how does it choose the manual zone?

You can specify the zone/region with gcloud command using --zone or --region switch.

Hey folks,

It’s indeed an interesting question to pursue an answer as I created my first VM some months ago and now I just created another one to execute some tests. 

$ gcloud compute instances list  
myvm  us-east1-c  n1-standard-1       RUNNING

It has picked the same zone as before and I don’t really see that set in any configurations I can recall about:

$ gcloud config list --all | grep zone  
zone (unset)  
Your active configuration is: [cloudshell-12243]  
zone (unset)  

$ gcloud config list

disable_update_check = True  
gce_metadata_read_timeout_sec = 5  
account = xx  
disable_usage_reporting = True  
project = pimballeke-new-project005  
environment = devshell  
Your active configuration is: [cloudshell-12243]
$ gcloud config configurations list  
cloudshell-12243  True                pimballeke-new-project005

How does it pick a zone when flags as –zone and –region are omitted of the command?



OK, it seems the answer is really what Tuan LE mentioned right above my last message to this thread. I would say that this is something like your account has "default" VPC Network since to very start, when it’s created. So, based on that, docs says:

The default region and zone settings affect only client tools, such as the gcloud command-line tool and the Google Cloud Console. When you use these tools to construct your requests, the tools help you manage resources by automatically selecting the default region and zone.

When you use the Cloud Console to create regional or zonal resources like addresses and instances, Compute Engine sets the region and zone fields for you. You can accept the pre-populated values, or explicitly change one or both of the values.

When you use the gcloud tool, omit setting the –region and –zone flags to use the default region and zone properties for the new project.

You can always change the default region and zone settings in the metadata server, override the default region and zone locally for the gcloud tool, or override the settings manually for each request in either the gcloud tool and the Cloud Console.


I didn’t test, but, I would like to soon remove the default VPC and create another one on another region with some subnets on some zones so that I can create a new VM omitting the –zone and –region.
