<p>I run this command go get an interactive shell inside a pod in kubernetes:</p>

<pre><code>kubectl run my-shell --generator=run-pod/v1 --rm -it --image alpine -- sh
</code></pre>

<p>That works just fine, but often I do run one more command in the interactive shell after it's up: </p>

<pre><code>apk add curl
</code></pre>

<p>I cannot figure out how to combine this commands so that I get an interactive shell after the curl is installed. Is it possible to do? I tried some other approaches like <code>-c</code> argument to the shell, but it finishes execution after the install of curl.</p>

<p>Using <code>sh -c "apk add curl &amp;&amp; sh"</code> works for me:</p>

<pre><code>$ kubectl run my-shell --generator=run-pod/v1 --rm -it --image alpine -- sh -c "apk add curl &amp;&amp; sh"
If you don't see a command prompt, try pressing enter.
