Thanks for visiting, this organization contains all the projects related to Liquid Metal.

🎉 This project was originally developed by Weaveworks but is now owned & run by the community. If you are interested in helping out please reach out.

Liquid Metal is a set of open source projects for running lightweight virtual machines (microVMs) on your own hardware and managing them declaratively.

• Hard isolation, light footprint: every workload gets its own kernel and a real KVM boundary, without the overhead of a full VM
• Fast to boot, fast to throw away: microVMs start in close to container time
• More from your hardware: pack more workloads onto each bare-metal host, from datacenter servers to the edge
• Standard building blocks: Firecracker, Cloud Hypervisor, containerd, KVM and Kubernetes

Use it for:

• Kubernetes clusters with microVMs as nodes
• CI runners with a fresh microVM per job
• Ephemeral environments for previews, tests and development
• AI agent sandboxes to run untrusted code in

Hang on, what is this microVM thing you mention!?! A microVM is a very lightweight virtual machine that optimizes for speed and less resource consumption over supporting a wide array of devices. It gives you the isolation of a VM with close to the speed of a container.

Head over to liquidmetal.dev. The 30 minute tutorial builds a Liquid Metal platform on your own Linux machine.

• flintlock - an agent on each host machine that creates and manages microVMs via API calls. It does not know about Kubernetes, so you can use it to start a microVM for any task. It uses containerd so that container images can be the kernel and volumes for a microVM.
• Cluster API Provider Microvm (CAPMVM) - a Cluster API infrastructure provider. It creates microVMs on Flintlock hosts and bootstraps Kubernetes on them, so a microVM becomes a whole Kubernetes node.
• microvm-operator (experimental) - manage microVMs as Kubernetes resources: Microvm, MicrovmReplicaSet and MicrovmDeployment.
• brigade (experimental) - a distributed orchestrator that speaks the Flintlock API and schedules microVMs across a fleet of hosts.
• battery (experimental) - a warm pool manager that keeps pre-booted microVMs ready to claim instantly.
• guest-agent (experimental) - an agent inside the microVM that lets the host run commands and copy files over vsock.
• muster (pre-alpha) - runs each GitHub Actions job in a fresh microVM.
• image-builder - builds the container images that we use for microVM kernels and root volumes.

• hammertime and fl - CLIs for interacting with Flintlock.
• mikrolite - an experimental CLI for creating microVMs without Flintlock.
• flintlock-terraform and terraform-equinix-liquidmetal - Terraform support for Flintlock and for a Liquid Metal platform on Equinix Metal.
• EKS-Anywhere (EKS-A) (poc) - we have been working on adding CAPMVM as a provider to EKS-A.
