summary

Virtual Kubelet connects Kubernetes to Netflix Titus by treating pods as opaque objects and embedding legacy container metadata as a base64-encoded pod annotation, letting the existing Titus executor run unchanged under systemd-managed Titus executor to handle cgroups and Docker. An 11-person team deploys a VK instance per host, runs Mesos and Kubernetes side‑by‑side with Titus Federation, and migrates users in flight with comparable container‑starts‑per‑second rates. Key pain: reverse‑engineering kubelet state transitions and controller behavior; future plans include Firecracker/Gvisor executors.
