pub struct DockerBuildContext {
    pub context_dir: PathBuf,
    pub kernel_version: String,
}

Context directory structure for a Docker kernel build.

Fields

context_dir: PathBuf

Path to the build context directory.

kernel_version: String

Kernel version being built.

Implementations

impl DockerBuildContext

pub fn prepare( context_dir: &Path, kernel_version: Option<&str>, ) -> Result<Self, KernelError>

Prepare a Docker build context directory with the Dockerfile and kernel config.

Creates:

• <context_dir>/Dockerfile
• <context_dir>/kernel.config

pub fn build(&self) -> Result<Vec<u8>, KernelError>

Execute the Docker build and extract the resulting bzImage.

Requires Docker to be installed and accessible. The build may take 10-30 minutes depending on CPU and network speed.

Returns the bzImage bytes on success.
