Technical deep-dives from building the minicloud platform — GitOps, Kubernetes, AI, and bare-metal engineering.
Kubernetes does not automatically restart pods when a mounted ConfigMap changes — especially when using subPath mounts. We added Stakater Reloader to eliminate manual kubectl rollout restart calls across Homer, LiteLLM, SearXNG, and Backstage. Here's the problem, the fix, and a bonus ArgoCD OOMKill investigation we uncovered along the way.
