leveraging values.yaml files to configure releases dynamically. Understand how ArgoCD tracks changes to Helm charts and automatically upgrades releases when chart templates or values are modified, providing seamless integration between GitOps workflows and Helm package management.
Each workflow demonstrates key GitOps principles including automated synchronization, drift detection, and declarative configuration management. Learn to configure sync policies with pruning and self-healing capabilities, automatic namespace creation, and continuous monitoring of repository changes.
This comprehensive tutorial prepares you to implement production-ready GitOps workflows using industry-standard tools and practices. Whether deploying simple applications or complex multi-environment systems, you'll master the skills needed to achieve reliable, auditable, and scalable deployment automation.
