Introduction As part of the HNG Internship DevOps Track Stage 4B, I extended my Stage 4A project — SwiftDeploy — into a fully observable, policy-aware deployment platform. In Stage 4A, SwiftDeploy could: generate infrastructure files from a declarative manifest deploy containers using Docker Compose manage deployment modes (stable/canary) configure Nginx automatically Stage 4B transformed it into something much closer to a real production deployment system by adding: Prometheus instrumentation Open Policy Agent (OPA) policy enforcement live operational dashboards deployment safety gates audit logging and reporting chaos engineering validation The result is a deployment tool that not only deploys services, but also decides whether deployments are safe enough to proceed.
