<p>I have deployment with volumes and limits presented above.
The problem is that kubernetes reject create pod with such error:</p>
<pre><code>    pods &quot;app-app-96d5dc969-2g6zp&quot; is forbidden:
     exceeded quota: general-resourcequota, requested: limits.ephemeral-storage=1280Mi, 
     used: limits.ephemeral-storage=0, limited: limits.ephemeral-storage=1Gi
</code></pre>
<p>As I've understood nodes have limit 1Gi for ephemeral-storage, but what is 1280Mi?
Is it correct, that kubernetes allocate some amount of memory for each volume?</p>

</code></pre>

<p>You namespace has a quota set to cap at 1Gi:</p>
<p><code>limits.ephemeral-storage  0     1Gi</code></p>
<p>The messaging said that the namespace will exceed the limit and reach 1.28Gi (1280Mi) with your deployment.</p>
<p>Reduce your limit to 700Mi to stay within the 1Gi limit and your pod will be schedule accordingly. Note that quota aggregates resource consumption in the namespace, not per pod basis.</p>
