Implementing Zero Trust Architecture on Kubernetes with GitOps, Istio, and ArgoCD

A practical deep-dive into implementing Zero Trust Architecture on Kubernetes using GitOps delivery and a service mesh. This article walks through the reference architecture end-to-end: GitLab CI with scanning, ArgoCD-driven promotions, JWT-based ingress verification, mTLS and authorization for east-west traffic, Vault-backed secret governance, and continuous verification through metrics and centralized logging.

Branch-Based Promotion in GitHub Actions

Branch-based promotion is a CI/CD strategy where environments map to branches (develop → main) and GitHub Actions deploys based on branch changes, with hard gates enforced via protected branches and GitHub Environments. This guide explains the model, the required GitHub primitives, and provides production-ready workflow templates.
