Kubernetes Port Forwarding Patterns 👇 You're inside a dev cluster, access to the network is restricted, and the service you just deployed is acting up. There’s no LoadBalancer, no ingress controller in place, and opening up a port is not an option because the network team is

My First Job: ₹ 80/day → Chittoor My First Corporate Job Switch: ₹ 1.8 LPA → Chennai My First Consultant Job Switch: ₹ 60 LPA → Singapore Job switches have never been easy for me. Especially if you come from a small town with broken English and no clue about corporate

When hiring, remember that not all DevOps Engineers are the same. Some are strong in CI/CD. Some are skilled in scripting. Some are specialists in security. Some are great with containers. Some are proficient in IaC tools. Some are experts in Kubernetes. Some are pros at

Why you should learn Linux before Kubernetes? > Kubernetes runs on Linux. If you don’t understand the OS, you’re debugging blind. > Pods fail because of Linux things: processes, signals, file descriptors, cgroups, namespaces. > “Container crashed” usually means a Linux

Me finally reading the Kubernetes runbooks after restarting the pod 17 times. I repeatedly see that everything depends on knowledge that was never written down. Lesson for new joiners: Don’t trust a running cluster. Trust documentation, git history, and intent. Before

DEVOPS CAREER STUCK is often just: - Cloud clicks without architecture thinking - Avoiding logs, metrics, and on-call - Weak Linux and networking basics - Kubernetes used, not understood - No production failures faced - Too many tools, zero depth - No proof of real impact Do

If I had to start learning Kubernetes again... ∟ 📂 Phase 1 (Weeks 1–4) Foundations ∟ 📂 Linux basics for Kubernetes processes, and networking ∟ 📂 Git and GitHub for storing manifests and workflows ∟ 📂 Networking basics IP, DNS, HTTP, and load balancers ∟ 📂 Phase 2

Cloud: Linux. Servers: Linux. Security: Linux. Containers: Linux. Networking: Linux. Automation: Linux. WTH, Linux runs everything. If you are into DevOps, Start with Linux first. Thank me later. 57K+ read my DevOps and Cloud newsletter: https://t.co/UStCmOZawZ What do we

Kubernetes is not an entry level job. It requires a deep understanding of container orchestration, architecture, complex system integrations, Linux, networking, security best practices, and the ability to troubleshoot and optimize distributed systems effectively. Expecting

Most Kubernetes errors aren’t Kubernetes errors. They’re Linux. Almost every pod, every container, every node… runs on Linux. Troubleshooting a pod stuck in CrashLoopBackOff? You’ll end up checking Linux logs. Struggling with persistent volumes? You’re debugging Linux file

Not a joke, many DevOps Engineers don’t fully understand the structure of a Helm chart or its components. Here, I’ve made this to help you better understand. 57K+ read my DevOps and Cloud newsletter: https://t.co/cwGmRpOs2e What do we cover: DevOps, Cloud, Kubernetes, IaC,

Here’s the part they don’t put in the DevOps job description: You inherit the problems nobody else wants. Your job isn’t just pipelines, clusters, or infra as code. Your job is fixing everything that touches production. - Flaky CI pipelines. - Untuned autoscaling. - Leaking

Client reported: “File uploads to S3 are failing.” API returned `500 Internal Server Error`. S3 bucket was healthy. IAM role had full access. No network issues seen. Request flow trace looked like: - Frontend → API Gateway: 45 ms - API Gateway → Lambda: 70 ms - Lambda → S3

Theory: Every part of modern DevOps is powered by Linux. Evidence: - CI pipelines use Linux runners. - Docker uses Linux namespaces and cgroups. - Even serverless often runs inside Linux microVMs. - Most AWS, GCP and Azure workloads run on Linux VMs. - Containers are Linux.

I call it 'DevOps Day 0' Roadmap 👇 Linux: File Systems, Package Management, Systemd, Permissions, Logs, Disk and Process Management Networking: TCP/IP, DNS, HTTP/S, VPN, Load Balancers, Firewalls, Network Protocols, Subnetting Database: SQL vs. NoSQL, ACID Properties,

Many think DevOps = tools + pipelines. Hook up Jenkins, Terraform, Kubernetes… done, right? That’s the easy part. The hard part? - Outages at 2 AM - Escalations nobody wants - Cloud costs burning money - Scaling that never behaves - Downtime you can’t predict The number of
