Deploying Apache Tomcat Applications With Puppet

Deploying Apache Tomcat Applications With Puppet | TomcatExpert April 29, 2010 11:34 AM

• Deployment of Java applications are difficult, and they need Java specific management tools. 
• One tool should be sufficient and can make everyone's life easier.
• Puppet. 
• Cross-platform, 
• Works on most Linux and Unix based operating systems (including OS X), 
• Will be taking on Windows support in the near future. 
• A model driven solution that requires no coding knowledge to use. 
• Example:
• If I want to create a user, do I need to know the differences between user creation on OS X and Linux? Not really, 
• I'd just like to specify the attributes and share the same deployment instructions. 
• Puppet helps you do this.

Patrick Debois's Tips

• Tip 1 : give each module it's own repo and use a superproject to join
• Using Git
• Using Mercurial 
• Workflow
• Less scary: no way to wrongly add directories
• It's handy that you can add both svn, git and hg subrepositories
• Submodules are checked out by default (no git submodules init, update)
• Note
• by default hg wants to commit to all subrepos when commiting to the super-project repo. This Recursive commits can be disabled with the local ui.commitsubrepos¨ configuration setting introduced in Mercurial 1.8.
• More information on Mercurial subrepositories can be found at: http://mercurial.selenic.com/wiki/Subrepository?action=show&redirect=subrepos#Synchronizing_in_subrepositories
