Paul Bezilla

Infrastructure and platform engineer. Kubernetes, observability, reliability, and cloud systems.

Recent projects

Five repositories: three stacked as application, platform, and cloud; capsize and switchyard standing separately, connected to nothing.

Three of these stack: otel-service-reference is the application, kubernetes-platform-reference is the platform it runs on, and terragrunt-reference-architecture is the cloud underneath.

capsize and switchyard are joined to nothing. capsize is a read-only Kubernetes CLI that scores cost waste against blast radius. switchyard is an inference gateway that routes across three simulated providers and fails over between them. Neither depends on any of the other three.

Field notes

Five checks that proved nothing

Building these systems exposed failures their checks missed. Five investigations into what went wrong, how I found it, and what changed.

mktemp -t means the opposite thing on macOS and Linux

-t takes a prefix on BSD and a template on GNU, so a line that works on macOS is impossible on a Linux runner. Reproducing it without a Linux box, and the form both accept.
