WSO2 Application Server (AS) 5.2.1 is provided as a service on WSO2 Private PaaS 4.1.0. This is implemented by creating a template module, a cartridge agent plugin, a Docker image and a Puppet module. The template module is used for configuring the product in runtime with a set of key value pairs (configuration parameters). The cartridge agent plugin is used for setting the runtime configuration parameters such as hostnames, IP addresses of dependent clusters, dynamic proxy ports, etc. The Docker image is built by packaging the cartridge agent, configurator, template module, product distribution and the Java runtime.The puppet module will also include the same set of component as in the Docker image and the template module will be used for the configuration automation.
