The DevOps Odyssey: Fully Automating OCI App Deployment with Terraform, Ansible, and Docker

Introduction: The Engineer's Drive for Automation

As a DevOps engineer, I thrive on full‑stack automation—turning repetitive, error‑prone deployments into push‑button, ultra‑reliable workflows.
I recently challenged myself to get Job Winner, an opensource full‑stack app (Spring Boot + React), live on Oracle Cloud Infrastructure (OCI) in less than 15 minutes from a cold start.
But the real goal wasn't speed alone—it was idempotence: every run of the pipeline should converge the system to the exact same, secure, HTTPS‑enabled state without manual touch‑points.

Github repository dispatch

Background

I have to run a shell script at repo B from repo A which hosts a python app. While I can spend the time to reinvent the wheel and fork the logic into python, it is best to keep thing simple by reusing what is already out there and proved to be working fine.

The js script in repo B is already wired up with a Github workflow. What if I can kick off that workflow remotely from repo A?

Github repository dispatch is the answer.
