Ansible roles for OpenSLX
Small collection of ansible roles to build a dracut-based initramfs for network boot via dnbd3.
Currently up-to-date versions of Ubuntu and CentOS are supported (version 18.04.1 and 7.5.1804, respectively).
The provided 'slx-builder.yml' playbook can be used, e.g. as an ansible provisioner in a packer template.
Included roles
slx-builder
Builds the dracut-based initramfs using the dnbd3-rootfs module (see systemd-init):
* Install needed build dependencies for the detected distribution
* Checkout git repository for systemd-init
* Build the initramfs using the 'build-initramfs.sh' script
* Extracts both initramfs and kernel to the subdirectory 'boot_files'
* Cleans up the systemd-init repository
This role is tagged to separate between the initialization of the required dependencies ('install' tag) and the build of the initramfs ('build' tag).
Depends on setup-dev-tools role (specified in slx-builder/meta/main.yml).
setup-dev-tools
Installs basic development packages for the detected distribution:
Ubuntu: build-essential, cmake, git
CentOS: "@development tools", cmake, git
disable-selinux
Disables SELinux. This is included on CentOS systems to be able to boot from the generated initramfs.
