<p>I need to make my Linux container running (without any app or service in it) so I can enter /bin/bash and modify some local linux files before I actually <strong>manually</strong> run my app from the container shell (this is  purely for some debugging purposes so I do not want any modifications in my image itself, please do not suggest that as an option)</p>
<p>I have defined my Kubernetes YAML file hoping that I would be able to execute simple <code>command: [&quot;/bin/bash&quot;]</code> but this does not work because it will execute command and Exit the container. So how I can make it not to exit so I am able to <code>exec</code> container?</p>

<p>When I want to see what is going on after the deployment I can notice:</p>

<p><strong><code>kubectl logs $POD</code></strong> doesn't return anything
and <code>kubectl describe pod $POD</code> output is:</p>

<p>You just need to run some long/endless process for the container to be up. For example you can read a stream, that'll last forever unless you kill the pod/container:</p>
<pre><code>command: [&quot;/bin/bash&quot;, &quot;-c&quot;]
args: [&quot;cat /dev/stdout&quot;]
</code></pre>
