A Simple CI/CD Workflow Demo

I think every company has its own unique business and tech stack, but when it comes to DevOps, the tools we use are pretty similar. So, let me put together a quick demo of a general CI/CD workflow.

1. Application Repo
2. Reusable workflow repo
3. Infrastructure repo

Application

We just need to input the environment parameter, like “dev/staging/prod” and the parameter namespace, like “hotel” before we trigger the GHA workflow.

Reusable Workflow

This is a common reusable workflow that other microservices are able to call directly.

Terraform Infrastructure

This repo maintains the Terraform code for the public cloud resources.

When we want to update the public product, we need to test in the feature branch first with dry-run mode.

If it works, we can raise a PR to the main branch. Then there is a GitHub issue raised automatically. If the issue is approved by the specific people(it’s better to have more than 2 approvals). Then the change will reflect on the real environment.
