Hi,

I have installed Alpine Linux to my Proxmox dev environment in a LXC container and am having an issue raising the file limits.

I have it installed on a reasonably busy haproxy server so I need to increase the file limits but I get the following error from this command:

ulimit -n 90000
ash: error setting limit: Operation not permitted

===


## Increase system file descriptor limit
fs.file-max = 65535


Am I doing something wrong?  Any help appreciated!

David

Hi David,

This is an LXC limitation.

Given you have the prerequisite LXC >=2.19, try this: `lxc config set containername limits.kernel.nofile 1024`

Hi Daniel,


I can't believe I didn't think to look there first!  I amended the lxc config file with:


lxc.prlimit.nofile: 30000


which is more than enough.  Thank you for the fast reply.  I'm loving Alpine so far, the boot times are unreal, I can see why it's so popular.


David
