Deployment von Java Web Applikationen mit Chef von Opscode

There is a rework of the data driven deployment of java web applications. This Vagrant project on github ( https://github.com/iteh/vagrant-demos/ ) showcases the application cookbook for chef with a reworked application definition and LWRP for Tomcat.

Data Driven Java Application Deployment got better

The application cookbook helps to install a full application stack for java web applications. It abstracts the installation of apache, tomcat and mysql to be modeled through a data driven concept. In this rework we add a tomcat_context LWRP and move the application recipes to definitions.

Now we can use something like this:
app = JSON.parse(File.open( File.join( File.dirname(__FILE__), \ "../databags/jolokia.json")).read)

node.run_state[:current_app] = app

application_java_webapp “jolokia-java_webapp”
application_tomcat “jolokia-tomcat”

node.run_state.delete(:current_app)

The configuration is still the same and can be found in databags/apps/java_app.json. It defines the server name and alias, the war and container context as well as the database to use.

Run it

Download the archive or to a git clone. Ensure that you have a proper Vagrant environment installed. Change to the “vagrant-java-application-reworked” directory and enter

$ vagrant up

This will download the lucid32 box (500 MB so this can take a while on the first download) and do the provisioning

after the chef-solo run you can access http://java_app.smackaho.st:4567/probe/ with the username “probe” and the password “probe” this hits the application through apache. http://java_app.smackaho.st:4568/probe/ will hit tomcat directly.

To prove the jdbc connection go to http://java_app.smackaho.st:4567/probe/sql/datasourcetest.htm?webapp=/probe&resource=jdbc/java_app
