flyway error: Unable to obtain connection from database for user 'null' - postgresql

Question

im trying to run flyway docker image 7.3.2 against a postgres db on kubernetes:
When i run the job my output is:
Flyway Community Edition 7.3.2 by Redgate
ERROR:
Unable to obtain connection from database (jdbc:postgresql://xxx.eu-west-2.rds.amazonaws.com:5432/xxx flyway.user=postgres flyway.password=****************) for user 'null': The server requested password-based authentication, but no password was provided.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
SQL State : 08004
Error Code : 0
Message : The server requested password-based authentication, but no password was provided.
Caused by: org.postgresql.util.PSQLException: The server requested password-based authentication, but no password was provided.
the settings it outputs are correct and should enable a connection.
I pass in my flyway.conf via a configmap which is:
apiVersion: v1
kind: ConfigMap
metadata:
name: flyway-configmap
data:
flyway.conf:
flyway.url=jdbc:postgresql://xxx.eu-west-2.rds.amazonaws.com:5432/xxx
flyway.user=postgres
flyway.password=xxx
anyone able to assist in what im doing wrong?

Answer 1

If that is literally your ConfigMap, then it is missing the | character after the : which would make that yaml key into a newline delimited scalar. That theory also squares up with your error message showing that the entire thing is taken as the value of flyway.url
What you want:
flyway.conf: |
flyway.url=jdbc:postgresql://xxx.eu-west-2.rds.amazonaws.com:5432/xxx
flyway.user=postgres
flyway.password=xxx
