I'm using Cloud Build to start a Google Cloud Compute Engine VM.
Here's the command I got from Compute Engine by selecting options in the UI and getting the "Equivalent command line", notice the --enable-display-device:
gcloud compute instances create-with-container my-vm
--project=XXX
--zone=us-central1-a
--machine-type=g1-small
--network-interface=network-tier=PREMIUM,subnet=default
--maintenance-policy=MIGRATE
--provisioning-model=STANDARD
--service-account=XXX
--scopes=https://www.googleapis.com/auth/cloud-platform
--enable-display-device
--image=projects/cos-cloud/global/images/cos-stable-97-16919-29-16
--boot-disk-size=10GB
--boot-disk-type=pd-balanced
--boot-disk-device-name=checkmate-dev
--container-image=XXX
--container-restart-policy=always
--no-shielded-secure-boot
--shielded-vtpm
--shielded-integrity-monitoring
--labels=container-vm=cos-stable-97-16919-29-16
This command is placed in the args field of the cloudbuild.yaml which seems to run as intended until Cloud Build spits out an error:
unrecognized arguments: --enable-display-device (did you mean '--boot-disk-device-name'?)
I don't understand because this flag came from Compute Engine so I figure it's valid. The flag is not actually in the docs in https://cloud.google.com/sdk/gcloud/reference/compute/instances/create-with-container.
But if I use the Compute Engine UI to make a "New VM Instance" as opposed to a container VM, then the flag appears in the command line.
