Kubernetes learning path from beginner to expert🚀🚀 Stage 1 -> Beginner lays the foundation with containers and Docker, so you understand why Kubernetes exists before learning what it does. Stage 2 -> Foundational is where you start deploying real apps, managing workloads, exposing them via services, and handling configuration. Stage 3 -> Intermediate introduces stateful workloads, networking depth, and the observability tooling used in every production environment. Stage 4 -> Advanced covers the security and automation concerns that matter in team and enterprise settings, RBAC, autoscaling, and GitOps. Stage 5 ->Expert takes you into the internals: building custom controllers, tuning cluster performance, and preparing for professional certifications (CKA/CKAD/CKS). A good practical target is to spend 2–4 weeks per stage. The official Kubernetes documentation is an excellent free resource throughout the journey.

@uday_devops @Hirpara_Daivik Let's connect

We can connect If you are in tech #letsconnect #tech

@therahul4402 Thanks bro

@uday_devops simple and clear words

Day 1 insight 💡 ☸  What is Kubernetes? ✦ Container orchestration platform- K8s is a container orchestration platform automating the deployment, scaling & management of containerized applications across machines. ✦ Self-healing - if a container crashes, K8s restarts it. No manual babysitting. ✦ Declarative model - you describe the desired state, K8s figures out how to get there. ✦ Open-source & CNCF-backed - originally from Google, now the industry standard.

@therahul4402 Yes, if you're the master, you can build a product/company 😏

@uday_devops We don’t have to master it we just need to understand how things work

Everyone wants a “Full-Stack Developer.” Very few understand what that actually means.📚📖 This image explains it better than any job description. 📕Full-stack ≠ Frontend + Backend 📘Full-stack = Frontend, Backend, Cloud, DevOps, Security, Networking, CI/CD, Containers, CDN, Backups It’s not about knowing everything. It’s about understanding how everything breaks together.

@anjalinirwal02 Cool 😎

@uday_devops job

Hii techies !! Comment your current level: → Just started → Learning basics → Building projects → Job-ready

@TechwithSaii Let’s go bro

Recovery started 😎

@youngbuffalo111 @X Hello

Hey @X algorithm, Looking to connect with people interested in: 🎨 Frontend 🧠 Backend 🤖 GenAI ✨ Full Stack ⚙️ DevOps ✅ DSA 🧠 AI/ML 🌐 Web3 📊 Data Science 💼 Freelancing 🐍 Python 🚀 Startups Let’s learn, grow, and build in public together 🔥💪

@__karnati Option C

Quick scenario: A new engineer joins your team, and they commit a .env file to the repo with DB credentials. The repo is private. The credentials still work. You catch it in code review. What do you do? A) Reject the PR, explain the issue, move on B) Reject + rotate the credentials immediately C) Reject + rotate + write a policy + add pre-commit hooks D) Reject + rotate + full audit of all recent commits And what would your answer be if the repo is public?

@nitin_coder No special reason I like .com feels unique

@uday_devops what is reason to choose this over others

Which domain ranks better? .io .ai .app .xyz .com

@vaneshmali Let’s grow together

Based on my observation, FOLLOWERS count matters for your reach on X. Let's connect 👋 I am here to learn something new from your posts and replies. I am here to share my learnings, knowledge and experience. Let's grow together 🌱

@YashHustle_22 Hello

Hey founders 👋 Let’s build a network of people working on: 🚀 Startups 🧠 AI 💻 Coding 📱 Apps ⚙️ Automation 🌐 Web products Reply with your project 👇

@Guptha933907 Good explanation 🙌

Answer: A common cause here is Ingress or load balancer misconfiguration. Even if pods and services are working internally, external traffic depends on: • ingress rules • load balancer routing • DNS configuration • service exposure type (ClusterIP / NodePort / LoadBalancer) Engineers usually check: • ingress configuration • external endpoints • DNS resolution If traffic never reaches the application, the issue is often at the entry point of the cluster, not inside it.

Daily DevOps Scenario #9 Your Kubernetes application works fine internally. Pods can communicate with each other. No errors in logs. CPU and memory are stable. But external users cannot access the service. Requests never reach the application. What would you investigate first? Answer will be shared in the thread.

@Ashh_404 Thank you ☺️

@uday_devops Informative

@ikishankewal Ok bro will come up with road map shortly

I want to learn CI/CD Starting with github actions today. Please suggest right order to do things #devops engineers

@nitin_coder Got it if restart works will be happy 😊

@uday_devops yeah sometimes running applications stops working even everything seems to be okay.

Interviewer: The Docker container is running, but the application is not reachable externally. What could be the reason?

Most people memorize the OSI model… but don’t actually understand it. Here’s the real breakdown: 1️⃣ Physical -> Cables, signals, hardware 2️⃣ Data Link -> MAC addresses & switching 3️⃣ Network -> IP addressing & routing (the internet’s GPS 🌍) 4️⃣ Transport -> TCP vs UDP (reliability vs speed ⚡) 5️⃣ Session -> Keeps conversations alive between systems 6️⃣ Presentation -> Encryption & formatting (security lives here 🔐) 7️⃣ Application -> What users interact with (HTTP, DNS, email)

@woody_hermit Correct, issue with the port mapping that’s needs to be addressed

@uday_devops If your logs are empty and your curl is timing out, you didn't deploy an app . you just successfully containerized a profound sense of disappointment.
