From 56200c41fbd573e0905d51217f45246d356e00a0 Mon Sep 17 00:00:00 2001 From: Pedro Alvarez Date: Thu, 4 Dec 2014 15:55:56 +0000 Subject: Add the ability to deploy installer systems and add examples. The installer-x86_64 system is a system that can be used to install other systems in an storage device. This system is intended to be booted by usb, pxeboot... to install a Baserock system in your local disk. The installer system requires the installer.configure extension to generate a configuration file located in /etc/install.conf. With this extension you can specify the following variables in a cluster morphology: - INSTALLER_TARGET_STORAGE_DEVICE: Target storage device to install the Baserock system. - INSTALLER_ROOTFS_TO_INSTALL: The location of the root filesystem that is going to be installed. - INSTALLER_POST_INSTALL_COMMAND: Commands that will be run after the installation finishes. It defaults to `reboot -f`. The installer-utils stratum is required to contain the installer-scripts chunk. This chunk contains the installer script that is going to be installed in /usr/lib/installer/installer.py The clusters/installer-build-system-x86_64.morph file defines the deployment of a installer system as a rawdisk image. This installer system will install a build-system-x86_64 located in /rootfs into the /dev/sda device. Also this cluster defines a subsystem which is the build-system that is going to end up in /rootfs on the installer system. --- clusters/installer-build-system-x86_64.morph | 46 ++++++++++++++++++++++++ installer.configure | 48 ++++++++++++++++++++++++++ strata/installer-utils.morph | 12 +++++++ strata/installer-utils/installer-scripts.morph | 4 +++ systems/installer-system-x86_64.morph | 22 ++++++++++++ 5 files changed, 132 insertions(+) create mode 100644 clusters/installer-build-system-x86_64.morph create mode 100755 installer.configure create mode 100644 strata/installer-utils.morph create mode 100644 strata/installer-utils/installer-scripts.morph create mode 100644 systems/installer-system-x86_64.morph diff --git a/clusters/installer-build-system-x86_64.morph b/clusters/installer-build-system-x86_64.morph new file mode 100644 index 00000000..b31caced --- /dev/null +++ b/clusters/installer-build-system-x86_64.morph @@ -0,0 +1,46 @@ +name: installer-build-system-x86_64 +kind: cluster +description: | + This is a cluster morphology that can be used to deploy + installer systems.
