What is Context Handler?

The Context Handler API is a RESTful web service component of Consent2Share (C2S). It is responsible for sending XACML response context that includes authorization decisions along with applied policy obligations to Policy Enforcement Point (PEP) API components. The Context Handler sends the XACML request context to the Policy Decision Point (PDP). The PDP evaluates the applicable policies from the Patient Consent Management (PCM) against the request context, and returns the response context that includes authorization decisions along with obligations of applied policies to the Context Handler. The Context Handler sends XACML response context back to PEP component. The PDP uses HERAS-AF, an open source XACML 2.0 implementation, for XACML evaluation and uses a PCM database as a local policy repository to retrieve XACML policies that are generated from patients’ consents.

How to use this image

Start a Context Handler instance

Be sure to familiarize yourself with the repository's README.md file before starting the instance.

docker run --name context-handler -d bhits/context-handler:latest <additional program arguments>

NOTE: In order for this API to fully function as a microservice in the Consent2Share application, it is required to setup the dependency microservices and the support level infrastructure. Please refer to the Consent2Share Deployment Guide in the corresponding Consent2Share release (see Consent2Share Releases Page) for instructions to setup the Consent2Share infrastructure.

Configure

The Spring profiles application-default and docker are activated by default when building images.

This API can run with the default configuration which is from three places: bootstrap.yml, application.yml, and the data which the Configuration Server reads from the Configuration Data Git Repository. Both bootstrap.yml and application.yml files are located in the class path of the running application.

We recommend overriding the configuration as needed in the Configuration Data Git Repository, which is used by the Configuration Server.

Also, Spring Boot supports other ways to override the default configuration to configure the API for a certain deployment environment.

The following is an example to override the default database password:

docker run -d bhits/context-handler:latest --spring.datasource.password=strongpassword
