About
Introduction
Inspired by the recent interview conversation, I decided to synthesize and expand my interdisciplinary knowledge and try my hand at the DevOps approach. The impact of this culture is visible not only in software delivery but also in data processing and analysis (DataOps), infrastructure management (GitOps), and improving the reliability of production environments (SRE). I consider it a valuable lesson and an excellent complement to my previous projects.Objective
A cross-sectional CI/CD pipeline project using a modern technology stack.
Integration of various tools and techniques.
I will try to create a complete environment to integrate development tools, automatically trigger processes, test the application, create a release image, and deploy a simple backend application along with the database schema to the server.
I treat this as a Pet Project or a study, so I will be integrating additional components over time.
Components:PS
All tools are self-hosted on my local infrastructure (using Docker, Debian etc.) because my VPS, which hosts other projects, lacks the resources to handle everything :)
I'm also working on enhancing my lab environment's security before enabling port forwarding, to ensure safe and controlled access to my services.For educational purposes, I prefer a "longer way" to deeply understand infrastructure concepts and implementations. When time-to-market isn't critical or when the overhead of maintainability isn't a major concern, I remain cloud abstraction layer agnostic.
Still, I recognize the value of cloud platforms for simplifying infrastructure through intuitive interfaces, managed services etc.Recently, I attended a Google Cloud Platform Meetup, which furthered my interest in cloud technologies. I'm planning cloud-based projects soon, aiming to leverage these platforms effectively once I've mastered the fundamentals.
