    The puppet module includes the same set of component as in the Docker image. In the puppet image the template module is used to configure automation.

 

Deploying WSO2 API Manager as a Service

Deploy WSO2 API Manager as a service using one of the following methods. 

Note

Make sure that you note the points given below:

  • The server shut down timeout can be changed by defining a new value under property in the cartridge definition.
    Example:

    Code Block
    name : CONFIG_PARAM_SERVER_SHUTDOWN_TIMEOUT value : 120

    The value should be specified in seconds. In the above example the value is defined as 120 seconds.

  • Sign up for the API Manager application in Private Paas by giving the specific Git repository URL, for both the gateway manager and gateway worker cartridges. This is required for artifact distribution.
     

  • Make sure that you note the points given below when running WSO2 Identity Server as a Key Manager:

    • Use the pre packaged Identity Server pack that is specifically designed to run as the Key Manager. Do not use the default IS pack. 

    • Rename the patch0012 kernal patch to patch9999 if you are applying the WSO2 Identity Server Service Pack for 5.0.0. This is done to support Private PaaS membership schema which comes from then kernal patch 12.

 

Deployment Architecture

The deployment architecture is designed to support different deployment patterns of API manager, within the the API manager application. It consists of two cartridge groups as shown below:

...

In the above deployment, five different Private PaaS clusters are created for the gateway manager, gateway worker, key manager, store and publisher. These clusters can be scaled independently. However there will be Carbon clusters created across different Private PaaS clusters. The gateway manager and gateway worker will connect to one Carbon cluster, the store and publisher will connect to another Carbon cluster and the key manager will have a separate Carbon cluster.

Template Module

The WSO2 AM 1.9.0 and 1.9.1 template module provides a set of templates that is used to configure the API Manager with the Configurator.

Info

You can find the WSO2 AM 1.9.0 template module here and the 1.9.1 template module here.

 

Cartridge Agent Plugin
