# 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
|
|
|
|
```bash
|
|
./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.
|
|
|
|
```bash
|
|
./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.
|
|
```bash
|
|
./build-kernel.sh install
|
|
```
