The DCM Maintenance App supports multi-tenancy for communication with the Case Engine, it's data sources and asynchronous messaging.

Enabling multi-tenancy

To enable multi-tenancy, the following properties should be provided in the configuration:

Code Block
languageyml
titleblueriq-dcm-maintenance-app.yml
blueriq:
  multi-tenancy:
    enabled: true
    allowed-tenants:
      - A
      - B
Excerpt

Authentication

To be able to use the DCM Maintenance App, the user should be authenticated. This is done through Keycloak as explained in Blueriq Gateway and OAuth2 configuration. The difference with multi-tenancy is that the application now expects a claim to be present in the JWT token with the claim path name "tenant" and with the tenant name as value. This claim name is customizable if the tenant is present in the JWT token with a different claim name.

Customizing the tenant path

The tenant claim can be customized using a JsonPath expression in the same way the roles-path and username-path can be set.

Code Block
languageyml
titleblueriq-dcm-maintenance-app.yml
blueriq:
  jwt:
    tenant-path: $.custom_tenant_claim_path

RabbitMQ and MongoDB configuration

For RabbitMQ and MongoDB the properties need to be set per tenant as well.

Currently, it's required to supply the queue and exchange names if multi-tenancy is enabled. This is an example of this configuration:


Code Block
languageyml
titleblueriq-dcm-maintenance-app.yml
blueriq:
  multi-tenancy:
    enabled: true
    allowed-tenants:
      - A
      - B

            max-retries: 3
