elm-sync configuration is done in the Spring Boot application.yml file. The configuration associates one CDCM space with one or more ELM GCM serverservers, and lists the CDCM Configuration Areas that should be synchronized with ELM GCM. Configuration includes the following topics:
The elm-sync server configurationThe
spring application configuration including
security for oauth2 for CDCM access
SQLite database configuration for elm-sync
cdcm sever and API
ibm-elm server and API information
spring security for oauth2 for CDCM access
OAuth1.0a configuration for access to ELM GCM
The cdcm Configuration Area to ELM GCM server mappings
...
elm-sync uses the configuration information in the application.yml file to configure the CDCM and ELM GCM server URLs, access control and API information, and the list of CDCM Configuration Areas to sync. elm-sync then uses the CDCM TRS provider to read the change long log to replicate changes in CDCM in the corresponding project areas and resources in ELM GCM. elm-sync does not use the CDCM TRS base to determine what configuration areas to sync. Rather these the CDCM Configuration Areas to sync are explicitly defined in the configuration.area.mapping elements.
elm-sync also does not currently use the trs:cutoffEvent, assuming as it is always 0. This effectively means elm-sync assumes the TRS base is empty and all the TRS provider information is in the change log. This may need to be updated if when CDCM implements change log pruning.
...
The application.yml
defines various information elm-sync uses to determine what CDCM configuration areas should be synced to ELM GCM and how to access them through their authenticated APIs. Here’s an example application.yml file.

elm-sync server configuration
This section defines the elm-server configuration including the server port and context-path for accessing the elm-sync controllers, and server instance information.

CDCM OAuth2.0 security information
An SQLite database for persisting information about the CDCM configuration areas and ELM GCM project areas that are being synchronized.
Access to CDCM uses AOuth 2 which is configured for the Spring Boot application using the cdcm-client. Your CDCM administrator can provide your client-id and client-secret, and information on the provider.cdcm-client that does the authentication.
The database information includes:
The Configuration Area id
The ELM Server URL and corresponding project area URL
The trs:order number of the last trs:change event processed by elm-sync. Changes after this event will be processed on the next elm-sync scan cycle.

ELM GCM OAuth1.0a Security Configuration
elm-sync uses OAuth1.0a to access ELM GCM through the REST APIs. This access is done through a functional user whose ID is associated with a consumer key and secret.

pa-get-path: /gc/service/com.ibm.team.process.internal.service.web.IProcessWebUIService/allProjectAreas
config-update-path: /gc/gc.webui.updateConfiguration
|
Future considerations:
The pa-creation-path, pa-get-path and config-update-path are specified in ELM GCM private API. These paths are unlikely to change or could possibly be discovered and may not need to be configured manually. See https://jazz.net/gc/doc/scenarios.
The ibm-elm.api.host property limits elm-sync to syncing a single CDCM space to a single ELM GCM server. This will be updated to support multiple ELM GCM servers and this property will be removed, instead getting the value from the configuration.area.mapping.target value.
ELM GCM OAuth1.0a Security Configuration
elm-sync uses OAuth1.0a to access ELM GCM through the REST APIs. This access is done through a functional user whose ID is associated with a consumer key and secret.

The outbound.details provide the information elm-sync need to be able to access ELM GCM services using OAuth1.0a for authentication.
The smartfacts.oauth10a.inbound.relm-name is required, but not currentluy used. It is included for future use.
Creating the ELM GCM functional id
elm-sync access the ELM GCM REST APIs using OAuth1.0a and a functional id. The is the most reliable way to do server to server communication with ELM servers because they all use OAuth1.0a to configure consumer/friend relationships to allow the ELM servers to talk to each other. OAuth1.0a can be reliably depended on to be supported by ELM servers.
For elm-sync to access ELM GCM, you must register elm-sync with the ELM Jazz Team Server (JTS) as a consumer (inbound) connection, with consumer key and secret. Then you need to associate that consumer with a functional id that has JazzAdmins, JazzUsers and JazzProjectAdmins repository permissions. Here a brief summary of the steps
Navigate to the Jazz Team Server Administration Home page
Manage or create users and create the functional id with JazzAdmins, JazzUsers and JazzProjectAdmins repository permissions
Click Manage Server and then Communication > Consumers (Inbound)
Use the Register Consumer form to create a Trusted Consumer Key with a Consumer Secret. This is the same information that will be used in the smartfacts.oauth10a.outbound.details entry in the application.yml file.
Edit the newly created Authorized Key and set the Functional User ID to the Id you create above:

The inbound.relm-name is used for the elm-sync REST API services defined in the com.mid.smartfacts.cdcm.elmc.controllers classes:
ElmApplicationController: provides rootservices, service provider catalog and about information for elm-sync
TestConfigurationAreaReaderController: implements various fixed test cases for accessing CDCM Configuration Areas
TestController: implements various test cases for accessing CDCM and ELM GCM resources, useful for developing automate test cases and for exploring implementation options and issues

CDCM Configuration Area to ELM GCM Server Mappings
Note: Although a configuration.area.mapping.target specifies the URL of the ELM GCM server, this URL must be the same as ibm-elm.api.host. elm-sync is currently configured to sync one CDCM server with one ELM GCM server. A different instance of elm-sync could be used to sync different CDCM and ELM GCM servers.
Future consideration: Support configuration of multiple CDCM and ELM GCM servers in a single elm-sync implementation:
Change configuration.area.mapping.source to a URL link to the CDCM configuration area, instead of just its ID
Derive the ibm-elm.api information for the configuration.area.mapping.target URL through discovery
Configuration
elm-sync is configured using the Spring Boot project file application.yml
. This file has to be put in the application’s resources folder. Spring Boot profiles can be used for different configurations such as application-local.yml
for local development, and application-prod.yml
for production.
Kubernetes
The application.yml
contains security sensitive information such as consumer keys and secrets, and should be placed into a kubernetes secret, and mounted into the CDCM container. The name of this secret is "elm-sync", the value of is the application.yml
file.
To integrate the application.yml file into your CDCM deployment, you need to create a secret called “elm-sync” in the namespace of your CDCM deployment.
There are two ways to do this:
Use
kubectl
Code Block |
---|
kubectl create secret generic elm-sync --from-file=application.yml=./resources/application.yml -n cdcm |
If the secret has to be created manually or from a vault, use this template:
Code Block |
---|
apiVersion: v1
data:
application.yml: <base64 encoded content of the file application.yml>
kind: Secret
metadata:

Save the file as application.yml
and apply it with:
Code Block |

kubectl apply -f application.yml -n <namespace> |
