How to run

Create an AWS Secret

Create an AWS Secret from your AWS Management Console, name it as local-test.

If you don't know how to that, read this article.

If you already have the secret but with a different name, make sure to edit application.properties, and change spring.datasource.username field.

Export AWS ACCESS KEY and ID as environment variables

Need to export the following environment variables in the same console that you run the application,

$ export AWS_ACCESS_KEY_ID=YOUR_ACCESS_KEY
$ export AWS_SECRET_ACCESS_KEY=YOUR_SECRET_KEY
$ export AWS_REGION=YOUR_ACCOUNT_REGION

Bring up docker and create table

$ cd docker && docker-compose up -d
$ ./db_initializer.sh

Run the application

$ ./mvnw spring-boot:run

Test it!

Open your browser and hit localhost:8080/v1/users/. You should see JSON output.

Custom values

To change any values like database name, port, host or even the secret name, either change the application properties or export the environment variables.
