Transmissions
The pipeline is proven. The dashboard still has blank panels.
100 requests confirmed the API is stable. Prometheus Explore proved cAdvisor is scraping. The CPU Usage panel was fixed by removing a cluster label filter that Minikube never populates. The top stat cards and memory graphs are still blank — same fix, not yet applied.
Continue reading →Restructured the codebase, built three new verticals, and closed every security vulnerability.
A Python script migrated 25 files into a feature-based layout. Travel Tickets, Courier & Moving, and Kampala Real Estate Broker were built from scratch. The monorepo came out of a security audit clean.
Continue reading →The cluster ran out of room. Two pods broke. Scaling down fixed both.
A Helm upgrade to revision 5 triggered new monitoring pods on a node already out of CPU and memory. Grafana froze during a Docker Hub handshake. kube-state-metrics crashed 11 times. Scaling the API down to 2 replicas gave the node enough room. Both pods recovered.
Continue reading →The quota I set in 012 blocked the rollout I ran today.
Fixed the cAdvisor TLS gap, bumped CPU limits for the 97-second startup problem, and hit three consecutive Helm errors before the upgrade landed. Then the namespace quota from 012 blocked every new pod. Deleted the quota. The rollout completed in 23 seconds. The pipeline is verified.
Continue reading →One codebase, three shop types, and a Zustand subscription loop crash.
Hubal POS split into three adaptive variants — pharmacy, cosmetics, supermarket — from a single codebase. A Zustand subscription pattern crashed the app at the end of a long session.
Continue reading →The quota landed. The utilisation panels still say nothing.
The slow pod from 011 came back late again — 97 seconds between gunicorn and application startup. Resource limits hit the namespace. Grafana's utilisation panels are still blank, and now I know exactly why.
Continue reading →ResNet-50 saw the load. The dashboards learned to watch.
100 waves of traffic through all four pods. Grafana panels built from scratch. The request rate and inference latency are now visible in real time.
Continue reading →The 404 was a ghost. The image was stale.
Prometheus scraped /metrics and got 404. The route existed in main.py on disk. It did not exist inside the running container. The pods were serving an image that predated all the monitoring code.
Continue reading →Prometheus is in. The build keeps dying.
Wiring Prometheus into the cluster hit three walls: a broken package manager, a missing metrics route, and a Docker build that hangs for over an hour inside Minikube every time pip touches the network.
Continue reading →ResNet-50 takes 60 seconds to load. The cluster didn't know that.
A slow PyTorch startup window caused 502s on freshly rolled pods. I added resource ceilings, a dual-metric HPA, and startup probes to close the gap.
