Usage:
|
|
scripts/install-identity-writer-service.sh --host root@115.29.187.205 [--remote-root DIR]
|
|
|
|
Prepares the native identity-writer service and switches Gateway registration
|
|
persistence to Kafka delegation. The existing Gateway binary ignores the new
|
|
environment switch, so this is safe to run before staging the first release
|
|
that contains identity-writer.
