14. Add a Cron Job
15. #!/bin/bash -ex export PATH=$PATH:/usr/bin:/usr/local/bin drush -r /Users/andrew/Documents/workspace/ drupal7 core-cron It’s a Shell Script!
16. Notifications ‣ Email ‣ Jabber ‣ Twitter ‣ IRC ‣ Notifio ‣ SMS Gateways ‣ More!
17. Other Jobs ‣ Run SimpleTest, or Selenium ‣ Pull in remote repositories into a vendor repository ‣ Verify the status of files in production ‣ “Test and Tag” ‣ Let’s take a look at drupal.org’s Hudson instance
18. Jenkins Best Practices ‣ Keep your shell scripts short ‣ Pull in scripts into your workspace via VCS or the execute shell command ‣ Write your scripts in bash, perl, PHP, VBScript ‣ Write Drupal-specific commands as Drush commands so developers can trigger them
19. ‣ Not all jobs need to be automatic ‣ Jenkins is a great way to train up junior sysadmins or developers ‣ Discoverable, clickable, scriptable ‣ Watch your build history ‣ Be careful about the archiving of artifacts and workspaces
