Infrastructure📋

The .NET projects that build, provision, and orchestrate the VMs and images the rest of the stack runs on.

Vos (FrenchExDev.Net.Vos)📋

VM orchestration framework for managing virtual machine instances across backends. Supports up, halt, destroy, provision, snapshot operations with configuration merging, group execution, and a contributor-based extensibility model.

var machine = vos.Machine("dev-docker-host")
    .WithType<AlpineDockerHost>()
    .WithContributors(alpine, docker, sharedFolders);

await machine.UpAsync(ct);
await machine.ProvisionAsync(ct);

Machines are composed from typed contributors that layer configuration: Vos.Alpine provides VirtualBox defaults (SATA SSD, nested virtualization, NIC promiscuous mode, Vagrant plugins), and Vos.Alpine.DockerHost adds Docker provisioning (installation, docker-compose, openrc services, shared folder setup).

Packer.Alpine (FrenchExDev.Net.Packer.Alpine)📋

Alpine Linux provisioning helpers for Packer builds. Provides answer file generation for unattended Alpine installs, base system setup scripts, Vagrant SSH key injection, and Alpine-specific provisioning steps.

Packer.Alpine.DockerHost extends this with Docker provisioning: installs Docker daemon, docker-compose, configures openrc services, and sets up the host as a ready-to-use Docker environment — producing golden VM images that Vos can instantiate.

Together with the Packer BinaryWrapper, this forms a type-safe image building pipeline: Packer (typed CLI) → Packer.Alpine (OS config) → Packer.Alpine.DockerHost (Docker layer) → VM image.
