GitLab CI AWS OIDC: Replace Static Keys with Short-Lived Credentials
Stop storing AWS access keys in GitLab CI variables. Set up GitLab CI AWS OIDC trust in under 30 minutes and get credentials that expire automatically.
Fix ECR Image Scan Gate Failures in GitLab CI Pipelines
ECR image scan GitLab CI gates fail silently in three distinct ways. Here's how to diagnose each failure mode and wire a hard gate that actually blocks deploys.
AWS Config CI Compliance Gate: Config Rules vs cfn-guard
Your Terraform apply passes but an unencrypted S3 bucket ships to prod anyway. Here's how to pick the right AWS Config CI compliance gate strategy.
How to Fail CI Pipelines on AWS Config NON_COMPLIANT Resources
AWS Config CI pipeline gate that catches NON_COMPLIANT resources before they stay in production — poll compliance after Terraform apply and fail fast.
Hardening Jenkins Agents: Isolate, Restrict, and Verify Your Build Nodes
Default Jenkins agent configuration has several quiet security gaps that can hand an attacker full root on your build host. Here's the layered approach we use to close them.
Ansible Rolling Deployment with Zero Downtime, Batch Control, and Automatic Rollback
Ansible rolling deployments with zero downtime give you fine-grained control over how application updates propagate across a fleet — one batch at a time, with automatic rollback if anything goes wrong. This tutorial walks through inventory structure, HAProxy drain/restore integration, and block/rescue failure handling for production-grade deployments.
Docker BuildKit Cache Optimization for Faster CI Pipelines
Slow Docker builds in CI waste engineering time and inflate infrastructure costs — BuildKit's registry cache backend eliminates redundant layer rebuilds across pipeline runs. This walkthrough covers enabling BuildKit, configuring cache-from and cache-to flags, and wiring everything into a GitHub Actions workflow with verified cache hits.
EventBridge Retry Policies and DLQ Handling in Production on AWS
Silent event loss is one of the most deceptive failure modes in event-driven architectures on AWS. This tutorial walks through configuring EventBridge retry policies and dead letter queues correctly — from IAM permissions to CloudWatch alerting and replay strategies.
Jenkins to AWS Authentication with OIDC: Replacing Static Keys with Federated Identity
Static AWS access keys in Jenkins are a persistent security liability — rotation is manual, secrets sprawl across credential stores, and a single leak can compromise entire environments. This post walks through configuring OIDC federation between Jenkins and AWS IAM so your pipelines authenticate with short-lived tokens and no stored secrets.
Jenkins Shared Library Structure for Reusable CI Pipelines
A Jenkins shared library centralizes pipeline logic in a single versioned repository, eliminating copy-paste Groovy across every team's Jenkinsfile. This post covers directory structure, step conventions, end-to-end consumption examples, and the serialization pitfalls that catch most engineers off guard.
