<p>I have this Terraform GKE cluster with 3 nodes. When I deploy this cluster all nodes are localised in the same zones which is <code>europe-west1-b</code>.</p>

</code></pre>
<p>And would like to know if it's possible to deploy each node in a different zone.
If yes how can I do it using Terraform?</p>

Kevin
<p>Simply add the following line</p>
<pre><code>resource &quot;google_container_cluster&quot; &quot;primary&quot; {
  name = &quot;cluster&quot;
  location = &quot;us-central1&quot;
  initial_node_count       = &quot;3&quot;
</code></pre>
<p>in order to create a <a href="https://cloud.google.com/kubernetes-engine/docs/concepts/regional-clusters" rel="nofollow noreferrer">regional cluster</a>. The above will bring up 9 nodes with each zone (f a b) containing 3 nodes. If you only want 1 node per zone, then just change initial_node_count to 1.</p>
