lxc-nofiles-limit

[Shibili K]

How do I set ulimit -n more than 65536 in a lxc (centos 7 template) running on Proxmox 6.0.4 version?

I can setup unto 65536 using /etc/security/limit.conf. How do I set a value upto 100000?

Hi,
try adding the following line to your container configuration file (in /etc/pve/lxc/<ID>.conf):

lxc.prlimit.nofile: 100000

Then you should be able to raise the limit within the container to 10000 as well.

Thank you,
If we add lxc.prlimit.nofile: 100000 in /etc/pve/lxc/<ID>.conf is it required lxc restart? or is it reflect without restart lxc?

If you really don't want to restart, use

pstree -p $(lxc-info -Hp -n <ID>)

to see the process tree of your container, use

prlimit -p <PID>
prlimit --nofile=100000 -p <PID>

to check and set the limits of the relevant process(es).
