Git is an essential tool for developers, offering powerful source code management with its branching capabilities and distributed architecture. While the basics are sufficient to begin, true mastery involves advanced tactics. ℹ️These are the...

Your pull requests need a bodyguard. Enter GitHub Actions. Imagine having a security guard for your code. That's continuous integration (CI) for you. It checks your work before it's allowed to enter the main project. Think of it as a robust spell check, but for code. And GitHub Actions makes it happen once configured properly. When a developer submits a pull request: 1. GitHub Actions can automatically run a scripted set of routines to analyze your code. This usually includes running automated tests, checking coding conventions, and highlighting obvious security concerns. 2. If it passes (devs call this a "green build"), it's ready for review and can be brought into the main project. 3. If it fails (a "red build"), you can configure your code repository not to allow it into the main project. The developer who created the PR should address the failures. You can also configure CI routines to generate documentation and deploy a temporary demo of the new features the PR introduces. I've seen development teams get very creative with GitHub actions and other CI tools. Concerned about security? You can configure customized runners that execute the scripts in your existing cloud environment. Result? Higher quality software with fewer headaches. Note: the premise is simple, but not easy. Your dev team has to be committed to maintaining it, and ensuring it runs reliably. Ask your dev today: Are we using CI? #softwareengineering #engineeringleadership --- We help teams implement great practices like Continuous Integration.

Using a GitOps approach for managing deployments in your Kubernetes cluster can make it much simpler to handle deployments and also to track changes and manage drift. Clusters where people just deploy resources in an ad-hoc fashion tend to get messy quickly. GitOps is the approach where you use a source repo as the source of truth for your deployments and when you want to make changes you open a PR and when approved an operator in your cluster is listening and deploys the changes. With this approach you can also setup audit or gate controls which watch for changes outside the source repository. When these occur you can block them or revert them. Seeing practical examples of how to do things and the code involved always helps to reinforce what you read. In the article below Bora Köstem shows a good example of using ArgoCD, Helm, and Github Actions to deploy apps in a cluster. https://lnkd.in/euDCSJzf

Here’s a beautiful and simple explanation of GitHub Actions with icons to visualize the process easily: 🚀 GitHub Actions Workflow (Step-by-Step) 📝 Write Code You create or update your code in your local machine. 📤 Push to GitHub You upload (push) the code to your GitHub repository. ⚙️ GitHub Actions Starts Automatically GitHub detects the new code and starts running tasks automatically. 📂 Checkout Code GitHub downloads your project to a virtual machine for processing. 📦 Install Dependencies It installs the necessary tools and software needed for your project (e.g., npm, Python, etc.). ✅ Run Tests Tests are automatically run to check for errors and ensure everything is working fine. 🏗️ Build the Project The project is prepared and optimized for deployment (e.g., converting code, optimizing images). 🌍 Deploy to Server The built project is deployed to a live server, cloud, or hosting platform. 🔍 Monitor the Process You can check progress and errors in the "Actions" tab on GitHub. 📧 Get Notifications Receive alerts via email or Slack if something goes wrong. 🌟 Additional Features 🔒 Secure Secrets: Store sensitive information like passwords securely. ⏱️ Scheduled Runs: Automate tasks at specific times (e.g., daily backups). 🖱️ Manual Trigger: Deploy manually with a click if needed. GitHub Actions = Automation + Simplicity 🚀 It helps developers save time by automating testing, building, and deployment processes effortlessly. Would you like an infographic to visualize it even better? 😊 https://lnkd.in/gSsi3CJ2 #GitHubActions #DevOps #Automation #CICD #SoftwareDevelopment #CloudComputing #WebDevelopment #GitHub

#GitOps What is GitOps? GitOps is a modern approach to continuous delivery that uses Git as a single source of truth for declarative infrastructure and applications. It allows teams to manage and deploy applications using Git workflows. What is FluxCD? FluxCD is a set of continuous delivery tools for Kubernetes that automate the deployment of applications and infrastructure changes. It monitors your Git repository for changes and applies them to your Kubernetes cluster.
