Github-Actions

Deploying to Kubernetes manually is slow and error-prone. Every deploy requires building an image, pushing it to a registry, and updating the cluster. With CI/CD, all of that happens automatically on every push to your main branch. Write code, push to GitHub, and your new version is live in minutes — with zero-downtime rolling updates. This tutorial builds a complete pipeline with GitHub Actions. The Pipeline Overview Developer pushes code to main branch ↓ GitHub Actions triggers workflow ↓ Build Docker image ↓ Push image to registry (GHCR or Docker Hub) ↓ Deploy to Kubernetes (kubectl apply or helm upgrade) ↓ Wait for rollout to complete ↓ Done — new version is live Prerequisites A Kubernetes cluster (for this tutorial, we use a real cluster — not minikube). Options: k3s on a VPS, or any cloud provider. A GitHub repository with your app code and Kubernetes manifests Basic understanding of GitHub Actions (jobs, steps, secrets) Step 1: Prepare the Kubernetes Manifests Keep your Kubernetes YAML files in your repository, under a k8s/ directory: ...

You push code. Tests run automatically. The App Bundle (AAB) is built and signed. It gets uploaded to the Play Store internal track. You never touch the build machine. This is CI/CD — Continuous Integration and Continuous Deployment. It saves hours of manual work and catches bugs before they reach users. In this tutorial, you will set up a complete CI/CD pipeline for your Android app using GitHub Actions and Fastlane. ...

In the previous tutorial, we learned to merge and rebase branches. But everything happened on your local computer. Real projects involve multiple people working together. This is where GitHub comes in. GitHub is a platform that hosts Git repositories online. It lets you share code, review changes, and automate testing. In this tutorial, you will learn to push code to GitHub, create pull requests, and set up basic CI/CD with GitHub Actions. ...

Your notes app works on both Android and iOS. The data layer syncs, the UI layer has navigation and editing, and the shared ViewModel handles all business logic. Now it is time to publish. In this tutorial, you will learn how to build a release APK for Android, archive an IPA for iOS, set up GitHub Actions CI/CD, and prepare for the Play Store and App Store. What We Are Covering Android release build — signing, APK, AAB iOS release build — Xcode archive, IPA export GitHub Actions CI/CD — automated builds on every push Signing basics — keystores and provisioning profiles Store submission overview — Play Store and App Store requirements Android: Building a Release APK Debug vs Release So far, we have been building debug APKs with ./gradlew :composeApp:assembleDebug. Debug builds are not optimized and include debugging tools. For publishing, you need a release build. ...
