Why doesn't Compute VM COS metadata not get carry over to "Equivalent command line"?

Question

I'm deploying a container to a Container Optimized OS or COS on Google Compute.
I want to specify Logging and Monitoring for the VM. There are 2 ways to do this:

• Specify metadata flags:

  

• Mark the checkboxes

  

But when I then click on "Equivalent command line", there's no indication of these options.

Am I just misinterpreting something here or am I not allowed to specify these flags in the command?

I tried with the non-COS VM instance and the expected metadata flag showed up to indicate the metadata. But this does not show up in the COS command.

gcloud compute instances create instance-1 \
    ...
    --metadata=MY_TEST_FLAG=test_value 

Answer 1

Yes. When using container optimized OS images while creating a VM this issue is coming, But this is for command line code only. REST equivalent is generated properly, As a work around for this you can add the metadata flag to the generated command as mentioned below.

--metadata=google-logging-enabled=true,google-monitoring-enabled=true
