Unable to create a Windows Core VM instance using gcloud

I wanted to create a Windows VM using gcloud command line.

Tried the "Equivalent Command Line" syntax - the syntax failed.

After some trial and error, discovered that the --create-disk list of parameters needs to be repeated (please observe the script below).

gcloud compute instances create ifworker-0 \
--project=ceng-test \
--zone=us-east4-c \
--machine-type=n2-standard-2 \
--network-interface=nic-type=VIRTIO_NET \
--network-tier=PREMIUM \
--maintenance-policy=MIGRATE \
--provisioning-model=STANDARD \
--service-account=the-service-account \
--scopes=https://www.googleapis.com/auth/cloud-platform \
--tags=ifworker-net-0 \
--create-disk=mode=rw \
--create-disk=size=40GB \
--create-disk=type=projects/ceng-test/zones/us-central1-a/diskTypes/pd-balanced \
--create-disk=boot=yes \
--create-disk=auto-delete=yes \
--create-disk=image=projects/windows-cloud/global/images/windows-server-2022-dc-core-v20220513 \
--no-shielded-secure-boot \
--shielded-vtpm \
--shielded-integrity-monitoring \
--reservation-affinity=any

However, even then the script is failing - the error is reproduced below.

ERROR: (gcloud.compute.instances.create) Could not fetch resource:
- Invalid value for field 'resource.disks[0]': '{
  "type": "PERSISTENT",  
  "mode": "READ_WRITE",  
  "boot": true,  
  "initializeParams": {  },  
  "autoDele...'. 
Boot disk must have a source specified.

Need some guidance here. Thanks for your attention and time.

As checked on your command, boot and image properties should be in the same line.

It should look like this.

--create-disk=boot=yes,image=projects/windows-cloud/global/images/windows-server-2022-dc-core-v20220513

Based on GCP's documentation the image properties should be included in the same line with --create-disk=[PROPERTY=VALUE,…] parameters, specifying the name of the image that will be initialized.

Below is the command that worked on my end:

gcloud compute instances create ifworker-0 \
--project=<project_name> \
--zone=us-east4-c \
--machine-type=n2-standard-2 \
--network-interface=nic-type=VIRTIO_NET \
--network-tier=PREMIUM \
--maintenance-policy=MIGRATE \
--provisioning-model=STANDARD \
--service-account=the-service-account \
--scopes=https://www.googleapis.com/auth/cloud-platform \
--tags=ifworker-net-0 \
--create-disk=mode=rw \
--create-disk=size=40GB \
--create-disk=type=projects/ceng-test/zones/us-central1-a/diskTypes/pd-balanced \
--create-disk=boot=yes,image=projects/windows-cloud/global/images/windows-server-2022-dc-core-v20220513 \
--create-disk=auto-delete=yes \
--no-shielded-secure-boot \
--shielded-vtpm \
--shielded-integrity-monitoring \
--reservation-affinity=any

Note: Change <project_name> and/or service account details.

For "gcloud compute instances create" there should be only one --create-disk line per disk. In other cases multiple disks are created. As we want only one disk, there should be only one line, with all parameters delimited by ",".

The correct example follows.

gcloud compute instances create ifworker-0 \
--project=<project_name> \
--zone=us-east4-c \
--machine-type=e2-micro \
--network-interface=nic-type=VIRTIO_NET \
--network-tier=PREMIUM \
--maintenance-policy=MIGRATE \
--provisioning-model=STANDARD \
--scopes=https://www.googleapis.com/auth/cloud-platform \
--tags=ifworker-net-0 \
--create-disk=mode=rw,size=40GB,type=projects/<project_name>/zones/us-central1-a/diskTypes/pd-balanced,boot=yes,auto-delete=yes,image=projects/windows-cloud/global/images/windows-server-2022-dc-core-v20220513  \
--no-shielded-secure-boot \
--shielded-vtpm \
--shielded-integrity-monitoring \
--reservation-affinity=any
