I am using GCE on Asia-Southeast-b with 2vCPU 10GM for my website I am trying to test CDN and LB, so was halfway to create an instance group in the US but it threw me an error no matter how.

Instance Group : Exceeded limit 'QUOTA_FOR_INSTANCES' on resource 'us-instance-group-1'. Limit: 8.0

This document from https://cloud.google.com/compute/quotas leads me to think it could be due to the zone that I choose, so I have tried to choose all multi zones in different regions and even single zone but didn't allow me to create one no matter how I select it seems (I can't say I tried all different combinations but almost all).

I chose the Instance template with the lowest spec N1-standard with CentOS7 + 20G standard disk.

Under this project, I have the 4 following service accounts associated with this.

Compute Engine default service account, Google APIs Service Agent, Compute Engine Service Agent, Myself as Owner

I went to IAM & Admin > Quotas > All green checked

  1. Is it because I am building this with free 300 credit?
  2. How do I check which zone available I should create the instance group on?
  3. What could be the reason? What did I do wrong?

Thank you

  • What is the max & min number of instances you're attempting to set in your instance group? Do you have already running instances out of the instance group? – Puteri Aug 15 '20 at 07:27
  • Yes I have 1 running instance for my website and this is the 2nd instance (not even instance but instance group) I am trying to create under this project. In the multiple zone, I tried 3 regions checked, 2, 1, and then unchecked multiple zone and switch to single zone.. however combination, it throws me the same message... Exceeded limit.... I don't quite get it.. That's why... – futureyoon Aug 15 '20 at 08:08

It seems to be the configuration you're setting in the Maximum number of instances.

For example, when you create an Instance Group, you set the Minimum number of instances and the Maximum number of instances. Even if you set as minimum 1 instance and you left the default value for Maximum number of instances (which is 10), it will always fail since it checks the pre-condition that the Maximum number of instances never exceeds the Quota for a region.

I reproduced this by setting Maximum number of instances to a value greater than my quota limit.

I suggest to change the value of Maximum number of instances to 3 and check if you can deploy the instance group.

  • Yes, you are absolutely right about this! I will have to set the "Maximum number of instances", the default is 10 which was the root cause to fail to create. I changed to 3, it successfully created the instance group! Thank you! – futureyoon Aug 17 '20 at 05:40

Currently, the issue is still going on I think it might be region issue, I have set it up to max 20, and the most I still can go is 8 instances.

I suggest recreating another project and using the previous project's custom image in your new project
