Flintlock is a Go service for creating and managing the lifecycle of microVMs on a host machine, backed by containerd and supporting Firecracker and Cloud Hypervisor VMMs. It exposes gRPC and HTTP APIs to create, start, stop, pause, and delete microVMs using OCI images for volumes, kernels, and initrds.

Use cases

create and manage microvms on a bare-metal host
run microvms as nodes in a virtualized kubernetes cluster
provision isolated lightweight vms for workloads
use oci container images to supply vm kernels and root filesystems
manage microvm lifecycle via grpc or http api
configure vm metadata with cloud-init or ignition

When to choose

you need lightweight, fast-booting VMs on bare-metal Linux hosts with KVM
you want to provision microVMs as Kubernetes nodes via Cluster API Provider Microvm
you prefer OCI images over large filesystem images for VM kernels and volumes
you want a programmatic gRPC/HTTP API for microVM lifecycle management

When to avoid

you need full VMs with broad OS or GPU support rather than lightweight microVMs
your host lacks KVM support or runs non-Linux operating systems
you only need container orchestration without VM isolation
you need CNI networking support today, as it is not yet fully available
