The Keycloak server is currently configured via a keycloak-server.json
file.  We are converting this to configuration through
standalone.xml/domain.xml.

To automatically upgrade, I need to read keycloak-server.json and write
back to standalone.xml.  I can easily add the operations to do this at
parse time.  The parser has this method:

@Override
public void readElement(final XMLExtendedStreamReader reader, final
List<ModelNode> list) throws XMLStreamException

Reading an external resource from the subsystem parsing doesn't feel right to me. Is the goal to move away from the keycloak-server.json to using the management model?

If that is the goal then a better solution might be to have some sort of migration operation that would read the file and create the subsystem model. Then after that the keycloak-server.json is ignored and the *.xml file will be used.

 

So one way to do this is to parse keycloak-server.json at this time and
add operations to the list.

That puts everything into the management model.  But nothing will be
written to standalone.xml unless someone manually does a write operation
from CLI.

A write will be triggered if you make a change to the management model.

 

So my question is, what is the best way to accomplish this?  Is there a
good, safe way to manually trigger a flush to standalone.xml at this
point or at some later point during startup?

Not really an answer, but I hope there is not a way to trigger a write :)
