                        [--defer]
                        [--force-string]

The 1th example of the child command would be to use it to 'create a template resource from a template object in the cli cache  see  az image builder create   output add   customizer add   help  and  az cache  h  for more information', the syntax is: # create and write template object to local cli cache
az image builder create --image-source {image_source} -n mytemplate -g my-group \
    --scripts {script} --managed-image-destinations image_1=westus --identity myidentity --defer

# add customizers and outputs to local cache template object via az image template output / customizer add
# one can also update cache object properties through generic update options, such as: --set
az image builder output add -n mytemplate -g my-group --output-name my-win-image-managed \
    --artifact-tags "is_vhd=False"  --managed-image winImage --managed-image-location eastus --defer

# send template create request to azure to create template resource
