<p>I am having an issue on GKE where all this error is being spewed from all name spaces. Not sure what might be the issue or how to troubleshoot this.</p>
<p>message: &quot;MountVolume.SetUp failed for &quot;<strong>volume-name</strong>-token-m4rtn&quot; : failed to sync secret cache: timed out waiting for the condition&quot;</p>
<p>It occurs for almost all pods in all namespaces. Has anyone come across this or have any ideas on how I can troubleshoot?</p>

<p>The error you are receiving points to be a problem with RBAC(Role-based access control) permissions, looks like the service account used by the pod does not have enough permissions.</p>
<p>Hence, the default service account within the namespace you are deploying to is not authorized to mount the secret that you are trying to mount into your Pod.</p>
<p>You can get further information on the following link <a href="https://kubernetes.io/docs/reference/access-authn-authz/rbac/" rel="nofollow noreferrer">Using RBAC Authorization</a>
You also can take a look at the <a href="https://cloud.google.com/kubernetes-engine/docs/how-to/role-based-access-control#define-and-assign" rel="nofollow noreferrer">Google’s documentation</a></p>
<p>For example, the following Role grants read access (get, watch, and list) to all pods in the accounting Namespace:</p>
<pre><code>apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
  namespace: accounting
  name: pod-reader
rules:
- apiGroups: [&quot;&quot;] # &quot;&quot; indicates the core API group
  resources: [&quot;pods&quot;]
  verbs: [&quot;get&quot;, &quot;watch&quot;, &quot;list&quot;]
</code></pre>
