<p>I am struggling to figure out whether the namespace created without limit-range can resources use up to maximum possible leaving issues for other namespaces.?</p>

<p>A LimitRange provides constraints that can:</p>
<ul>
<li><p>Enforce minimum and maximum computing resources usage per Pod or Container in a namespace.</p>
</li>
<li><p>Enforce minimum and maximum storage request per PersistentVolumeClaim in a namespace.</p>
</li>
<li><p>Enforce a ratio between request and limit for a resource in a namespace.</p>
</li>
</ul>
<p>So if a namespace is created without LimitRange there are no constraints and you can't enforce the use of minimum and maximum per Pod.</p>
