Support variables in core.properties and import parameters

[qlereboursBS]

What I'm trying to do
Run an import (curl http://localhost:8983/solr/my-core/dataimport?command=full-import) with a config file that includes parameters:

// db-data-config.xml contains:
  <dataSource type="JdbcDataSource"
			driver="org.postgresql.Driver"
            url="jdbc:postgresql://${solr.sgbd.host}:${solr.sgbd.port}/${solr.database.name}"
            user="${solr.sgbd.user}"
            password="${solr.sgbd.password}" />

What I tried

1. Having a core.properties that includes those properties. It was working with Solr 8 and it's not working after my upgrade to Solr 9 + independent DIH
2. Passing the properties through the URL of the import `curl http://localhost:8983/solr/my-core/dataimport?command=full-import&solr.sgbd.host=postgres&solr.sgbd.port=5432&solr.database.name=my_database&solr.sgbd.user=my_user&solr.sgbd.password=my_password"

If my second try doesn't work, how can I use variables inside my XML file?

Thanks

I found a way, passing properties to Solr in my docker-compose file, using SOLR_OPTS environment variable:

    environment:
      SOLR_OPTS: >
        -Dsolr.sgbd.host=postgres
        -Dsolr.sgbd.port=5432
        -Dsolr.database.name=my_database
        -Dsolr.sgbd.user=my_user
        -Dsolr.sgbd.password=my_password

which are then given to the solr command line.
However, i think it's still a problem that variables from core.properties are not used
