Couchbase Beta 6.5 beta Open files 1024 restriction

Hi ,
I am getting below in K8s POD logs . I need to perform some test for which I need open files to be increased . How can I do that ? I have tried steps to modify limits.conf and its not working and not reflecting

kubectl logs cb-rate360-adc-0000

The maximum number of open files for the couchbase user is set too low (1024).
It must be at least 70000.

Normally this can be increased by adding the following lines to
/etc/security/limits.conf:

couchbase soft nofile
couchbase hard nofile

Where is greater than 70000. The procedure may be totally
different if you’re running so called “non-root/non-sudo install” or
if you’ve built Couchbase Server from source.

Nothing to do with us (at present), have a read of https://github.com/kubernetes/kubernetes/issues/3595 and see if anything presents itself.

Not sure we are talking in same context . How this is a K8s issue and not Couchbase image for 6.5 beta version ?
If this is K8s issue then how the open files limit is above 70,000 in Couchbase 6.0 image build with helm chart ?
I can’t digest it well enough as may be I am thinking at same line you are. All I am thinking is that , Couchbase 6.5 beta version image issue to not allow more open files.

I have similar issue with CB 6.0 environment as well . I build cluster with 4 nodes in K8s and all happily up and running for couple of days and suddenly one day my multithreaded execution of N1QL query started throwing issue on Open files # and when I checked 2 of the nodes Open files shows 1024 however other two nodes have the much higher number. I didn’t play around with any OS setup for those 2 node. This sounds like story but it happen in reality and I wonder if CB image and OS is readonly file system who edited this file limits to make it 1024 from 1056780 limit . Can you shed some lights what could happen with this Open Files limit changed suddenly ??
thanks
