<p>I want to run a local script within Kubernetes pod and then set the output result to a linux variable</p>
<p>Here is what I tried:</p>
<pre><code># if I directly run -c &quot;netstat -pnt |grep ssh&quot;, I get output assigned to $result:

cat check_tcp_conn.sh 
#!/bin/bash
result=$(kubectl exec -ti &lt;pod_name&gt; -- /bin/bash -c &quot;netstat -pnt |grep ssh&quot;)
echo &quot;result is $result&quot;
</code></pre>
<p>What I want is something like this:</p>
<pre><code>#script to be called:
cat netstat_tcp_conn.sh
#!/bin/bash
netstat -pnt |grep ssh

#script to call netstat_tcp_conn.sh:
cat check_tcp_conn.sh 
#!/bin/bash
result=$(kubectl exec -ti &lt;pod_name&gt; -- 
/bin/bash -c &quot;./netstat_tcp_conn.sh)
echo &quot;result is $result
</code></pre>
<p>the result showed <code>result is /bin/bash: ./netstat_tcp_conn.sh: No such file or directory</code>.</p>
<p>How can I let Kubernetes pod execute netstat_tcp_conn.sh which is at my local machine?</p>

<p>You can use following command to execute your script in your pod:</p>
<pre class="lang-sh prettyprint-override"><code>kubectl exec POD -- /bin/sh -c &quot;`cat netstat_tcp_conn.sh`&quot;
</code></pre>
