<p>Consider the following shell script, where <code>POD</code> is set to the name of a K8 pod.</p>
<pre><code>kubectl exec -it $POD -c messenger -- bash -c &quot;echo '$@'&quot;
</code></pre>
<p>When I run this script with one argument, it works fine.</p>
<pre><code>hq6:bot hqin$ ./Test.sh  x
x
</code></pre>
<p>When I run it with two arguments, it blows up.</p>
<pre><code>hq6:bot hqin$ ./Test.sh  x y
y': -c: line 0: unexpected EOF while looking for matching `''
y': -c: line 1: syntax error: unexpected end of file
</code></pre>
<p>I suspect that something is wrong with how the arguments are passed.</p>
<p><strong>How might I fix this so that arguments are expanded literally by my shell and then passed in as literals to the <code>bash</code> running in <code>kubectl exec</code>?</strong></p>
<p>Note that removing the single quotes results in an output of <code>x</code> only.
Note also that I need the <code>bash -c</code> so I can eventually pass in file redirection: <a href="https://stackoverflow.com/a/49189635/391161">https://stackoverflow.com/a/49189635/391161</a>.</p>

<p>I managed to work around this with the following solution:</p>
<pre><code>kubectl exec -it $POD -c messenger -- bash -c &quot;echo $*&quot;
</code></pre>
<p>This appears to have the additional benefit that I can do internal redirects.</p>
<pre><code>./Test.sh x y '&gt; /tmp/X'
</code></pre>
