Browse to the Amazon RDS console to monitor your database deployment. Click on your database name. Under Summary, the DB instance status should be available. If it isn’t quite ready (perhaps still doing the initial backup), you can hit refresh every couple of minutes and wait for it to be in the available state.
In the Connectivity & security section, find the Endpoint of the database instance (e.g. runningamazonec2workloadsatscale.ckhifpaueqm7.us-east-1.rds.amazonaws.com ).
Seed the database for the application environment. Replace %endpoint% with the database instance endpoint noted in the last step:
mysql -h %endpoint% -u dbadmin --password=db-pass-2020 -f koel < koel.sql
This command will not return any output if it is successful.
