Build Kata Containers Kernel
This document explains the steps to build a compatible kernel with Kata Containers. To do this use build-kernel.sh, this script automates the process to build a kernel for Kata Containers.
Setup kernel source code
./build-kernel.sh setup
The script ./build-kernel.sh tries to apply the patches from
${GOPATH}/src/github.com/kata-containers/packaging/kernel/patches/ when it
sets up a kernel. If you want to add a source modification, add a patch on this
directory.
The script also adds a kernel config file from
${GOPATH}/src/github.com/kata-containers/packaging/kernel/configs/ to .config
in the kernel source code. You can modify it as needed.
Build the kernel
After the kernel source code is ready it is possible to build the kernel.
./build-kernel.sh build
Install the Kernel in the default path for Kata
Kata Containers uses some default path to search a kernel to boot. To install on this path, the following command will install it to the default Kata containers path.
./build-kernel.sh install
