hostKernel property

Host operating system kernel used for on-demand builds in the build project. This setting controls the kernel of the underlying build host. It does not change the build environment operating system, which is determined by the image you specify. Valid values: LINUX_KERNEL_4 (runs on an Amazon Linux 2 host, kernel 4.x), LINUX_KERNEL_6 (runs on an Amazon Linux 2023 host, kernel 6.x), LINUX_KERNEL_LATEST (runs on the latest supported host kernel). Applies to the LINUX_CONTAINER, ARM_CONTAINER, LINUX_EC2, and ARM_EC2 environment types; not applicable to Windows, Lambda, or Mac environment types. If not specified, CodeBuild selects a default.
