Open Source Weave Ignite - The GitOps VM
Talkat KubeCon + CloudNativeCon North America 2019 · on Wednesday, 2019-11-20· at 17:20· Room 6E - San Diego Convention Center, Upper Level·
summary
Weave Ignite packages Firecracker microVMs with OCI images + containerd + CNI so VMs look and behave like containers; it uses device‑mapper snapshots, an ignite spawn wrapper around Firecracker/KVM, and an ignite‑d reconciler to manage VMs from Git. Demo boots five different OCI images as VMs in about 2.8s on a nested Mac (Firecracker claims sub‑second and 4,000 VMs at scale). Ignite exposes Prometheus metrics, requires KVM and Linux kernel ≥4.14, and supports declarative GitOps control (one live demo showed a single VM failing to start).
