Migrating existing LinkedPipes ETL instance to a new IRI scheme

Migrating existing LinkedPipes ETL instance to a new IRI scheme

Sometimes it is necessary to migrate an existing LP-ETL instance to a new IRI scheme. An example of such a situation may be implementing a reverse proxy, HTTPS, password protection or simply moving the entire instance to another server. You can use this guide to preserve pipelines, templates and executions, which need to be rewritten using the new IRI scheme. Using the defaults and demonstrating on changing from http://localhost:8090 to https://localhost

1. Update configuration.properties to reflect the new IRI scheme.

   vi /opt/lp/etl/deploy/configuration.properties
   

   and change from

   executor.execution.uriPrefix = http://localhost:8090/resources/executions/
   domain.uri = http://localhost:8090
   

   to

   executor.execution.uriPrefix = https://localhost/resources/executions/
   domain.uri = https://localhost
   

   to reflect the new IRI scheme.

2. in {data}/working run

   find . -name *.jsonld | xargs sed -i 's_http://localhost:8090_https://localhost_g'
   find . -name *.trig | xargs sed -i 's_http://localhost:8090_https://localhost_g'
   

3. in {data}/storage run

   find . -name *.trig | xargs sed -i 's_http://localhost:8090_https://localhost_g'
   

4. Restart LP-ETL and you are done
