This will generate some code from the yang models. +* Modify the model yang file under the model project. +* Follow the comments in the generated provider class to wire your new provider into the generated +code. +* Modify the generated provider model to respond to and handle the yang model. Depending on what +you added to your model you may need to inherit additional interfaces or make other changes to +the provider model. + +Generated Bundles +====================== +* model + - Provides the yang model for your application. This is your primary northbound interface. +* provider + - Provides a template implementation for a provider to respond to your yang model. +* features + - Defines a karaf feature. If you add dependencies on third-party bundles then you will need to + modify the features.xml to list out the dependencies. +* installer + - Bundles all of the jars and third party dependencies (minus ODL dependencies) into a single + .zip file. + +Usage +====================== +## Purpose +The purpose of this ODL feature is to support local and geo-redundancy by providing a way to +back up and retrieve MD-SAL data exports to and from a Sonatype Nexus server. In order to function, +this module requires the controller to have an installation of the ```data-export-import``` module and a valid export of MD-SAL data. + +## Backup +MD-SAL Backup can be achieved using the ```daexim-offsite-backup:backup-data``` RPC either through the +RESTConf portal or through a tool such as cURL or Postman. While no input is required for this RPC, +the RPC does require the operational, models, and config .JSONs to be present in the daexim directory of the controller. +```sh +export USER=user +export PASSWORD=password +export ODL_HOST=https://yourhost.com:8181 +curl -X POST -u$USER:$PASSWORD ${ODL_HOST}/restconf/operations/daexim-offsite-backup:backup-data +``` +Through this process a timestamped archive is created in the form of ```POD_NAME-yyyyMMdd_HH-odl_backup.zip``` +where ```POD_NAME``` is the name of the ODL, specified through the properties file or through an environment variable. + +## Retrieval +MD-SAL Retrieval can be achieved by using the ```daexim-offsite-backup:retrieve-data``` RPC either through the +RESTConf portal or through a tool such as cURL or Postman. This RPC requires timestamp information and may +be supplied with an optional podName. + +```sh +export USER=user +export PASSWORD=password +export ODL_HOST=https://yourhost.com:8181 +export TARGET_ODL=targetOdlPodName +export TIMESTAMP=yyyyMMdd_HH +export DATA= ' + { + "input": { + "pod-name": "'"$TARGET_ODL"'", + "timestamp": "'"$TIMESTAMP"'" + } + }' +curl -X POST -u$USER:$PASSWORD --data $DATA ${ODL_HOST}/restconf/operations/daexim-offsite-backup:retrieve-data +``` + +Through this process an archive with the specified timestamp (and optional pod name) is downloaded from +the Nexus server and extracted into the controller's daexim directory. After this it is up to the user +to trigger an MD-SAL import. + +## Properties File +Before each RPC execution this module pulls information from a user supplied properties file. The module expects to find: +- daeximDirectory +- credentials +- nexusUrl +- podName +- file.operational +- file.models +- file.config + +> Refer to the example properties file + +If the module cannot find the properties file it will default to generic values and attempt to move forward. |
