Kubernetes

A fix I needed was already merged to cadvisor master, but stuck in no released tag for two months, quietly crash-looping kubelet on ZFS-graph-driver nodes. This is the story of moving it: the GitHub issues, the escalation that actually worked, the release that shipped ~90 minutes after a Slack ping, and the Kubernetes vendor-bump PR I opened that merged two hours later.

Discovered a gap in the Tailscale Kubernetes Operator through real-world GKE usage. Filed an issue and submitted a PR that was merged upstream. Tailscale has raised $160M in Series C funding -- yet this was missed by their team.

In February 2020 I reported a private image pull failure in the then-new GitLab Container Registry. Four years later the issue is still open, and engineers worldwide have used it as their reference.
