Example for AWS System Manager Parameter Store

To enable distributed configuration a src/main/resources/bootstrap.yml configuration file must be created and configured to use Parameter Store:

bootstrap.yml

micronaut:
        name: hello-world
        enabled: true

You can configure shared properties by going into the AWS Console → System Manager → Parameter Store

Micronaut will use a hierarchy to read the configuration values, and supports String, StringList, and SecureString types.

You can make environment specific configurations as well by including the environment name after an underscore _. For example if your micronaut.application.name setting is set to helloworld then providing configuration values under helloworld_test will be applied only to the test environment.

For example, if the configuration name /config/application_test/server.url is configured in AWS Parameter Store, then any application connecting to that parameter store can retrieve the value using server.url. If the application has micronaut.application.name configured to be , then a value with the name /config/myapp_test/server.url will override the value just for that application.

Each level of the tree can be composed of key=value pairs. If you want multiple key value pairs, set the type to ‘StringList’.

The https://github.com/micronaut-projects/micronaut-examples/aws repository showcases a sample application using this feature.
