# Incus VM Build and Deploy
## Build
```sh
nix build .#nixosConfigurations.fj-lxc-vm-x86_64.config.system.build.qemuImage --print-out-paths
nix build .#nixosConfigurations.fj-lxc-vm-x86_64.config.system.build.metadata --print-out-paths
```
## Deploy
```sh
incus image import --alias nixos-gen/custom/fj-lxc-vm-x86_64 ${metadatapath}/tarball/nixos-system-x86_64-linux.tar.xz ${qemuimageoutputpath}/nixos.qcow2
incus file push "$TOKEN_FILE" "$INCUS_INSTANCE/var/lib/forgejo/$TOKEN_FILE" --mode 400
```
## Runner machine types
Notice: The runners only run on VMs. No baremetal runners are available.
Hetzner/x86
Hetzner/aarch64
lxc-vm/x86
