NixOS on Azure

Run NixOS on an Azure Gen 2 VM

---

Preparation

1. Set your username in the flake.nix file
2. use direnv or run nix develop
3. run az login and login with your Azure credentials
4. Create an RSA SSH key pair (id_rsa) - ed25519 keys are not supported by Azure

Upload image

it can take a while to upload the .vhd (for me it is +/- 50 min),
if the upload time-out; you may want to change the token duration.
also don't look at the azcopy log file, it spams 500 errors but these can be ignored..

./upload-image.sh --resource-group images --image-name nixos-gen2

Create VM

./boot-vm.sh --resource-group vms --image nixos-gen2 --vm-name nixos

Build image (only)

nix build .#azure-image --impure

SSH into server

ssh -i ~/.ssh/id_rsa <username>@<public_ip>

• username you have set in the flake.nix file
• public IP will be printed with running the boot-vm.sh script
