Overview
User documentation: SDN-R Upgrade Procedure
Migration Concept El Alto → Frankfurt
...
- Migration is like re-installing a backup and fills data into database.
- User is responsible to have SDNC cluster in approppriate status to receive backup/migration data
...
- Response: 200 OK If job is accepted
- Response: 4xx if not acceped (e.g. already running or file not found or invalid)
...
This will be a CommandLineTool for:
- (re)initialize/upgrade SDN-R DB
- backup and restore SDN-R DB data
- create unit test init-file
Its sources are located in the data-provider subproject of ccsdk/features sdnr/wt projects but it won't be deployed as a bundle for opendaylight, so that it is possible to run it independently from any sdnc.
Database Init Container
This Tool will be executed inside the sdnc container with a seperate flag (env-var) 'SDNRINIT', so that the tool will be executed once and the container will be stopped afterwards. The parameters will also pushed within environment variables
- SDNRDBURL
- SDNRDBUSERNAME
- SDNRDBPASSWORD
User password coding is "ASCII". If one of SDNRDBUSERNAME or SDNRDBPASSWORD is empty the no-authentication is configured.
Security enabled/disabled by SDNRDBURL, by "https" or "http". Default is "http://sdnrdb:9200". All client certs are accepted.
Example
- SDNRDBURL="http://sdnrdb:9200"
- SDNRDBUSERNAME="fdjafls"
- SDNRDBUSERPASSWORD="57!232#"
Structure
In Elasticsearch(ES) there are no database and datatables. Instead there are indices and doctypes. Since version 5.0 of ES only one doctype per index is allowed, so that we can say our index equals the table in a normal relational database like mariadb.
