Mastering DevOps with Linux and Kubernetes Commands

After years of working with DevOps tools, I realized that we use a core set of commands almost every single day, yet they’re rarely documented in one place. So I’ve started curating everything i.e Git, Terraform, Kubernetes, Linux and more into simple, practical cheat sheets on Hashnode.....with many more to come 🙌 .

🚀 Kubernetes Monitoring with CLI – Back to the Basics Today I spent time working directly from the command line to monitor and manage my Kubernetes workloads — and it reminded me of something important: 👉 If you want to master Kubernetes, you must be comfortable with Linux and the CLI. Here are a few commands I used while managing deployments: -kubectl rollout undo deployment web-app → Roll back to a previous version -kubectl rollout history deployment web-app → View deployment revisions -kubectl delete deployment web-app → Clean up resources 💡 These commands are not just for exams like CKAD/KCNA — they are real-world DevOps skills used in production environments. Working from the CLI gives you: ✔️ Better control over your cluster ✔️ Faster troubleshooting ✔️ Deeper understanding of how Kubernetes actually works 🔥 My advice: -Don’t rely only on dashboards and GUIs. Learn the terminal. Learn Linux. That’s where real power is. -I’m continuing to build and document real-world Kubernetes projects — next step: scaling microservices and adding ingress.

Most people don’t struggle with DevOps… they struggle with skipping the basics. Jumping tools → feels productive Starting new courses → feels like progress Blaming complexity → feels justified 🔍 But real growth? It’s quieter. It’s going back to fundamentals: • Understanding Linux • Getting networking right • Actually reading errors • Seeing the bigger architecture That’s what separates “trying DevOps” from getting it. Fundamentals aren’t optional. They’re everything 🧠 Follow for more and let's grow together Muhammad Hashim ________

DevOps is not about tools — it’s about how everything connects ⚙️💻 When Linux, Git, Docker, Kubernetes, Terraform, Ansible, and AWS work together, you don’t just manage code — you build scalable, automated, and reliable systems 🚀 Understanding the flow is what separates execution from just knowledge 🔥 #DevOps #CloudComputing #Automation #AWS #Docker #Kubernetes #Terraform #Ansible #Git #Linux #CI_CD #DevOpsEngineer #Infrastructure #TechGrowth #Engineering #ITSkills #ScalableSystems #ModernTech #LearnDevOps #CloudEngineer

Something I learned the hard way; Many people think DevOps starts with tools like Docker, Jenkins, or Kubernetes. It doesn’t. It starts with understanding the process those tools automate. If you can’t trace a deployment manually, read logs, debug an API issue, or identify where a release failed, a tool may help you move faster, but it won’t help you think better. Tools scale good processes. They don’t replace understanding. That shift changed how I look at DevOps. #DevOps #Linux #CI_CD #SoftwareEngineering #TechLearning #CloudComputing

☝️Headline: 🚀 21 Days Down, 79 to Go! #100DaysOfDevOps Challenge Body: Today marked a major shift in my DevOps journey—Git! 🛤️ As part of the KodeKloud 100 Days of DevOps challenge, Day 21 was all about setting up a Bare Git Repository on a storage server. Key Takeaways: ✅ SSH into storage servers to set up version control infrastructure. ✅ Understanding that --bare repositories are the backbone of central, collaborative workflows. ✅ Configuring remote repositories for team projects. It's amazing how much I've learned about Git and Linux in just three weeks. #DevOps #Git #KodeKloud #LearningJourney #VersionControl #100DaysOfDevOps

We literally used sudo in the last lecture… And no one asked why. That’s the problem. Most people learning Linux for DevOps don’t actually learn things… They just follow along. Run this command. Copy that step. It works - so they move on. Until one day… Production says: Permission denied. And suddenly: – Commands stop working – Logs are inaccessible – Panic starts Because now it’s not about what to type It’s about who you are in the system User? sudo user? root? That difference decides everything. I’ve seen engineers who know Docker, Kubernetes, CI/CD… But still get stuck on something as basic as privileges. Not because it’s hard - But because no one explained it properly. So instead of just using sudo again… We stopped. And broke it down: – What actually happens when you run sudo – Why switching to root is risky – When to use su vs sudo in real systems Because DevOps is not about running commands. It’s about understanding control. And in Linux… control starts with privileges. If you’ve ever used sudo without thinking… You should probably watch this one.

I’ve just uploaded a new video for beginners who want to learn Git in a simple and practical way. In this lesson, I show how to view commit history, check changes before committing, and undo common mistakes in Git. The video covers: ✅ git log ✅ git diff ✅ how to read commit history ✅ how to check file changes ✅ git restore ✅ how to undo uncommitted changes ✅ how to improve the last commit ✅ good and bad commit message examples This is Lesson 3 of my Git for Beginners series. If you are learning Git, DevOps, or software development basics, this lesson can help you build a stronger foundation. https://lnkd.in/eCVX9Cn6 #Git #DevOps #Linux

🚀 DevOps in action — mastering the fundamentals to go further In today’s fast-evolving IT landscape, mastering DevOps tools is no longer optional — it’s essential. I’ve recently consolidated a comprehensive cheat sheet of essential commands, covering: 🔹 Linux (from basic to advanced) 🔹 Git & version control 🔹 Docker & containerization 🔹 Kubernetes & orchestration 🔹 Helm & deployment management 🔹 Terraform & Infrastructure as Code 💡 The goal? Increase efficiency, automate intelligently, and improve infrastructure reliability. 👉 Behind every command lies a clear purpose: simplify, secure, and scale systems. #DevOps #Linux #Docker #Kubernetes #Terraform #Git #Automation #Cloud #SysAdmin
