Unable to make instance on Google Cloud Platform with startup-script-url

Question

I can't create instance in GCP with gcloud console:

1. If script local, everything it OK:

gcloud compute instances create app \
--boot-disk-size=10GB \
--image-family ubuntu-1604-lts \
--image-project=ubuntu-os-cloud \
--machine-type=g1-small \
--restart-on-failure \
--metadata-from-file startup-script=install.sh

2. If I user startup-script-url with gsutil URI, like this:

gcloud compute instances create app \
--boot-disk-size=10GB \
--image-family ubuntu-1604-ltsm \
--image-project=ubuntu-os-cloud \
--machine-type=g1-small \
--restart-on-failure \
--metadata-from-file startup-script-url=gs://mbps54/install.sh

Then I received:

ERROR: (gcloud.compute.instances.create) Unable to read file [gs://mbps54/install.sh]. [Errno 2] No such file or directory: 'gs://mbps54/install.sh' gsutil URI is gs://mbps54/install.sh

3. If I user startup-script-url with Public URL,like this:

gcloud compute instances create reddit-app \
--boot-disk-size=10GB \
--image-family ubuntu-1604-ltsm \
--image-project=ubuntu-os-cloud \
--machine-type=g1-small \
--restart-on-failure \
--metadata-from-file startup-script-url=https://storage.googleapis.com/mbps54/install.sh

I received:**

ERROR: (gcloud.compute.instances.create) Unable to read file [https://storage.googleapis.com/mbps54/install.sh]: [Errno 2] No such file or directory: 'https://storage.googleapis.com/mbps54/install.sh'

4. Here are my bucket settings

And I can open https://storage.googleapis.com/mbps54/install.sh from any other PC. Additionally, to make sure access is public, I did this:

gsutil defacl set public-read gs://mbps54
gsutil -m acl set -R -a public-read gs://mbps54

5. This bucket url is Public and opens from any PC https://storage.googleapis.com/mbps54/install.sh opens from other PC.

Could somebody help, what is wrong with my configuration and script?

You're using the --metadata-from-file flag, which expects you to supply a local file. If you want to specify a startup script from a URL instead, you want the --metadata flag, i.e.:

--metadata startup-script-url=URL

This is mentioned at https://cloud.google.com/compute/docs/startupscript#startupscriptrunninginstances under the gcloud tab.

Using the gcloud command-line tool, use the instances add-metadata command to add metadata to the instance. Use any of the available startup script keys:

--metadata startup-script=CONTENTS: supply the startup script contents directly by using this key.

--metadata startup-script-url=URL: supply a Cloud Storage URL to the startup script file by using this key. `--metadata-from-file

startup-script=FILE: supply a locally stored startup script file.

For example:

--metadata-from-file startup-script=PATH_TO_FILE

gcloud compute instances add-metadata EXAMPLE_INSTANCE \   --metadata
startup-script-url=gs://BUCKET/FILE ```
