<p>I understand that a pod can have multiple containers. But, I am trying to find if there is a max limit on the number of containers within a pod. I have googled around, but could not find an answer.</p>

<p>AFAIK, there is no such pod-specific limit. Though there are some cluster-specific criteria (k8s v1.21) like:</p>
<ul>
<li>No more than 110 pods per node</li>
<li>No more than 5000 nodes</li>
<li>No more than 150000 total pods</li>
<li>No more than 300000 total containers</li>
</ul>
<p><strong>N.B.</strong>: Since a pod can be scheduled to a single node, you are also limited by node resources (ie. cpu, memory). So, when you increase the number of containers of a pod, make sure that your node has enough resources to accommodate your pod.</p>
