Dev-Ops

What is it?

It is a project that is part of lazy-stock-screener which is a full-stack micro-service prototype product. This repository is also called umbrella project. Leveraging gitlab.ci, I build various kind of image for building image, which later is pushed to gitlab container registry.

Why did I share this project in public?

The full product is still under constructing and the full product is committed to gitlab. I only share part of the use-case in order to demonstrate how I built up the stock-server.

What features do this project have?

• Leverage docker-compose for building databases and services
• Leverage gitlab runner to deploy container from gitlab container registry to GKE.
• Build auto-deploy script image that contains istioctl and helm for other CI pipeline.
• Subchart pattern in Helm
• Instead of constructing project with submodule, setting .gitignore to ignore nest project folder.
