JarCastingInterpolates environment variables in Dropwizard YAML configurations.
Usage
In your Application class
public void initialize( Bootstrap bootstrap ) {
bootstrap.addBundle( new EnvironmentVariableInterpolationBundle() );
In your YAML configuration
# This is just an example
mongo:
host: ${MONGO_HOST}
port: ${MONGO_PORT}
Notes
This bundle will fail fast, i.e. if an environment variable is not found, it will throw an EnvironmentException:
EnvironmentException: The environment variable 'MONGO_HOST' is not defined; could not substitute the expression '${MONGO_HOST}'.
