How To Dev

Introduction DevOps is a combination of development (Dev) and operations (Ops), aimed at uniting people, processes, and technology to enhance the software development lifecycle. Here are some key aspects of DevOps: Collaboration and Communication: DevOps fosters a culture where development, IT operations, quality engineering, and security teams work together seamlessly. Continuous Integration and Continuous Delivery (CI/CD): These practices automate the integration and delivery of code changes, ensuring faster and more reliable software releases¹. Infrastructure as Code (IaC): This approach involves managing and provisioning computing infrastructure through machine-readable scripts, rather than physical hardware configuration¹. Monitoring and Logging: Continuous monitoring and logging help teams to detect issues early and maintain system reliability. Automation: Automating repetitive tasks reduces errors and increases efficiency, allowing teams to focus on more strategic work. By imple

Introduction Kubernetes (often abbreviated as K8s ) is an open-source system designed to automate the deployment, scaling, and management of containerized applications. This page serves as a collection of articles related to Kubernetes (K8s) , including theoretical concepts and practical guides on using Kubernetes to set up essential tools for the software development process. I will continue to update this series with new articles as ideas come to mind, to ensure the series becomes more comprehensive. The articles are arranged in increasing order of difficulty to make it easier for you to follow. If you have time, it's recommended that you start from the beginning of the series to acquire the necessary knowledge and information that will prepare you for the subsequent articles. Key Topics Covered in This Series Basic Knowledge : Fundamental concepts, common commands, etc. Resources : Pod, Deployment, Service, StatefulSet, Ingress, etc. Pod Autoscaler : Horizontal vs. Vertical sc

Introduction Docker is an open platform for developing, shipping, and running applications. This page is dedicated to compiling articles related to Docker , covering both the theoretical aspects and practical applications of Docker in setting up popular tools essential for software development. I will be updating this series with more articles in the future as new ideas for topics arise. The articles are arranged in increasing order of difficulty, making it easier for you to follow along. If you have the time, I recommend starting from the beginning of the series to ensure that you grasp the necessary knowledge and information needed for the more advanced articles later on. Here are some key topics in the series that you need to explore to effectively use Docker : Basic knowledge Docker commands Docker Compose Building Docker images Performance improvement Integration with CI/CD Once you have a solid understanding of the foundational knowledge, the extended topics (including advanced

Introduction NodeJS is an open-source and cross-platform JavaScript runtime environment . Here are some key points about NodeJS : V8 Engine : NodeJS runs on the V8 JavaScript engine , which is also the core of Google Chrome . This allows NodeJS to be highly performant. Asynchronous and Non-Blocking : NodeJS  uses an event-driven, non-blocking I/O model. It’s lightweight and efficient, making it ideal for data-intensive real-time applications. Single-Threaded : NodeJS  runs in a single process, handling multiple requests without creating new threads. It eliminates waiting and continues with the next request. Common Language : Frontend developers who write JavaScript for browsers can use the same language for server-side code in NodeJS . You can even use the latest ECMAScript standards without waiting for browser updates. This page is designed to compile articles related to NodeJS , including how to integrate it with various libraries and relevant tech stacks. I will continue to u

Introduction Gitlab is a comprehensive platform designed for software development and version control using git. It provides a user-friendly web interface that enhances the speed of working with git, making it easier to manage Git repositories. Gitlab  offers a range of features including: Free public and private repositories: You can host your code securely and privately or share it with the world. Continuous Integration/Continuous Deployment (CI/CD) : Automate the testing and deployment of your code. Free private docker image storage on Container Registry In this article, I'll guide you on how to push a Docker image to the Gitlab Container Registry and set up CI to automatically build and push Docker images when you push code to a Gitlab repository. Pushing a Docker Image to the Gitlab Container Registry First, you'll need a Gitlab account and a repository (either public or private will work). Use the NodeJS Typescript Server project I introduced earlier , or any proj

Introduction Continuous Integration (CI) : This is the process of building, testing, and performing necessary actions to ensure code quality before it gets merged into the main branch for deployment. Continuous Delivery (CD) : This usually happens after CI and includes steps to deploy the source code to various environments like staging and production . This guide will show you how to set up CI/CD on Github using Google Cloud Build . While Github provides shared runners, if you or your organization have many jobs that need executing during development, setting up your own runner is a better choice. Before proceeding, you should understand some basics about Google Cloud Run to build and deploy Docker images. You can refer to this article for more details: Build Docker image for NodeJS Typescript Server . Setting Up GitHub CI/CD First, create a Github repository. You can choose either a public or private repository. You can use a NodeJS TypeScript application, following my guide o
