Chrison.ProxmoxSharp.Api 9.2.2-preview.8

ProxmoxSharp

A C# API client for Proxmox VE — mostly code-generated from Proxmox's own published API schema, with a thin hand-written runtime for auth and transport.

dotnet add package Chrison.ProxmoxSharp
dotnet tool install -g Chrison.ProxmoxSharp.Cli   # the `proxmoxsharp` CLI

Built to be dogfooded by the Homelab hub's C#-native IaC (the Discover → Converge path). Design + roadmap live in the hub at docs/plans/BL-009-proxmoxsharp-codegen.md.

The generated client is regenerated on build (incrementally — only when the schema changes) and not committed.

The generated client is regenerated on build (incrementally — only when the schema changes) and not committed. Day-to-day work on the hand-written library doesn't regenerate.

• Read-only first — token auth, the read path (nodes / LXC / VM / storage / network) before any write/lifecycle.
• Schema is version-matched to our cluster (PVE 9.2.2) and pinned under src/ProxmoxSharp.Api/schema/.

Projects & versioning

The two packages move independently: bump the library for a new feature without touching the API version; bump the API when you regenerate from a new Proxmox release.

Build

Built with Fallout (Chris's C#/.NET build system, a NUKE successor). Targets: Compile → Test → Pack → Publish.

./build.sh              # default: Test (Compile regenerates ProxmoxSharp.Api from the schema, then compiles)
./build.sh Pack         # produce the Chrison.* nupkgs into artifacts/

Requires the .NET 10 SDK (see global.json) and GITHUB_PACKAGES_PAT in the environment (a PAT with read:packages on the Fallout-build org — the build restores Fallout.* from that feed, see nuget.config). CI (.github/workflows/ci.yml) runs ./build.sh Test on push/PR — a clean checkout regenerates the client fresh.

Use it

var client  = ProxmoxApi.Create(options);   // token auth + base URL + TLS handling
var version = await client.Version.GetAsVersionGetResponseAsync();
var nodes   = await client.Nodes.GetAsNodesGetResponseAsync();

CLI (proxmoxsharp)

A dotnet global tool (src/ProxmoxSharp.Cli) wrapping the library — usable from the shell. It's self-contained (bundles the library + generated client), so install needs only the ProxmoxSharp.Cli package, not its dependencies.

dotnet tool install -g Chrison.ProxmoxSharp.Cli   # from nuget.org (public)

export PROXMOX_BASE_URL="https://192.168.179.3:8006/api2/json"
export PROXMOX_TOKEN_ID="root@pam!token"
export PROXMOX_TOKEN_SECRET="…"
export PROXMOX_VERIFY_TLS=false

proxmoxsharp version     # PVE version
proxmoxsharp nodes       # list nodes
proxmoxsharp discover    # structured ClusterSnapshot as JSON

Refresh the schema (new Proxmox release)

pwsh src/ProxmoxSharp.Api/schema/refresh.ps1 -Node hpe-01   # writes apidoc.<ver>.js
# then update <Version> + the schema filename in ProxmoxSharp.Api.csproj, and rebuild

Dev token & secrets

Integration tests read a gitignored secrets.env (copy secrets.env.example). Use a dedicated read-only token, not broad creds. The helper creates one (privilege-separated, role PVEAuditor at /) and prints the secrets.env lines:

pwsh scripts/new-dev-token.ps1 -Node hpe-01

Packages

Published to nuget.org (public) under the Chrison.* prefix, via Trusted Publishing (OIDC — no stored API key):

So every merge to main ships a referenceable prerelease; tagging cuts a stable release. The library depends on the matching .Api. IDs use the Chrison.* prefix because the bare ProxmoxSharp ID is taken on nuget.org by an unrelated project; assembly names and namespaces stay ProxmoxSharp, so using ProxmoxSharp; is unchanged.

Consume from nuget.org like any public package. To track the latest prerelease, float it: <PackageReference Include="Chrison.ProxmoxSharp" Version="0.2.0-preview.*" />.

Status

M1–M5 done. Generated client reads the live cluster; ProxmoxDiscovery produces a structured ClusterSnapshot (nodes → LXC/QEMU/storage/network); the packages publish to nuget.org. Coverage: /version,/nodes,/cluster,/storage,/access (338 GET ops). Next: the hub consumes the package; BL-014 CLI; write path (BL-010).
