The SUSE Approach

SUSE design principles:

• Open source and open

development

• APIs

• Standards based (protocols,

languages, etc.)

• Enterprise focus

8

SUSE Components– Open Build Service

• Supports all major Linux distributions and

software packaging formats (rpm, deb,

containers, installation media, images)

• Support multiple architectures (i586,

x86_64, aarch64, ppc64, ppc64le, s390x)

• Web client and a CLI (osc)

• Allows for simple package creation

• Add external software repositories

• Build packages locally or on source server

• Collaboration via

branching/merging/review/commit -

request tracking

Kiwi – Image creation

• Developed and hosted by openSUSE

• Portal page: http://en.opensuse.org/Portal:KIWI

• Can create for multiple architectures

• Can create for multiple distributions

• Can be deployed to physical, virtual and cloud

• vmdk, qcow2, vhd, ovf, raw, lxc, Docker

How Do I Build It?The Easy Way

SUSE Studio

Two ways to get it:

• SUSE Studio Onsite: https://www.suse.com/products/susestudio/

• SUSE Studio Online: http://www.susestudio.com

Provides a simplified, web-

based user interface for Kiwi

Advanced Systems Management ModuleMachinery

16

OpenQA

• Automated test

infrastructure

• Used by openSUSE and

SUSE Linux Enterprise

• Ability to test various code

paths / installation options

• Basic concepts: “jobs,”

“needles,” (png + json)

• Output: log files, pictures,

video

https://en.opensuse.org/openSUSE:OpenQA

17

• Yearly Release

• Deliver new compiler and toolchain

• GCC (GNU Compiler Collection) development tools via Toolchain Module

• GCC runtime libraries, binutils, gdb as updates for SUSE Linux Enterprise core

• 2016 update of Toolchain Module for SUSE Linux Enterprise 12

• GCC 6.2 with C, C++, Fortran support

• Binutils 2.26

• Gdb 7.11

• Package build compiler (GCC 4.8) stays as default

Toolchain Module for SUSE Linux Enterprise 12SUSE Linux Enterprise 12 SP2

18

Containers module

Enterprise Ready

• Pre-build and signed images from a trusted source

• Full control over your data: On-premise registry, authentication

• Application Runtime for SUSE Linux Enterprise 11 and 12

Integration and management of Containers

• Integration with SUSE Manager and SUSE OpenStack Cloud

• Unified tooling, independent of the “virtualization” mechanism

– YaST, sle2docker, zypper-docker

– Portus

What is SUSE Linux Enterprise MicroOS

SLE MicroOS is a modern Linux

Operating System, designed for

containers and optimized for large

deployments.

MicroOS inherits the SLE knowledge

while redefining the operating system

into a small, efficient and reliable

distribution.

SUSE OpenStack

Cloud

MicroOS

33

What problems are we trying to solve with MicroOS?

A small and easy to manage/upgrade OS

Organizations using containers need

Ability to quickly setup/manage a cluster of nodes

Always up-to-date Operating System

Transactional updates

42

SUSE Linux Enterprise for Raspberry PiDifferences Compared to Raspbian

Based on Upstream Kernel

While Raspbian uses a kernel with modifications especially for the Raspberry Pi, SUSE Linux

Enterprise Server for the Raspberry Pi uses the SUSE Linux Enterprise kernel for AArch64.

64-bit ARM AArch64 Instruction Set

SUSE Linux Enterprise Server for the Raspberry Pi is the first commercial distribution for the

Raspberry Pi using the ARM 64-bit AArch64 instruction set.

Boot Process

In Raspbian, the kernel is loaded directly. This is not supported by SUSE Linux Enterprise Server

for the Raspberry Pi, where the U-Boot boot loader is used to provide an EFI boot environment. A

GRUB2 EFI binary is chain loaded to provide a graphical boot screen.

Root Filesystem

SUSE Linux Enterprise Server for the Raspberry Pi uses btrfs as the file system for the root

partition. Compression is enabled by default for better SD-Card performance.
