AppEngine Flex deployment ERROR - INVALID_ARGUMENT: The following quotas were exceeded

Question

I have been unable to deploy a new Ruby service in my project for quite a while now. Everytime I try, I get this error:

ERROR: (gcloud.app.deploy) INVALID_ARGUMENT: The following quotas were exceeded: CPUS (quota: 0, used: 0 + needed: 1).

I have looked into the AppEngine Quotas page in the Console, but I cannot see any quotas that are reaching the limit. Here is a screenshot as proof:

AppEngine quotas do not show any CPUS quota. I could only find a similar quota in the general Quotas page, but still everything appears within the limit:

I have noticed that this fails even with the basic Ruby quickstart setup, this is the app.yaml used in the deployments:

runtime: ruby
env: flex
service: test
entrypoint: bundle exec ruby app.rb
manual_scaling:
  instances: 1
resources:
  cpu: 1
  memory_gb: 0.5
  disk_size_gb: 10

I appreciate any assistance with this, because I am honestly lost.

EDIT:

One of my colleagues suggested we tried deploying a GCE instance in the same region as the Appengine service (asia-south1), and we got the same error:

Quota 'CPUS' exceeded. Limit: 0.0 in region asia-south1.

Shouldn't this be a bug of the quotas page then? Why can I see that this region has quota available if, in reality, it doesn't?

Answer 1

As per this GCP official docs some new accounts and projects have global CPUs (All regions) quota that quota that applies to all regions and is measured as a sum of all your vCPUs in all regions.

For example, if you have 48 vCPUs remaining in a single region such as us-central1 but only 32 vCPUs remaining for the CPUs (All Regions) quota, you can launch only 32 vCPUs in the us-central1 region, even though there is remaining quota in the region.

You can get the quota for all regions from the quota page using the following Quota metric.

• Quota Metric: compute.googleapis.com/cpus_all_regions
• Limit Name: CPUS-ALL-REGIONS-per-project

Though, I can see that you are using only 1 CPU at us-cetral1-a and I hope you have required limit at All Regions. If you see that ALL Regions Quota limit is 0 then you need to increase the Quota using QIR. Please note that A support representative from the Compute Engine team will respond to your request within 24 to 48 hours.

If this is not a issue I suggest you to open a support case with GCP support team to investigate further.
