mta.yaml files you can use the
service-name parameter to point to an existing service instance with a different name than the resource.
When the contents of a multi-target application file file have been created or modified automatically for you, and there are references to generated service instance names, you don't have to globally replace those names to match whatever service instances you may already have, but instead you can add the
service-name parameter in the resource definition.
For example, when adding a new Workflow module to an existing (
mta.yaml-based) project, the generator will add something like this:
modules: - name: OrderProcess type: com.sap.application.content path: OrderProcess requires: - name: workflow_mta parameters: content-target: true resources: - name: workflow_mta parameters: service-plan: standard service: workflow type: org.cloudfoundry.managed-service
It's often the case that you already have a Workflow service instance, but not with the generated name
workflow_mta. So after modifying the resource
type to be
org.cloudfoundry.existing-service, you can save some time and avoid changing all occurrences of
workflow_mta to match your actual instance name (e.g.
my-workflow-instance). Instead, use the
service-name parameter, like this:
modules: - name: OrderProcess type: com.sap.application.content path: OrderProcess requires: - name: workflow_mta parameters: content-target: true resources: - name: workflow_mta parameters: service-name: my-workflow-instance type: org.cloudfoundry.existing-service
I learned this a while ago but promptly forgot about it until now, when I needed it again.
