- : devicemanager + internal WEB Server
- SDNRDM: devicemanager relateded bundles, but not web related
- SDNRINIT: Only database initialization than terminating. See: SDN-R Data Migration Tool
- SDNRONLY: Do only start SDN-R related bundles, remove all other bundles from featureboot list.
Database configuration by SDNRDBURL, SDNRDBUSERNAME, SDNRDBPASSWORD.
| SDNRWT | SDNRDM | SDNRINIT | Meaning |
|---|---|---|---|
| false | x | x | (Default setting of flags). SDNR deactivated, but normal SDNC startup for other features, like oofpci. |
| true | false | false | devicemanager + internal WEB Server. SDNRDBURL, SDNRDBUSERNAME, SDNRDBPASSWORD |
| true | true | false | devicemanager. SDNRDBURL, SDNRDBUSERNAME, SDNRDBPASSWORD |
| false | x | true | init container function. SDNRDBURL, SDNRDBUSERNAME, SDNRDBPASSWORD. Exit after configuration is done. |
| true | true|false | true | execute init function and start ODL according to description |
x: do not care
Initialization scripts
SDNC/OAM Container entrypoint: /opt/sdnc/bin/startODL.sh
The duplicated script should be removed from OOM. Issue for this is:

Environment Variables and configuration files
The startup env parameters are used by properties of configuration files
| env var | config file $ODL_HOME/etc/ | description |
|---|---|---|
| SDNRDBURL | dataprovider.properties | (mandatory) elasticsearch URL |
| SDNRDBUSERNAME | dataprovider.properties | (optional) elasticsearch basicAuth Username |
| SDNRDBPASSWORD | dataprovider.properties | (optional) elasticsearch basicAuth Password |
Database Initialization
ElasticSearch database needs to be initialized by a script.
bin/es-init.sh
OOM enhancement: define kubernetes Job to execute e-init.sh
Development steps
Enhancement/integration of oom/sdnc follows from left (low complexity) to right (highest complexity)
Step 1: SDNRWT SDNRDM enabled
- introduce config switch (see
