awesome-baremetal

Bare-metal is awesome. Let's share our favourite tools.

Rules

• Ordered alphabetically (eventually consistent)
• Recent development or release (within the last 6 months) - or deemed relevant by curator
• No defunct or abandoned projects
• Must show signs of traction or corporate use
• No "my scripts for my homelab that only I use" submissions.
• This list is curated and not a museum, so the project should be active and relevant
• Format: link to GitHub or website - "quote from GitHub repo or website"

🏆 Commercial products will require a sponsorship and are added with (sponsored) in brackets in the relevant category.

Sponsorship tiers:

• "Top of rack" - featured at the top of this repository
• "1U" - a link in the relevant section plus the text "(sponsored)"

Curator: Alex Ellis - founder of OpenFaaS, actuated.dev & Inlets.

Networking for bare-metal cloud

Tools often used with bare-metal tooling:

• dnsmasq - "Dnsmasq provides network infrastructure for small networks: DNS, DHCP, router advertisement and network boot."
• HAProxy - "The Reliable, High Performance TCP/HTTP Load Balancer" - often used in place of hardware LB.
• inlets - "A Cloud Native Tunnel for L4 TCP and L7 HTTPS" (sponsored)
• inlets-operator - "Public IPs for your private Kubernetes Services using inlets"
• kube-vip - "Kubernetes Control Plane Virtual IP and Load-Balancer"

• Varnish-Cache Varnish Cache, the high-performance HTTP accelerator

Bare-metal cloud

Rent bare-metal from a cloud vendor on an hourly, monthly, or longer term commitment.

For a more comprehensive list see the actuated docs: Provision a Server. Actuated runs CI in ephemeral microVMs using Firecracker so requires bare-metal or nested virtualisation.

x86_64 and / or arm64:

• AlibabaCloud bare metal - x86_64 & arm64
• AWS Bare Metal - x86_64 & arm64
• Equinix Metal bare-metal infrastructure - x86_64 & arm64 (End of Life)
• Hetzner - x86_64 and arm64 (Best value for money, Europe region only)

The Raspberry Pi 4B and 5 provide arm64 support with several operating systems like Ubuntu LTS being available. An NVMe can be plugged in over USB-C or PCIe, see also: Upgrade your Raspberry Pi 4 with a NVMe boot drive and Booting the Raspberry Pi 5 from NVMe

The Mac Mini M1 and Mac Mini M2 can be installed with Asahi Linux, which then provides one of the fastest CPU/storage options for a self-hosted local Arm64 Linux host.

x86_x64 only:

• cherryservers.com - x86_64 only
• FastHosts bare metal - x86_x64
• hivelocity - x86_64 only
• IBM Cloud - x86_64 only

Open Source Virtualization

Orchestration of Virtual Machines (VMs) using KVM.

• Firecracker
• Cloud Hypervisor
• QEMU - QEMU is the traditional hypervisor, which now contains a "microvm" profile
• oVirt - "oVirt is an open-source distributed virtualization solution, designed to manage your entire enterprise infrastructure. oVirt uses the trusted KVM hypervisor and is built upon several other community projects, including libvirt, Gluster, PatternFly, and Ansible."
• Ganeti - "Open source hyperconverged VM platform that scales from several to thousands of bare metal servers. Originally written for internal use at Google."
• Proxmox VE - "Proxmox VE is a complete open-source platform for all-inclusive enterprise virtualization that tightly integrates KVM hypervisor and LXC containers, software-defined storage and networking functionality on a single platform"
• actuated.dev - blazing fast CI for GitHub Actions using Firecracker (sponsored)

Storage for bare-metal

• OpenEBS - "Open Source Container Attached Storage, simplifies running Stateful Applications on Kubernetes.
• Rook - "Open-Source, Cloud-Native Storage Orchestrator for Kubernetes"
• SeaweedFS - Apache 2.0 - "SeaweedFS is a fast distributed storage system for blobs, objects, files, and data lake, for billions of files"
• Minio - AGPLv3 and commercial license for Object Storage.

Sorting sections

Each section should be sorted after it's been updated, here's how you can do that with bash.

cat | sort --ignore-case
# Copy / paste

# Control + D

Then paste the output back into the document.
