#Kubernetes Journey – Day 8: Volumes & Persistent Volumes In Kubernetes, containers are ephemeral – once a Pod is deleted or restarted, its data is lost. That’s where Volumes & Persistent Volumes (PV) come into play. 🔹 Volume – Provides storage to a Pod, ensuring data is available during container restarts inside the same Pod. 🔹 Persistent Volume (PV) – A cluster-wide storage resource that exists independently of Pods. 🔹 Persistent Volume Claim (PVC) – A request made by a Pod to use storage from a PV. ✅ Key Takeaways: Volumes solve the ephemeral nature of containers. PVs abstract the underlying storage (NFS, AWS EBS, GCP PD, Azure Disk, etc.). PVCs let developers request storage without worrying about backend implementation. StorageClasses automate dynamic provisioning of volumes. 💡 Real-World Example: Imagine running a database Pod (MySQL/Postgres) – you cannot afford to lose data every time the Pod restarts. By using PVCs with PVs, you ensure your data persists reliably. #Interview Question for You: Q.What is the difference between Volume, PV, and PVC in Kubernetes? #Kubernetes #DevOps #CloudComputing #Containers #LearningJourney Pod → PVC → PV → Storage

It’s a common pattern. A few capable SREs or infra engineers start building out pipelines, provisioning scripts, and internal tooling. Before long, someone starts calling it a “platform.”  But when you take off the label, you find a handful of overburdened experts duct-taping critical workflows together with no shared roadmap, no service boundaries, and no time to think beyond immediate delivery. What makes a true platform team isn’t tooling expertise. It’s alignment on purpose and practice. Does your team have a clear definition of what internal DevEx actually means in your context? Do you have a shared mental model around service ownership, product thinking, and feedback loops? Do you know where the platform ends and app teams begin or are you stuck in a constant tug-of-war over support tickets and blurry responsibilities? Training helps you build that model. Not in abstract, but rooted in the real decisions your team makes every week: how to structure a golden path, how to define API contracts between dev and platform teams, how to version and evolve the platform like a product, not a static system. We bring your team through those frameworks together, so everyone in infra, dev, security, even management can speak the same language. And we don’t stop there. Through ongoing advisory, we stay close to your real problems. We pair with your tech leads. We evaluate decisions not just for technical soundness, but for cultural alignment and long-term sustainability. Because what you need isn’t just a more skilled team. You need a cohesive one, operating with clarity and purpose. That’s how platform transformations stick. If you’re curious about how that might look inside your org, explore the details here👉https://lnkd.in/dfTaZyAV

Normal Pod vs Secured Pod – Why Security Context Matters in Kubernetes In today’s cloud-native world, containers and Kubernetes have become the backbone of modern applications. But with great agility comes an equally important responsibility: security. As solution architects, we must not only design for scalability and performance but also embed security as a first-class citizen in our architecture. One of the most overlooked areas in Kubernetes is the difference between a Normal Pod and a Secured Pod. At first glance, both seem identical—they run workloads, expose services, and scale as needed. But under the hood, the security posture can make all the difference between a resilient system and an open door for attackers. 🔹 Normal Pod A normal pod often runs with default settings. This usually means the container may run as root, the filesystem is writable, Linux capabilities are not restricted, and host-level access is possible. While this works for development speed, it leaves the environment vulnerable. If compromised, such a pod could allow privilege escalation, lateral movement across the cluster, or even host takeovers. 🔹 Secured Pod A secured pod, on the other hand, is designed with defense-in-depth principles. It enforces a SecurityContext and Pod Security Standards such as: Running as a non-root user Using a read-only filesystem Dropping all unnecessary Linux capabilities Applying seccomp/AppArmor profiles to restrict system calls Enforcing resource limits to prevent denial-of-service attacks By shifting left and securing pods at the design stage, we significantly reduce the attack surface. This also aligns with compliance frameworks like CIS Benchmarks, PCI DSS, and zero-trust models. 🔑 Why does this matter at an architectural level? Because Kubernetes security is not just a DevOps problem—it’s an enterprise resilience challenge. When you standardize secured pods, you embed trust into your CI/CD pipelines, accelerate audits, and prevent costly breaches. More importantly, you enable teams to innovate faster without the constant fear of vulnerabilities. ✅ Takeaway: A normal pod may be enough to run an app, but a secured pod ensures that the app runs safely, responsibly, and compliantly. As architects and technology leaders, we must advocate for secure defaults and foster a culture where security is seen not as a blocker, but as an enabler of sustainable innovation.

𝐊𝐮𝐛𝐞𝐫𝐧𝐞𝐭𝐞𝐬 𝐎𝐛𝐣𝐞𝐜𝐭𝐬 𝐄𝐱𝐩𝐥𝐚𝐢𝐧𝐞𝐝 𝐈𝐧 𝟏𝟓 𝐒𝐢𝐦𝐩𝐥𝐞 𝐁𝐥𝐨𝐜𝐤𝐬 🧱 Kubernetes is built from small parts that work together. Each object has a job. Learn what they do — and why they matter. 1. Pod – The smallest unit. Runs your app containers. 2. Deployment – Keeps your pods running and updates them safely. 3. ReplicaSet – Makes sure the right number of pods are always running. 4. StatefulSet – Like Deployment, but for apps that need stable storage or names. 5. Job – Runs a task once, then stops. Great for batch work. 6. DaemonSet – Runs one pod on every node. Good for logging or monitoring. 7. Service – Gives your pods a stable way to talk to each other. 8. Ingress – Lets traffic from outside reach your app. 9. Network Policies – Control who can talk to whom inside the cluster. 10. Volume – Temporary storage for pods. 11. Persistent Volume – Long-term storage that survives pod restarts. 12. Secret – Stores sensitive data like passwords. 13. Namespace – Splits the cluster into groups. Helps with isolation. 14. Service Account – Gives pods an identity to access the API. 15. Roles – Controls what users or pods are allowed to do. Learn these, and you’ll understand how Kubernetes really works. #devops #interviewtips #kubernetes #cloudcomputing
