Security Gates
  • Trivy container image vulnerability scanning pre-deployment.
  • Gitleaks secret detection enforced as a pre-merge gate.
  • All sensitive values managed via environment variables and secrets managers.
☸
GitOps Delivery
  • Argo CD watches GitOps repo and auto-syncs manifests to Kubernetes cluster.
  • Semantic versioning automated — every PR produces a tagged Docker image.
  • Zero-touch deployments: no manual kubectl steps in the pipeline.
⚡
Pipeline Automation
  • GitHub Actions orchestrates the full pipeline from push to cluster deployment.
  • Docker multi-stage builds minimise image size and attack surface.
  • Automated rollback in Argo CD on health check failures.
📊
Outcomes
  • Fully automated, repeatable deployments eliminating human error.
  • Security vulnerabilities blocked before reaching production.
  • Deployment time reduced from manual hours to automated minutes.
