[Buildroot] [RFC PATCH v1 0/1] New "docker" ready qemu config

[Francis Laniel]

Hi.


First, I hope you are fine and the same for your relatives.

In this contribution, I added a new qemu config for x86_64.
This configuration is mainly based on qemu_x86_64_defconfig but it adds kernel
CONFIG_ to be able to use docker.
It also adds package related to docker like DOCKER_CLI and CONTAINERD.

The CONFIG_ options added were checked with moby check-config script [1].

I was able to build and execute the image with start-qemu.sh:
Welcome to Buildroot
buildroot login: root
# docker run --rm hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
2db29710123e: Pull complete
Digest: sha256:10d7d58d5ebd2a652f4d93fdd86da8f265f5318c6a73cc5b6a9798ff6d2b2e67
Status: Downloaded newer image for hello-world:latest

Hello from Docker!
This message shows that your installation appears to be working correctly.

Sadly, the image has to a bit big (more than 300M) but I think it is fine since
this image will only be used for virtualization.

If you say any way to improve this contribution, feel free to share it!
