What is flintlock?​

Flintlock is a service for creating and managing the lifecycle of microVMs on a host machine. Initially we will be supporting Firecracker, with an aim to default to Cloud Hypervisor in the future.

The primary use case for flintlock is to create microVMs on a bare-metal host where the microVMs will be used as nodes in a virtualized Kubernetes cluster. It is an essential part of Liquid Metal and will ultimately be driven by Cluster API Provider Microvm.

Features​

Using API requests (via gRPC or HTTP):

  • Create, update, delete microVMs using Firecracker
  • Manage the lifecycle of microVMs (i.e. start, stop, pause)
  • Configure microVM metadata via cloud-init, ignition etc
  • Use OCI images for microVM volumes, kernel and initrd
  • (coming soon) Use CNI to configure the network for the microVMs
