MariaDB & SUSE

3

SUSE Linux Enterprise Server ships MariaDB

4

SUSE Software Catalog: MariaDB

● MariaDB is listed in SUSE's Software Catalogwww.suse.com/isvcatalog

● MariaDB 10 is certified for SLES 11 and 12

5

MariaDB on Open Build Service

● Find projects that already build newer versions of MariaDB for SLES 12

● Build bleeding edge versions for SLES

● OBS Packages are without support!

● build.opensuse.org

https://build.opensuse.org/

6

MariaDB on SUSE Studio

● Creating Software Appliances

● Use OBS repositories● Several Formats

available:● Preload (usb, iso)● Live CD● VM (vmdk, ovf, img, qcow2)● Cloud (ami, vhd)

MariaDB & SUSE Manager

8

Manage the Full Life-Cycle with SUSE Manager

9

Deploy & Manage MariaDB with SUSE Manager

● Provisioning new machines with autoinstallation● Centralize Packages Management incl. MariaDB● Build and Manage software stagings for controlled operations of

Development, Testing & Production landscapes● Rollout configuration of MariaDB settings● Monitor configuration changes

10

Provision New MachinesDifferent Levels of Automation

● Without PXE● Kickoff installation with boot iso● Select autoinstall profile● Answer individualization questions during installation● (Move new system after installation to MariaDB group)

● With PXE● Kickoff PXE boot● Select autoinstall● Answer individualization questions during installation● (Move new system after installation to MariaDB group)

11

Provision New MachinesDifferent Levels of Automation

● With PXE and SUSE Manager Discovery● Kickoff PXE boot● Select System in SUSE Manager for Deployment● Provide all required individualization by variables● Start Machine

12

Installation Example – Step 1

● Prerequisits:● Distribution● Installation Profile

● Task:● Boot via PXE● Select Profile to Install

13


● Prerequisits● Ask Section in Autoprofile● Default values (script or listing)

● Task● Fill in or select required values

14


● Prerequisits● None if setup is fine :)

● Task● Waiting :)

15

Installation Example – Finish

● Complete Automation● Keys, Roles, Grains,

States made your system ready to go

● Best Effort Automation● General OS deployed● Roles, Grains, States

manually assigned by moving system into a group

SUSE Manager 3

States

Description of how a system configuration• YAML

• Jinja2 Templating

• Uses Salt State Modules

Salt States Catalog• SUSE Manager provides an integrated, central store for own states definitions

– Assignable to SUSE Manager Organization, Group, Systems

• Optional you can store an own structure of states within /srv/salt forusing non-integrated Salt Features

SUSE Manager 3 – Salt Basics

Typical Statefile Structure

19


Example State

install_mariadb: pkg.installed: - name: mariadb

service_mariadb: service.running: - name: mysql - enable: True

config_files_mycnf: file.managed: - name: /etc/my.cnf - source: salt://my.cnf - user: root - group: root - mode: 640

20


State Dependencies

Requisit declarations define dependency/order of single state statements:● Require● Watch● Onchanges● Prereq● Onfail● Use

21


Example State

[...]

service_mariadb: service.running: - name: mysql - enable: True - watch: - pkg: mariadb - file: /etc/my.cnf

[...]

SUSE Manager 3

Salt Elements Beyond States

Beacons• Monitor for changes/thresholds and send events in case

Reactors• Execute “run books” on specific events

Orchestration• Manage relations/actions between servers up to firing complete setups in private

or public clouds

Proxy• Use minioncontroller to manage devices that are not capable to host agent

(python etc.)

25

Use Case: Monitor Configfile for Changes

Change Event Received

salt/beacon/mymariadb.bo2go.home/inotify//etc/my.cnf {

"_stamp": "2016-11-28T19:37:15.317124",

MariaDB in Docker with SUSE

27

Deliver MariaDB in Docker Containers

SLES12 supports docker:● Images from trusted source (repository)● Full control over your data: on-premise registry,

authentication ● Pre-built SLES Docker images

SUSE provides built-in tools:● YaST interface● sle2docker, zypper-docker● Portus
