Can you relate?

A common day in the life of a developer

My Code

6

Operations is slow and long on their delivery with unpredictable delivery dates. No one is responsible for the delivery requirements and there is a total lack of communication.

I just like to see Green!

Enter DevOps

The DevOps Way

Typical Paradigms

Imaging / Packaging / Patching / Upgrades:

‒ Development standards often ignored – no enforcement

‒ Difficulties decoupling middleware/application upgrades from OS-related upgrades

‒ Building new images for new OS versions is usually approached by building and re-building from scratch

‒ This typically requires project initiation and implementation every time, with significant overhead costs.

The SUSE Approach

The SUSE Approach…

Software Und Systeme Entwicklung

“Software & Systems Development”

The SUSE Approach…

SUSE is more than just a Linux distribution!

The SUSE Approach…

SUSE design principles:

- Open Source & Open Development- APIs- Standards Based (protocols, languages, etc)- Enterprise Focus

Efficiency – Deployment Options

System Inspection “Machinery”

Various Output Format

Ahhhhhh...

Concept Leverage these components for developing, building, testing, integrating and managing hosts :

PACKAGE :Open Build Service - www.openbuildservice.org

BUILD :Kiwi/SUSE Studio - www.susestudio.com

TEST :openQA - openqa.opensuse.org/

DEPLOY : Virtual Workloads via SUSE OpenStack Cloud, VMware ESX, Cisco UCS, other image deployment mechanisms www.suse.com/products/suse-cloud/

MANAGE/MONITOR:SUSE Manager, Nagios www.suse.com/products/suse-manager/

SUSE (and other) Tools

SUSE ComponentsPACKAGE :Open Build Service

• Web Client and a CLI (osc)

• Allows for simple package creation

• Upload sources with wget or via web client

• Import or copy source packages

• Add repositories

• Build packages locally or on source server

• Reporting

• Collaboration via branching/merging/review/commit - request tracking

• Version testing

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

Kiwi

• 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

• Very flexible

• With flexibility comes complexity

How do I build it?The easy way ...

SUSE Studio

Two ways to get it:1. SUSE Studio Onsite

https://www.suse.com/products/susestudio/

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

Provides a simplified, web-based user interface for Kiwi

Use Cases

Virtualization/Containers

Embedded Systems

Cloud

Modules: An Easier Way to Get New Enhancements

Easier access to the latest updates

Different lifecycles, ranging from continuous integration to three years

Fully maintained and supported

Included in subscription without additional cost

Modules: A Closer Look

Module Name Content Lifecycle

Web and Scripting Module

PHP, Python, Ruby on Rails 3 years, 18 months overlap

Legacy Module Sendmail, old IMAP stack, old Java, etc.

3 years

Public Cloud Module Public cloud initialization code and tools

Continuous integration

Toolchain Module GCC Yearly delivery

Advanced Systems Management Module

cfengine, puppet and the new machinery tool

Continuous integration

Containers Module Docker Continuous integration

How is it different?

Docker• Supported as of June 2015

• Runtime and infrastructure to create SLE Docker images

• YaST interface for Docker

Benefits using Docker• Fast: performance = bare metal speed

• Flexible: put a system or application into a container

• Ship Docker images, not VMs

Better integration and management of Containers• Uses libvirt-lxc framework

• Same management layer as KVM and XEN

• Allows for integration with SUSE® Manager and SUSE OpenStack Cloud

• Unified tooling, independent of the “virtualization” mechanism

SELinux and AppArmor support and LXC

Filesystem copy-on-write (btrfs integration)
