About GerritForge
Founded in 2009 in London UK
Mission:
Integrate Gerrit with
the Enterprise

4. 4
Agenda
 Gerrit community is growing
 Why going native?
 Native binaries
 Docker distribution
 Installing a Gerrit plugin in 1 second!
 The Certified choice

5. 5
Gerrit 4 years ago
We could all fit in
medium class-room

6. 6
Gerrit in 2015
… something like this

7. 7
Gerrit at the beginning
 All-in-one monolithic WAR
 One file drop + init set-up
 Limited but simple configuration
 Mainly used by its developers / contributors
 Maven-based (very slow) build
 No plugins

8. 8
Gerrit today in numbers
 Over 1.1M lines of code
 Fully modular and extensible
 Web, TTY, IntelliJ / Eclipse user interfaces
 56 plugins and growing
 Users have little knowledge of Gerrit internals
 BUCK-powered (super-cool and fast) build

9. 9
Hold on, WAR set-up
wizard is quite easy
WHY on earth do we
need another
packaging?

10. 10
General growth challenges
 Gerrit community gets diverse
 Non-java developers are using Gerrit
 Lower % of Gerrit users can understand and
change the source
 Companies may not have access to BUCK in their
build systems

11. 11
Enterprise challenges
 Gerrit managed by non-devs
 More general "tools Opts" rather than gurus
 Company standards in Software distribution and
updates
 Need of standard Enterprise Support tools

12. 12
Filling the gap
Step #1

13. 13
Let's install Gerrit as any other sw package
$ apt-get install gerrit
$ /etc/init.d/gerrit start
$ tail –f /var/log/gerrit/error_log
 Does not require Gerrit-specific skills
 Can be easily automated
 Can be controlled / integrated with standard Sw
management tools
 Packages can be signed and certified

14. 14
Filling the gap
Step #2

15. 15
What about Gerrit pre-installed?
$ docker pull gerritforge/gerrit-centos7
$ docker run –d -p 8080:8080 gerritforge/gerrit-centos7
Gerrit in a Docker container?
• "one-click" away from Amazon
Cloud
• Baseline for customized configs
• Allows smoother migration thanks
to versioned VMs

16. 16
When can I start using them?
Gerrit 2.10 and 2.11 distributed as
RPM, DEB and Docker

17. 17
Wow, how many people used them?
Docker pulls overall:
531 of CentOS 7-based
2,400 of Ubuntu-based
Native packages downloads/month:
189 RPMs
109 Debs downloads

18. 18
What about Gerrit configuration?
 RPMs and Debs contain a playground-style
config
 Still lots of Gerrit skills needed to configure /
customize it

19. 19
GerritForge certified distribution
 Template-based configuration for common
scenarios:
oActive Directory
oLDAP
oJira Integration and SSO
oIBM Rational Team Concert Integration
oGerrit with GitHub:Enterprise
o…

20. 20
One plugin to
manage them all
Step #3

21. 21
What about Gerrit plugins?
 Plugins aren't part of Gerrit WAR (apart from 6 core
plugins)
 Different plugins = different maintainers
 Plugins supported / compatible vs. Gerrit versions
 Different plugins = different build systems
(BUCK, Maven, Sbt)
 Plugins hosted on different repositories
(Gerrit-Review, GitHub, my-own-git.com, …)

22. 22
Plugin-Manager = the lord of the plugins
 Why don't we have only ONE plugin pre-installed?
o Discover new plugins
o Compatibility check: plugin Version vs. Gerrit
o One-click plugin install

23. 23
Discover and install plugins in 1 sec

24. 24
Introducing GerritCentral.com
 More plugins / Gerrit builds and compatibility
 Consistency during Gerrit migrations
 GerritForge-signed and verified build
 Built, loaded and smoke-tested
 Option to get Enterprise Support coverage
