Inodes exhausting about docker-wireguard HOT 10 CLOSED

Uhh... Seems like bad news for me. Thank you for your help anyway.

I think there is no need to fix the kernel version detection problem for OpenVZ servers because it will not help with WG deploying. So closing the issue.

If we can identify why it's not showing your exact kernel, we'll fix it in the image.

Can you give us the specifics of the machine? You mentioned VPS, where is it hosted? Details? What OS? etc.

Also post the result of uname -a

from docker-wireguard.

Post a full container log taken right after container creation

Full log

from docker-wireguard.

Keeping investigation have found /etc/cont-init.d/30-config in the container with:

 if apt-cache show linux-headers-$(uname -r) 2&>1 >/dev/null; then
  apt-get install -y \
    linux-headers-$(uname -r) \
    wireguard

Is it actually right thing to do? Do we need all these kernels sources?

from docker-wireguard.

Lol, it's supposed to install headers for a single kernel, the one you're using. What's the result of uname -r?

from docker-wireguard.

4.15.0

from docker-wireguard.

On my laptop apt-cache show linux-headers-$(uname -r) returns exactly one kernel with uname -r returning 5.3.0-53-generic. And in case of VPS with uname -r returning 4.15.0 apt-cache returns that huge list of kernels. Can I fix it somehow without risk to stuck again after the next image update? Or should it be fixed by docker image developer?

from docker-wireguard.

uname -a
Linux linux.c7aebb.vps 4.15.0 #1 SMP Mon Nov 25 18:42:58 MSK 2019 x86_64 x86_64 x86_64 GNU/Linu

It is Ubuntu 18.04.4 LTS VPS hosted on Ethernet Servers OpenVZ. What else kind of details can help you?

from docker-wireguard.

Yeah, openvz is the issue. I'm not too familiar with it, but it seems that the containers share the kernel with the host, and that it's not possible to install kernel modules inside the openvz container/VM: https://stackoverflow.com/a/22468756

So even if you figured out your current issue, installed the right headers, it still wouldn't work as it wouldn't be able to install the kernel module for wireguard.
