<p>My Kubernetes user is not admin in the cluster. So I just cannot create a cluster role binding for filebeat service account. I am using auto discover  in filebeat. Can someone help how can I achieve this without clusterrole.</p>

<p>Unfortunately, it will not work the way you want it and the error you are getting indicates it perfectly:</p>
<pre><code>Performing a resource sync err kubernetes api: Failure 403 pods is forbidden: User &quot;system:serviceaccount:xxxxx:filebeat&quot; cannot list resource &quot;pods&quot; in API group &quot;&quot; at the cluster scope for *v1.PodList|
</code></pre>
<p>Notice the most important part which is: <code>at the cluster scope</code>. You could also check whether an action is allowed by executing the <a href="https://kubernetes.io/docs/reference/generated/kubectl/kubectl-commands" rel="nofollow noreferrer">kubectl auth can-i</a> command. More about that can be found in the <a href="https://kubernetes.io/docs/reference/access-authn-authz/authorization/" rel="nofollow noreferrer">Authorization Overview</a>.</p>
<p>This brings us to the differences between <a href="https://kubernetes.io/docs/reference/access-authn-authz/rbac/#role-and-clusterrole" rel="nofollow noreferrer">Role and ClusterRole</a>:</p>
<blockquote>
<p>An RBAC <code>Role</code> or <code>ClusterRole</code> contains rules that represent a set of
permissions. Permissions are purely additive (there are no &quot;deny&quot;
rules).</p>
<p>A <code>Role</code> always sets permissions <strong>within a particular namespace</strong>;
when you create a <code>Role</code>, you have to specify the namespace it belongs
in.</p>
<p><code>ClusterRole</code>, by contrast, <strong>is a non-namespaced resource</strong>. The
resources have different names (<code>Role</code> and <code>ClusterRole</code>) because a
Kubernetes object always has to be either namespaced or not
namespaced; it can't be both.</p>
<p><code>ClusterRoles</code> have several uses. You can use a <code>ClusterRole</code> to:</p>
<ul>
<li><p>define permissions on namespaced resources and be granted within individual namespace(s)</p>
</li>
<li><p>define permissions on namespaced resources and be granted across all namespaces</p>
</li>
<li><p>define permissions on cluster-scoped resources</p>
</li>
</ul>
<p>If you want to define a role within a namespace, use a Role; if you
want to define a role cluster-wide, use a <code>ClusterRole</code>.</p>
</blockquote>
<p>And between <a href="https://kubernetes.io/docs/reference/access-authn-authz/rbac/#rolebinding-and-clusterrolebinding" rel="nofollow noreferrer">RoleBinding and ClusterRoleBinding</a>:</p>
<blockquote>
<p>A role binding grants the permissions defined in a role to a user or
set of users. It holds a list of subjects (users, groups, or service
accounts), and a reference to the role being granted. A <code>RoleBinding</code>
grants permissions within a specific namespace whereas a
<code>ClusterRoleBinding</code> grants that access cluster-wide.</p>
<p>A <code>RoleBinding</code> may reference any Role in the same namespace.
Alternatively, a <code>RoleBinding</code> can reference a <code>ClusterRole</code> and bind that
<code>ClusterRole</code> to the namespace of the <code>RoleBinding</code>. If you want to bind a
<code>ClusterRole</code> to all the namespaces in your cluster, you use a
<code>ClusterRoleBinding</code>.</p>
</blockquote>
<p>So it is impossible to get the cluster scope permissions by using <code>Role</code> and <code>RoleBinding</code>.</p>
<p>You will most likely have to ask your Admin to help you solve this issue.</p>
