🚀 From Zero to Full-Stack DevOps on Microsoft Azure! I just completed a series of hands-on DevOps assignments, and I want to share what I learned along the way Self-Hosted Agents Instead of using Microsoft's hosted agents with limited free minutes, I provisioned my own Ubuntu 22.04 VM on Azure, registered it to Azure DevOps using a Personal Access Token, and installed it as a system service. This gave me unlimited free pipeline minutes and full control over my build environment! CI/CD Pipelines I built automated pipelines that triggered on every commit to main: ✅ Deployed a static HTML website via SSH ✅ Built and deployed a React app through a 4-stage pipeline (Build → Test → Publish → Deploy) ✅ Deployed the EpicBook full-stack bookstore with Node.js and MySQL Nginx as a Reverse Proxy Nginx sits in front of the Node.js app and forwards port 80 traffic to port 8080. This is a standard production pattern used by companies worldwide! Infrastructure as Code with Terraform. Using two repositories, one for Terraform infrastructure code and one for application code, keeps concerns separated and mirrors real enterprise DevOps workflows. Key Lessons: File permissions matter in pipelines Every error is a learning opportunity Real DevOps is about troubleshooting, not just deploying! This journey was challenging but incredibly rewarding! If you are learning DevOps, my advice is simple: get your hands dirty! What DevOps tools are you currently learning?

Day 31 of my DevOps journey — and today was all about Docker 🐳 Honestly? Docker felt intimidating at first. But today it finally *clicked*. Here's everything I built and learned today 👇 🔹 Understood CMD vs ENTRYPOINT (the coffee machine analogy changed everything ) 🔹 Debugged a real COPY error in Dockerfile and fixed it 🔹 Hunted down a hidden .dockerignore file (yes, dot files are invisible by default 👻) 🔹 Deployed an Nginx container on AWS EC2 and hit it live on the browser 🔹 Built a fashion app frontend and served it via Docker + Nginx 🔹 Mastered build optimization — layer order = faster builds The biggest lesson today? 📌 ENTRYPOINT is locked 🔒 — it always runs 📌 CMD is flexible 🔓 — it can be overridden 📌 Layer order in Dockerfile matters MORE than you think — put frequently changing lines LAST to keep your cache intact Every error today was a lesson. Every fix was a win. 🔗 Full code & Dockerfile on my GitHub → https://lnkd.in/gY4-7req If you're also on a DevOps / Cloud learning journey, let's connect and grow together 🤝 #Docker #DevOps #AWS #EC2 #Nginx #Linux #90DaysOfDevOps #CloudComputing #LearningInPublic #DevOpsJourney #TrainWithShubham

I’ve been learning Cloud and DevOps by building a small project from scratch and taking it all the way to production. So far, I’ve built and deployed a simple application: • Python (Flask) backend • Redis database to store a visit counter • Basic frontend served from the backend On the infrastructure side: • Containerized services using Docker 🐳 • Pushed the backend image to Docker Hub 📦 • Deployed on AWS (EC2 – Amazon Linux) ☁️ • Provisioned infrastructure using Terraform ⚙️ The application runs in a containerized setup, with services communicating between containers and Redis used for persistence. Now I’m focusing on improving the setup: • Automating deployment (CI/CD) 🔄 • Refining infrastructure configuration • Making the system more robust and reproducible The goal is to understand the full path from local development to a working cloud deployment using real-world tools. Still a lot to learn, but this project has helped me connect many concepts that were previously separate. 🧠 #Cloud #DevOps #AWS #Docker #Terraform

Sharing this an amazing DevOps roadmap and It very useful! 🚀 Reposting this DevOps roadmap — super clear and helpful 👏 Found this DevOps 90-day plan really informative. Sharing!

🚀 DevOps Roadmap: From Linux to CI/CD Feeling overwhelmed by the endless tools in the DevOps world? You’re not alone. The ecosystem is huge, but it becomes much simpler when you break it down into layers. Whether you’re just starting out or already experienced, mastering these 8 core pillars is key to building scalable and reliable systems: 1️⃣ Linux Basics – Everything starts here. Strong command-line skills and Bash scripting are essential. 2️⃣ Networking – Know how systems communicate (HTTP/S, SSH, TLS). 3️⃣ Cloud Platforms – Get comfortable with AWS, Azure, or GCP. 4️⃣ Security – Think “shift left”—focus on security from day one. 5️⃣ Containers & Orchestration – Docker and Kubernetes power modern apps. 6️⃣ Infrastructure as Code (IaC) – Manage infra like code using tools like Terraform and Ansible. 7️⃣ Observability – Monitoring and logging help you understand and fix systems faster. 8️⃣ CI/CD – Automate everything from code to production. 💡 Key takeaway: Don’t try to learn everything at once. Focus on one tool per layer, understand the concept deeply, and build step by step. #DevOps #CloudComputing #SoftwareEngineering #TechCareer #Kubernetes #AWS #ContinuousLearning #Linux #SRE #CICD
