<p>We have a setup where we want to run 3 replicas of our Image. Each replica will be run in independent node and corresponding pods inside it.
So to summarize we will have 3 nodes in 3 separate JVMs and 3 corresponding pods.
Please provide following details,</p>
<ol>
<li>Can we fix POD IP and hostName always?</li>
<li>Can the Node IP and hostname be same as machine IP and hostname?</li>
<li>Can the same Machine IP and hostname be made POD IP and hostname?</li>
</ol>

<p><code>Can we fix POD IP and hostName always?</code></p>
<p>There is a <code>hostname</code> field for Pod that you can use. Using static IP for Pod is possible if the CNI plugin that you used support it. For example, Calico does <a href="https://projectcalico.docs.tigera.io/networking/use-specific-ip" rel="nofollow noreferrer">support</a> this use case. You need to check your CNI manual.</p>
<p><code>Can the Node IP and hostname be same as machine IP and hostname?</code></p>
<p>Yes.</p>
<p><code>Can the same Machine IP and hostname be made POD IP and hostname?</code></p>
<p>Pod name is up to you to set, but Pod IP is always in the range of Pod CIDR which is not applicable to machine IP.</p>
