# 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
|
||||
```
|
||||
|
||||
