Sorry, I should have made it clearer. Yes, I'm talking about the Linux kernel on the host that's running Docker containers. If I use the default Ubuntu kernel, it contains a bunch of unnecessary functionality. Is there a tool that I can use to configure the host kernel to only contain the absolutely necessary functionality required by the Docker container image?

In my opinion you're wasting your time. The Ubuntu kernel is very modular to begin with and only needed functionality for the hardware you're booting on is going to load anyways. Just use the stock config and do your Docker work as is. You're going to be more productive not chasing down this yak-shaving pursuit that will get you very little benefit to begin with. ¯\_(ツ)_/¯

  And if you really seriously MUST have this optimization you're after… Gentoo or LFS are probably better suited for the job. Again, that's a lot of time to waste for very little ROI.

    Another one that came to mind… Alpine Linux.

Linux From Scratch[0] is one good option. Also, Ubuntu offers Ubuntu Core[1], a minimal distribution. It is for IoT though. You can give it a try. [0] http://www.linuxfromscratch.org http://www.linuxfromscratch.org [1] https://ubuntu.com/core https://ubuntu.com/core
