How to run different kernel versions with Docker?

One possible way to run different kernel versions in Docker typically involves using virtualization technology, such as employing QEMU.

1. Firstly, you need to install QEMU in Docker using the following command.

apt-get update
apt-get install -y qemu-user-static

1. Next, you need to download the required kernel version and add it to the Docker image. Download links for various kernel versions can be found on https://www.kernel.org/.
2. Next, you need to copy the QEMU binary files into the Docker image. This can be achieved using the following command:

docker run --rm --privileged multiarch/qemu-user-static --reset -p yes

1. execute a Docker container

docker run --rm -it --entrypoint=/bin/bash <image_name>:<tag>

Please note that this method may require some additional configuration and debugging, depending on the kernel version and Docker environment you choose. It is recommended to try this method in a testing environment and make adjustments as needed.
