If you really want to learn something, reading isn't enough. You also need practice. This is why "Fundamentals of DevOps and Software Delivery" includes dozens of examples to try. In this video, Yevgeniy Brikman shows how "sandboxes" in the O'Reilly platform let you run the examples right in your browser, without having to install anything!

Do you know 4 core principles of GitOps? The methodology that's revolutionizing how teams manage infrastructure and applications. 1️⃣ Declarative: Define your system's desired state using code (e.g., Kubernetes YAML). The system figures out the rest. 2️⃣ Versioned & Immutable: Git is the single source of truth. Every change is a versioned, auditable commit, making rollbacks simple and reliable. 3️⃣ Pulled Automatically: In-cluster agents automatically pull and apply changes from the Git repository, minimizing manual intervention and boosting security. 4️⃣ Continuously Reconciled: The system constantly verifies that the live state matches the desired state in Git, automatically correcting any configuration drift. Using these principles, teams can achieve faster, safer, and more consistent deployments. What has been your experience with adopting GitOps? #GitOps #DevOps #ContinuousDelivery #Kubernetes #InfrastructureAsCode #CloudNative

Tired of wondering what actually gets deployed in software development? 💡 It's the Artifacts! We break down the critical role of these essential, immutable, and versioned outputs that power Continuous Delivery (CI/CD) from code to production. Artifacts are the unsung heroes of modern deployment. Learn why they are so fundamental to DevOps in this short video! 👇 ➡️ Watch now: https://lnkd.in/gyDZ2NbQ #DevOps #CI_CD #Artifacts #SoftwareEngineering #ContinuousDelivery

🚀 Day 35 - KodeKloud 100 Days Challenge 🚀 Today’s milestone: Successfully installed Docker CE and Docker Compose on CentOS! 🐳 🔧 Why Docker? Docker is the essential containerization platform that empowers developers and DevOps engineers to build, ship, and run applications consistently across environments. 🛠️ Installation Highlights: 1)Remove old versions sudo yum remove -y docker docker-client docker-common docker-latest 2) Add Docker repo sudo yum install -y yum-utils sudo yum-config-manager --add-repo https://lnkd.in/gdnCQ3U4 3) Install Docker CE and Compose plugin sudo yum install -y docker-ce docker-ce-cli containerd.io docker-compose-plugin 4)Start and enable the Docker service sudo systemctl start docker sudo systemctl enable docker 5) Verify installation docker --version docker compose version 🌟 What this means: With Docker and Docker Compose installed, managing multi-container applications becomes effortless, boosting productivity and deployment agility. 🎯 Let's continue to push the boundaries of automation and container orchestration! 💪🔥 #Docker #DockerCompose #DevOps #KodeKloud #100DaysOfCode #Containers #CentOS #Automation #CloudNative

🚀 Great software starts long before the first line of code. 🔍 See the whole picture: understand processes, domains, and future scale. 🏗️ Design the architecture: keep it lean, but solid. ⚙️ Implement the essentials: no unnecessary setup. 🔄 Integrate Git + CI/CD: ensure smooth collaboration and reliable delivery. Because without a strong foundation, scaling becomes chaos. 👉 How do you make sure your software stays simple and scalable? #SoftwareArchitecture #ScalableDesign #DevOps #CICD #TechLeadership #Innovation #Arero7

⚓ How the Game changed ? Lest's see 🚀 Traditional pipelines deploy software. But #Kubernetes delivers resilience, speed, and trust. 🔹 Consistent Builds Every environment runs exactly the same — no “works on my machine.” 🔹 Zero-Downtime Deployments Blue-Green, Canary, Progressive — Kubernetes automates them all. 🔹 Self-Healing Infrastructure Pods crash? Kubernetes restarts them. Automatically. 🔹 Smarter Pipelines Tools like ArgoCD & Jenkins integrate directly with the Kubernetes API — your delivery becomes declarative and automated. 💡 With Kubernetes, CI/CD isn’t just about delivery. It’s about continuous confidence. ⭕️ Faster feedback loops ⭕️Safer releases ⭕️Happier teams 🌍 In 2025, cloud-native CI/CD = Kubernetes. 💚 I ❤️ DevOps | 💙 I 💚 Kubernetes #DevOps #CICD #GitOps #CloudNative #Automation #ContinuousDelivery #ContinuousInnovation

Infrastructure as Code: The DevOps Superpower Before IaC, provisioning infrastructure meant manual steps, endless tickets, and “it works on my machine” headaches. Now, with tools like Terraform, CloudFormation, and Ansible, we can: ✅ Define infrastructure in code → version control with Git ✅ Automate deployments → consistent environments ✅ Scale and rebuild infrastructure in minutes, not days ✅ Enable true DevOps collaboration between devs & ops 👉 IaC is more than automation. It’s about treating infrastructure like software—tested, reviewed, and reproducible. 💡 My rule: If it isn’t in code, it doesn’t exist. Do you already use IaC in your projects? If yes, which tool do you prefer—Terraform, Ansible, or CloudFormation? #DevOps #InfrastructureAsCode #Terraform #Automation #CloudEngineering

👉 Ever wondered how to deploy new code safely and efficiently? It all comes down to choosing the right Kubernetes deployment strategy! This visual breakdown covers essential approaches like: Canary: Gradually testing updates with real users. Blue-Green: Instant rollbacks with zero downtime. A/B Testing: Experimenting with features and gathering user feedback. Rolling Update: Continuous updates without service interruption. Recreate: Simple but with downtime. Shadow: Testing under real workloads without user impact. Each comes with its own trade-offs, ensuring you can pick the best fit for your application's needs. Which strategy is your go-to? Share your experiences below! #Kubernetes #K8s #DevOps #Deployment #CloudComputing #Containerization #SoftwareEngineering #TechInsights #SystemDesign #ITOperations #ReleaseManagement #CanaryDeployment #BlueGreenDeployment #RollingUpdate #ABTesting

I’ve spent the last few days getting hands-on with DevOps concepts, testing how Docker, Kubernetes, and automation tools work together in real setups. I built a collection of small, practical examples and organized them in this repository. It contains a set of examples where I applied different DevOps concepts: * Containerization using Docker and Docker Compose. * Load balancing & reverse proxy with Nginx image. * Orchestration through Docker Swarm and Kubernetes. * Configuration & secrets management using ConfigMaps and Secrets. * Persistent storage with Kubernetes persistent volumes and claims components. * Full app deployment: a simple CRUD app running on Kubernetes, with: - Deployments and Services for frontend, backend, and database. - Secrets for sensitive environment variables. - ConfigMaps for shared app configuration. - Persistent Volumes & Claims for Postgres database storage. - Ingress routing through Nginx for local domain access (like notes.local). If you’re also exploring DevOps or Containerization tools, maybe this repo can help you get some insights. And if you’ve been working with Docker or Kubernetes for a while, I’d really appreciate your feedback or suggestions on how to improve it. Also, feel free to fork, improve, or suggest new examples! #DevOps #Docker #Kubernetes #Containerization #LearningByDoing #OpenSource #Automation https://bit.ly/4o4kNAK
