Trouble using Spring Config Server in jhipster-registry - jhipster

Question

I created a microservice architecture using JHipster. I am using the jhipster-registry v2.8.0. I renamed the 'dev' profile to 'devdmi' because I will have many 'dev' profiles. It is working OK using the "dev,native" profiles for the jhipster-registry and each microservice including it's application-devdmi.yml / boostrap-devdmi.yml files.
I tried to convert this configuration over to using a Git repo. I built my Git repo with .yml files, but I'm not exactly sure of the configuration to use. At the moment I've got:
MyConfig/app1/MyApp1-devdmi.yml
MyConfig/app2/MyApp2-devdmi.yml
I also tried using:
MyConfig/MyApp1-devdmi.yml
MyConfig/MyApp2-devdmi.yml
In MyApp1, I renamed src/main/resources/config/application-devdmi.yml to application-devdmi.yml.bak hoping it would pick up the config from the jhipster-registry acting as a Spring Cloud Config Server.
In MyApp1, I have a bootstrap-devdmi.yml with:
spring:
application:
name: my-app-1
cloud:
config:
fail-fast: true
uri: http://admin:${jhipster.registry.password}#my.host.com:8761/config
name: MyApp1
profile: devdmi
label: master
The jhipster-registry starts up and shows it is connected to the Git repo by looking at the Configuration webpage.
MyApps1 doesn't start and throws an error about Liquibase not knowing which database to connect to:

Any ideas?
