<p>Totally new to GCP and trying to deploy first kubernetes cluster and getting below error.</p>

<p>(1) insufficient regional quota to satisfy request: resource "IN_USE_ADDRESSES": request requires '9.0' and is short '1.0'. project has a quota of '8.0' with '8.0' available. View and manage quotas at <a href="https://console.cloud.google.com/iam-admin/quotas?usage=USED&amp;project=test-255811" rel="noreferrer">https://console.cloud.google.com/iam-admin/quotas?usage=USED&amp;project=test-255811</a></p>

<p>Have already request for quota increase but I want to know what does this "8.0" limit mean? how many IP addressed are available in "1.0"? from where I can reduce the size of my network. I am using "default" Network and default "/20" Node Subnet options. </p>

<p>I had the exact same error and thought it was because of a global IP I claimed. The limit involved can be found
Under:</p>

<p>GCP Navigation => IAM &amp; admin => Quotas:</p>

<pre><code>Compute Engine API
Static IP addresses global
</code></pre>

<p>Apparently when creating a new cluster, 9 free IPs are needed.</p>

<p>An option seems to be to ask for the limit to be increase the limit under quotas, which seems the only option because by default the number of nodes created by the gcloud container clusters create command is 3 and it seems there is 3 static address allocated for each node.</p>

<p>If you really don't need all those static addresses you can specify 2 nodes which should only allocate 6 static addresses via the --num-nodes switch eg.</p>

<p>gcloud container clusters create  --num-nodes=2</p>

<p>After creation there are not 8 IP's used so the global IP that was removed can be re-added.</p>

<p>Ref: <a href="https://stackoverflow.com/questions/58942642/gke-insufficient-regional-quota-to-satisfy-request-resource-in-use-addresses">GKE: Insufficient regional quota to satisfy request: resource &quot;IN_USE_ADDRESSES&quot;</a></p>

<p>An easy way to get the whole cloud command is to click on the command line link in the lower left button. it shows the gloud console command.</p>

<p>You can easily change the --num-nodes option there.
I think the GUI was changed, it would be useful if Google aligns their defautl settings with their default UI options, so users do not get this message. </p>
