Hi, I'm Ayush 👋
Senior Site Reliability Engineer at Red Hat, keeping OpenShift and Kubernetes clusters alive at scale. Previously a Principal Engineer on the OpenShift Networking team — years inside OVN-Kubernetes, Service Mesh, DNS, and Ingress routing.
I write hands-on guides and make YouTube videos because a good explanation saves hours of debugging.
Who I Am
An engineer who went deep into Kubernetes networking and came out the other side building reliability into the platforms that run it.
🏢 Now — Senior SRE @ Red Hat
Platform reliability, incident response, scalability, and making sure production OpenShift clusters don't fall over under real load. Working across cloud providers, bare-metal environments, and hybrid deployments.🔙 Previously — Principal Engineer, OpenShift Networking
Years inside OVN-Kubernetes, Service Mesh 3, DNS Operator, and Ingress internals. Built detailed technical guides, debugged packet paths in production, and contributed to how OpenShift networking works today.📍 Red Hat — Building What Runs the Cloud
OpenShift runs critical workloads for thousands of enterprises. Working here means debugging real networking issues in production, understanding the full stack from kernel to API server, and building reliability tooling that entire teams depend on daily.
What I Work On
From cloud provisioning down to the packet level — and back up through pipelines and GitOps.
Projects & Published Guides
Hands-on repos and live guides built from real production experience — not toy examples.
OpenShift 4 DNS Architecture
Deep dive into CoreDNS, the DNS Operator, node resolvers, and production troubleshooting. Explains what actually happens when a pod resolves a service name.

OpenShift4-AWS-BareMetal-UPI
End-to-end procedure to deploy OCP 4 BareMetal UPI on AWS — every command, every config file, from infra to cluster.
must-gather-analysis
Shell scripts to verify OpenShift 4 cluster health from must-gather bundles. Spot issues fast without reading thousands of log lines manually.
Secured Gateway — Service Mesh
Deploy a secured gateway for applications using OpenShift Service Mesh — mTLS, certificate management, and route encryption end to end.
collect-tcpdump-ocp
DaemonSet to capture tcpdump on every interface across all cluster nodes simultaneously — the right tool for production network debugging.
openshift-mcp-server
MCP server exposing 216 tools, 7 resources & 10 SRE runbook prompts for OpenShift 4 cluster management via any MCP-compatible LLM across 20 operational domains.

Art of Exploitation
A YouTube channel about understanding systems at the packet and syscall level — not just how to use tools, but why they behave the way they do.
▶ Art of Exploitation
OpenShift internals, networking deep dives, live packet captures, and hands-on labs. No fluff — real cluster behavior explained from first principles. The kind of content I wish had existed when I was debugging at 2am.
▶ Watch on YouTube🎯 What You'll Find on the Channel
OVN-Kubernetes trace walkthroughs, OpenShift DNS deep dives, live packet captures, Service Mesh debugging, and the kind of root-cause analysis that doesn't fit in a Stack Overflow answer.✍ Blog — blackhatinside.com
Written guides on the same topics — when a concept needs more depth than a video can give. Think of it as the technical notes that go alongside the recordings.→ blackhatinside.com
