Section Directory

1. Templating & Patching

• Helm Chart Masterclass: 10-part comprehensive guide covering chart creation, templating, lifecycle hooks, dependencies, OCI distribution, and testing.
• Kustomize: Native declarative overlay and patch management without template engines.

2. GitOps Continuous Delivery

• GitOps Fundamentals: Principles of GitOps, push vs pull reconcilers, drift detection, and state reconciliation.
• Argo CD Guide: Production Argo CD patterns, ApplicationSets, multi-tenancy, and sync policies.

3. Progressive Delivery & Workflows

• Argo Rollouts: Canary deployments, blue/green switching, automated analysis, and metric-based rollbacks.
• Argo Workflows: Kubernetes-native batch and workflow engine for CI/CD tasks.
• CD Integration: Connecting GitHub Actions, GitLab CI, BuildKit, Kaniko, and image signing into Kubernetes pipelines.
