GuideIntroduction
The DTGov project layers Design Time Governance functionality on top of an S-RAMP repository. These two projects work together to provide the following:
-
Store and Govern artifacts
-
Custom Governance Workflows
-
Integrated Governance Human Task Management
This guide will discuss the various pieces of functionality provided by DTGov and how to configure and use them.
In addition to a general framework for triggering business workflows based on changes to artifacts in the S-RAMP repository, the DTGov project focuses on the following specific Governance Use Cases:
-
Deployment Lifecycle Management
This guide will not only discuss the generic governance capabilities provided by the DTGov project, but also the specific Use-Cases listed above.
-
Workflows are created from JBoss jBPM (BPMN2) process definitions.
-
A version of jBPM is embedded in the deployed dtgov.war. This version of jBPM is configured to use the S-RAMP repository as the source for workflow definitions.
-
To use a workflow with DTGov, the jBPM workflow files must be bundled into a Jar file named "dtgov-workflows.jar" and uploaded to the DTGov S-RAMP repository. There are several methods than can be used to deploy the workflow jar file to S-RAMP. We recommend that you use maven.
-
The embedded jBPM pulls the dtgov-workflow.jar out of S-RAMP at runtime and uses the workflow definitions found therein.
-
In this context, "runtime" refers to whenever a new workflow instance is created (typically triggered by an artifact being added or changed in the s-ramp repository).
-
Any human tasks that are used in any DTGov workflow will appear in the Tasks UI included in the DTGov UI (http://localhost:8080/dtgov-ui)
-
A workflow deployment only shows up in the dtgov-ui/#deployments page once a lifecycle management jBPM process is kicked off for it.
-
A sample Process Workflow ("SimpleReleaseProcess") is packaged with DTGov
-
OOTB SimpleReleaseProcess does "Lifecycle Management" governance on an artifact by monitoring the S-RAMP repository periodically (60 sec default) - this monitoring takes the form of a query on the repository.
-
When an artifact matches that S-RAMP query as configured in the DTGov config file (dtgov.properties) which is mapped to the SimpleReleaseProcess a new jBPM process instance is created for that artifact. The process can do anything it wants at that point.
