3. Rails Apache Apache Apache Apache Passenger

4. * Ruby on Rails /app /config /db /doc /lib /log /public /script /test /tmp /vendor config.ru README Rakefile

5. run updated script App Server App Server Pull Pull Git 1 2 3 signal over SSH Local Repository contains all scripts

6. SCM-aware deployments fast and effortless dev and deployment on ruby transfers only delta devenv mess can overflow admin-hell for IT/Ops compiling native gems

7. Git Pull CI Runs Tests Tests Code $ deploy 77ef185d7 $ deploy 77ef185d7 QA Prod. Staging

9. CI Runs Tests

10. Git Pull Unit Tests CI Perf Tests Functional Tests

11. Git Pull Unit Tests CI Functional Tests Push a Tag tag: mainline-234 Perf Tests

12. Git Pull Unit Tests CI Functional Tests Perf Tests

13. Git CI mainline unit tests func tests perf tests

14. mainline unit tests func tests perf tests 1 2 3 tag Git on remote machine on CI machine deploy emit consume package

15. RPM mainline unit tests func tests perf tests tarball war 2 1 tag Git rubygem deb 3 on remote machine on CI machine deploy emit package consume

16. tarball better than a directory extremely simple to setup no metadata

17. RPM, deb stored in a repository standard locations -- /etc first-class system service effected by chef/puppet toolchain expertise maintain a repository less common

18. rubygem tarball with metadata effected by chef/puppet stored in a repository maintain a gem repository

19. mainline unit tests func tests perf tests upload to a repo 2 expose over CI artifact API 1 tag Git 3 on remote machine on CI machine deploy emit package consume

20. mainline unit tests func tests perf tests 2 1 tag Git 3 on remote machine on CI machine deploy emit package consume

21. Config Management gem install yum install apt-get install

22. /etc my.cnf httpd.conf ssh_config

23. /etc database.yml .htaccess private keys for external systems

24. /etc/myapp First Class Linux Application Software

25. bundle install --deployment install to vendor/bundle bundle install --without test development bundle package .gem files to vendor/cache bundle install --local
