To run, you need to specify AWS credentials in ENV

packer build packer.json

Follow installation instruction for Azure CLI az. Login for managing resources:

$ az login

Steps below follows HOWTO. Create group as container for result image. Value packer is from property managed_image_resource_group_name of azure-arm packer's builder. Value eastus is property location of azure-arm (Azure has two kind notation for the same location).

$ az group create -n packer -l eastus

Packer allocates resources on its own. It requires access to subscription. Obtain id.

$ az account show --query "{ subscription_id: id }"
{
  "subscription_id": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx"
}

Create credentials for packer.

$ az ad sp create-for-rbac --role Contributor --scopes /subscriptions/<subscription_id> --query "{ client_id: appId, client_secret: password, tenant_id: tenant }"
{
    "client_id": "f5b6a5cf-fbdf-4a9f-b3b8-3c2cd00225a4",
    "client_secret": "0e760437-bf34-4aad-9f8d-870be799c55d",
    "tenant_id": "72f988bf-86f1-41af-91ab-2d7cd011db47"
}

Set environment variables.

compute.admin is not sufficient for packer. Use admin role instead.

ncp config profile create packer
ncp config set service-account-key path/to/service_account.json
ncp config set endpoint api.ai.nebius.cloud:443
export PKR_VAR_nebius_token=$(ncp iam create-token)

export PKR_VAR_nebius_folder_id=...
export PKR_VAR_nebius_subnet_id=...
# no CUDA
packer build -only yandex.nebius -var image_version=0.4rc3 .
# with CUDA
packer build -only yandex.nebius-cuda -var image_version=0.4rc3 .
