Pipeline flow: local development → GitHub Actions → ECR → ECShttps://elijahu.me/portfolio/projects/orchestration-guide/Sat, 01 Mar 2025 00:00:00 +0000https://elijahu.me/portfolio/projects/orchestration-guide/“Manual deployments are technical debt with compound interest. Every time you run kubectl apply by hand you’re borrowing against future reliability.” This is a full breakdown of a push-to-deploy GitOps pipeline on Kubernetes — Flask webhook orchestration server, isolated test namespace with resource quotas, RBAC scoped to minimum permissions, network policy isolation between test and production, and blue-green deployment with automated rollback. Built because the manual process was unsustainable, documented because the failure modes are worth knowing.https://elijahu.me/portfolio/hng-hultz-journey/Fri, 14 Feb 2025 00:00:00 +0100https://elijahu.me/portfolio/hng-hultz-journey/“Some days you’re debugging code. Other days you’re debugging your life choices. This is a story about both.” Two separate failures ended up in one post because that’s how the month went — back to back, no breathing room. They’re different stories with different lessons, so they’re marked accordingly. You can read one, skip the other, come back. Up to you.
