How can I deploy VM images from Container Registry using Google Cloud - docker

Question

I can see that my VM images are available in Google Container Registry following execution of the commands :
docker tag sutechnology/transcode eu.gcr.io/supereye/transcode
docker push eu.gcr.io/supereye/transcode
gcloud auth configure-docker docker push eu.gcr.io/supereye/transcode
Although I can see the images, I haven't been able to use this image while creating a new instance in Google Compute Engine. How can I use the image that I see in Container Registry while creating a new VM instance? Here below is my full config :
machine_type = "zones/europe-west2-b/machineTypes/n1-standard-1"
disk_type = "zones/europe-west2-b/diskTypes/pd-standard"
config = {
'name': name,
'machineType': machine_type,
# Specify the boot disk and the image to use as a source.
'disks': [
{
'boot': True,
'autoDelete': True,
'initializeParams': {
'sourceImage': source_disk_image,
}
}
],
# Specify a network interface with NAT to access the public
# internet.
'networkInterfaces': [{
'network': 'global/networks/default',
'accessConfigs': [
{'type': 'ONE_TO_ONE_NAT', 'name': 'External NAT'}
]
}],
# Allow the instance to access cloud storage and logging.
'serviceAccounts': [{
'email': 'default',
'scopes': [
'https://www.googleapis.com/auth/devstorage.read_write',
'https://www.googleapis.com/auth/logging.write'
]
}],
# Metadata is readable from the instance and allows you to
# pass configuration from deployment scripts to instances.
'metadata': {
'items': [{
# Startup script is automatically executed by the
# instance upon startup.
'key': 'startup-script',
'value': startup_script,
'VIDEOPATH': videopath
}]
}
}
And instance creation function below :
compute.instances().insert(
project=project,
zone=zone,
body=config).execute()

Google Container Registry (GCR), is used for storing docker images, which is then used to create the containers NOT compute Engine machine.
For Compute Engine, either use the public Images or Custom Images Snapshots of existing machines.
