<p>my containers run in kubernetes and I saw lots of OOM from kubernetes Node log.
All the logs only have process id information. it's hard to dig what containers OOM. 
I don't know how to find container id by the host process Id.</p>

<p>Is there any way i can get host process id within container so that i can get a mapping.</p>

<p>this is node log</p>

<p>How to find pod name by the host process Id?</p>
<blockquote>
<p>nsenter -t $PID -u hostname</p>
</blockquote>
<p>Then you can find container id easily, I think.</p>
