v0.7.1. Kernel Headers

There are two ways to include the service file. It can be hosted somewhere and then referenced via a cloud-config file.

#cloud-config
rancher:
  services_include:
    https://raw.githubusercontent.com/rancher/os-services/embedded-headers/k/kernel-headers.yml: true

The service can also be directly embedded in a cloud-config file.

#cloud-config
rancher:
  services:
    kernel-headers:
      image: rancher/os-headers:v0.7.1-embedded
      labels:
        io.rancher.os.detach: "false"
        io.rancher.os.after: network
      volumes:
      - /usr/src:/usr/src
      - /lib/modules:/lib/modules
      - /usr/bin/ros:/usr/bin/ros

The image for this service is available in rancher/os-headers:v0.7.1-embedded. It can also be built manually with the following two files.

FROM rancher/os-base:v0.7.1
ENV KERNEL_HEADERS_URL https://github.com/rancher/os-kernel/releases/download/Ubuntu-4.4.0-47.68-rancher1/build.tar.gz
RUN wget -O /build.tar.gz $KERNEL_HEADERS_URL
COPY headers.sh  /
CMD ["/headers.sh"]

#!/bin/bash
set -e

DIR=$(readlink /lib/modules/$(uname -r)/build)
STAMP=${DIR}/.done
VER=$(basename $DIR)

if [ -e $STAMP ]; then
    echo Headers already installed in $DIR
    exit 0
fi

mkdir -p $DIR
cat /build.tar.gz | gzip -dc | tar xf - -C $DIR
touch $STAMP

echo Headers installed at $DIR
