LinuxCOE Architecture

• Design Station−where users interacts with LinuxCOE

• SystemDesigner WebUI• Installation Media Repository (aka

waystation)• Target Install System(s)

−ultimate objective

Major Deployment Components

November 3, 200612

November 3, 200613

November 3, 200614

LinuxCOEFeature Set

November 3, 200615

LinuxCOEFeature Set

• generate boot images for network or local media based installations, by managing design profiles

• save profiles that store custom installation preferences for later re-use

• retrofit already deployed systems by overlaying bundles of packages for other value-add components

• replay, from a desired system, recreate the boot image for deployment on another system

November 3, 200616

November 3, 200617

LinuxCOE

• Software selection− distribution-defined sets

− value-add modules/bundles

• Disk partitioning− simple or advanced

• Patching− mechanism ( built-in, apt, yum )

− at first build, subsequent frequency

• Post-install scripting

Profile Management

November 3, 200618

LinuxCOE

• Preferences− fixed or DHCP target

− media source (network waystation or local), protocol

− network adapter

• Localizations− media source ( network waystation or local )− time zone, language

• Profile (or equivalent selections)• Passwords, summary, download page

Boot Image

LinuxCOE use case

November 3, 200620

LinuxCOE

• Selection of value-add bundles• Summary, download page

Retrofit

November 3, 200621

LinuxCOE Waystation

• Same or distinct host from SystemDesigner instance

• Typical alternatives−reference another's maintained repository

• default configured setup of SystemDesigner

−create localized repository• mirror another / public repository to minimize network

latency

• obtain ISO media, create local indices

Deployment Tactics

November 3, 200622

LinuxCOEDeep Dive

November 3, 200623

LinuxCOE

• Hosting requirements• Under the hood• Extending SystemDesigner

−Modules−Alternate Configurations−Integrations

• Restricting SystemDesigner

Deep Dive

November 3, 200624

LinuxCOE

• Hardware− minimal, anything capable of running supported

operating system and applications

• Operating System− current support for Linux only (loopback mount,

mkisofs)

• Application− common commands

− perl, web server (Apache)

− mkisofs, palo, sudo (depending on versions and architectures vended)

Hosting requirements

November 3, 200625

LinuxCOE

• SystemDesigner− a Perl, CGI application that typically runs under

Apache

− WebUI• a front-end script for each mode

• a set of back-ends for bootimage creation, corresponding to Kickstart, Autoyast, Preseed specifics

− per distribution/revision/architecture set of configuration files

− overall configurable settings

Under the hood

November 3, 200626

LinuxCOE

• Overlay of main configuration + select overrides

• simple text file referenced across modes via− <url>?defs=SomeOverrideFile

• Provides ability to use same codebase for multiple audiences, yet present different environment

Alternate Configurations

November 3, 200627

LinuxCOE

• Hierarchy of value-add components− Module ( repository )

• Bundle ( collection of one or more packages)

− Package (discrete installable item )

• Specific to distribution/revision/architecture or can be wildcarded

• Referenced by main configuration file, and included in WebUI as relevant at runtime

Modules

November 3, 200628

LinuxCOE

• Since modular, can readily be integrated with other processes− SystemDesigner can be called from HP-SIM and

vend images compatible with Smart Start Scripting Toolkit ( SSSTK ) => discovery, design, install on first boot

− Conceptually easy to integrate with generic PXE installation environment

− Future work to integrate, or at least interoperate with MondoRescue, and other FLOSS components

Integrations

Monitoring services(HP SIM / Nagios / OCS)

Internet services (IP management, software mirroring, network boot support)

Hardware Platforms (Proliant / Integrity / Carrier Grade)

Automatic Deployment and imaging services(LinuxCOE, MondoRescue, mrepo)

Hardware configuration services

Linux Distributions

Virtual Platforms (Xen / VMWare / QEMU)

November 3, 200630

LinuxCOE

• Using main configuration file, can− specify “default” settings that become default

selections

−specify “show only” selections to streamline interface

− using alternate configurations, can effectively filter down ( or provide superset ) of options

Restricting SystemDesigner

November 3, 200631

LinuxCOEFutures

November 3, 200632

LinuxCOE

−Plugins for OpenQRM (done)

−Whitepaper for integration of HP SIM, SSSTK, LinuxCOE, and PSP (about to publish)

−Add Mandriva as a supported distribution, investigating others

−Integrate with Mondorescue, network services as part of dploy.org

• <insert your suggestions here> :)
