This document discusses best practices for continuous deployment of software projects. It outlines five rules: 1) implement deployment from the beginning, 2) automate everything using tools like Puppet, 3) test quality using tools like Jenkins, 4) create reusable deployable artifacts, and 5) run deployments with a single command using tools like Fabric. Specific techniques are recommended, like using Ant build files, promoting builds through stages like testing and staging, storing artifacts in S3, and keeping deployment configurations with code. The goal is to enable continuous integration and deployment of changes to production with minimal manual steps.

Ate My Deployment

8. Rule 1:
Implement deployment at the
beginning of your project

10. Every configuration has to be
done by Puppet

11. Developers and Operations
share the same configuration

12. Rule 2:
Automate everything

15. Create Targets
For Everything

16. Structure Your
Ant Files

17. Use A Framework For This

18. <project>
<property file="default.properties"/>
<import>
<fileset dir="${basedir}/extensions">
<include name="*.xml"/>
</fileset>
</import>
<extension-point name="build-cleanup" />
<extension-point name="build-prepare" />
<target name="build:ci" depends="
test:run, package:create" />
</project>

19. $ ant quality:report

20. Rule 3:
Test the quality of your
project

22. Jenkins PHP Template

23. PHP QA Tools

24. Too many violations should
break your builds

25. Rule 4:
Create deployable artifacts

26. Build them so that they only
need configuration to run

27. Create them once, reuse
them in all deployments

28. Copy Artifacts
Build Promotion
Amazon S3

29. Continous
Integration
Testing Staging Live

30. Rule 5:
Run your deployment with
only one invocation

32. Choose Your
Deployment Tool

33. Choose It
With Your Operations Team

34. Shell Scripts

36. Choose A Tool
That Helps You

37. Fabric

38. def deploy(docroot):
put('release.tar.gz', 'release_dir')
run('tar xzf release.tar.gz')
with cd(release_dir):
run('ant symfony:cache-clear')
sudo('service nginx restart')

39. Keep Your Deployment
Configuration With Your Code

40. $ fab deploy:/var/www –H host1,host2,host3
