Solo-built production GitOps platform on AWS EKS
An infrastructure engineer documented building a production-style GitOps platform on AWS EKS around the Spring PetClinic microservices (7 services). The platform is fully provisioned with Terraform (remote state on S3 + DynamoDB) and uses GitHub Actions with OIDC to build Docker images and push to Amazon ECR. CI bumps image tags in a Helm values-driven chart; Argo CD reconciles the cluster (git as source of truth). Autoscaling is implemented at two layers (HPA for pods and Karpenter for nodes). Observability is provided by Prometheus, Grafana and Zipkin. The project is reproducible via a Makefile (provision, up, down). The author describes several production issues and fixes (tracing misconfiguration, CI tag mismatches, Argo CD vs HPA replica conflict, Karpenter IAM policy size) and publishes the infrastructure and app repos and a live demo URL.
Blue-Green Deployment Pipeline on AWS EKS
A hands-on walkthrough demonstrating how to build a blue-green deployment pipeline on AWS EKS using Ubuntu and a terminal. The author provides exact commands, Kubernetes manifests, a multi-stage Dockerfile, and a GitHub Actions workflow that automates building, pushing to Amazon ECR, deploying to an idle environment, performing an internal health check, and switching traffic by patching the Service selector. The pipeline averages 29 seconds end-to-end, the traffic switch is under one second, and rollback under five seconds. The article also documents practical AWS-specific fixes (ELB hostnames, ECR node IAM policy), debugging tips, and a public repository (github.com/gbadedata/zero-downtime-bluegreen-eks). Recommended next steps include Prometheus/Grafana, canary releases, Terraform, and automated rollback triggers.
Enforce Kubernetes Image Provenance with Cosign & Kyverno
A developer experiment demonstrates enforcing image provenance in Kubernetes so the cluster only runs cryptographically signed container images. The workflow uses GitLab CI/CD as the build-and-trust origin, Cosign/Sigstore to sign and publish OCI image signatures, an OCI registry to store images and signatures, and Kyverno as a Kubernetes admission controller to verify signatures and enforce policies. The author tested the approach on a local MicroK8s cluster, published example GitLab pipeline snippets and a Kyverno ClusterPolicy that resolves image digests, fetches Cosign signatures from the registry, and allows or rejects Pod creation based on verification. A reference GitHub repository with code and configs is provided.
