Installing new gentoo kernel in docker container

I am creating a new docker container to run OpenVpn in Gentoo OS. To make this I need configure the kernel with tun/tap module and install it:

cd /usr/src/linux

make menuconfig

Device Drivers ---> Network device support --->

[*]Network device support

Universal TUN/TAP device driver support // This option must be enabled

cd /usr/src/linux make && make modules_install

Now I need to install this kernel in the container and continue with the openVPN installation but not know how I do it.

Any suggestions?

Thanks

Solution

  • Docker work using the kernel of the host machine.

    If you want specific kernel capabilities you need to modify the host kernel.

    Then run your container using --privileged attribute or using the --lxc-conf parameter.
