Understand Multi-Stage Docker Builds for Interview. 🟢What is a Multi-Stage Build ? - A way to use multiple FROM instructions in a Docker file to create clean, small, production-ready images. - It helps separate build and runtime environments. 🔵Why Use Multi-Stage Builds ? - Avoid shipping build tools and source code into production. - Reduce image size drastically. - Improve security and performance. ➡️Below is the Example of a Node.js Multi-Stage Dockerfile. 🟤Explanation: First stage: Installs dependencies, builds the app. Second stage: Uses a lightweight NGINX image to serve built static files. Only the final built output is included in the final image. ⚪️Benefits: - Smaller final image. - Separation of concerns (build vs runtime). - Supports any language or framework.

Friday afternoon and the manager starts looking for you.

DevOps during RCA meeting, describing what went wrong.

@clovistb Ohhh noo

@devops_nk He will send you an email and cc the HR.

@AIContextWindow I hope no 🙂‍↔️

@devops_nk Are you gonna fall on the manager? 😁

@asynctrix I am on weekend mode now

@devops_nk 😂

@shakquraa 😄😄😄

@devops_nk 😂 lol

@Just_sharon7 Yes

@devops_nk Everyone explains while logs tell truth

@TheCesarCross Very True

@devops_nk Logs tell truth, RCA remains a team effort

@vaneshmali Good to know sir, Yes I do have side income and it's greater than my salary.

Most of you know that I own the TechnoVans(.com) platform. Income from this platform in 2025 is Rs. 19845. Good side income 😍 Do you have a side income?

Loyalty is not meant for corporate. Keep switching companies. Most companies don’t really care about you. At the end of the day, you have to take care of yourself and your career.

This question was asked in my last DevOps interview. What is Static Pods in Kubernetes ? A Static Pod is created and managed directly by the kubelet on a node, not through the Kubernetes API server. It works by placing a pod manifest file on the node, usually in: /etc/kubernetes/manifests The kubelet continuously monitors this folder and automatically creates or restarts the pod if needed. Where are Static Pods used ? - Mostly for control plane components in self-managed clusters (like kubeadm), because these components must run even if the API server is not fully available. Examples: • kube-apiserver • kube-scheduler • kube-controller-manager • etcd Important: kubelet starts them directly on the node, ensuring the control plane can bootstrap itself. Where Static Pods are NOT used ? In managed Kubernetes services like: • Amazon EKS • Google GKE • Azure AKS The control plane is managed by the cloud provider, so these components are not visible as static pods. On worker nodes you typically only see components like: • kube-proxy • CoreDNS • CNI plugins Save it for your next interview and follow for more.

Me after working 3 years in MNC.

Taking a short break 🌴 For the past few months, I’ve been pushing myself hard constantly building, learning, and growing. And honestly I’ve achieved a lot too. Now it’s time to pause for a bit. Going on a 2–3 day vacation with a friend ✌️ Don’t worry content is already scheduled for your learning & entertainment. Will be back soon. Thanks for all the insane love & support ❤️

Ideas deserve more than one frame. Now they get an entire world. And infinite shots.

@devopscdt It's Kokan it is in Maharashtra it's very beautiful

@devops_nk Enjoy.. which place is this?

@AiCamila_ Thanks Camila 🙌

@devops_nk Well deserved 🔥 go recharge and come back stronger 💯💻
