Integrate grails with hashicorp vault

I'm trying to integrate hashicorp vault on a grails app. I wasn't able to find a tutorial or some help on the internet. Even the grails documentation doesn't comment anything on this topic.

Does anyone know how I can accomplish this?

I'm using grails 2.5.6

Edit

By integration I mean to let grails read properties from hashicorp vault instead of the ones that I defined in Config.groovy or DataSource.groovy or another properties in classpath. I defined a custom place holder that is able to reach my hashicorp vault but grails is not recognizing the properties I brought.

MyPlaceholderConfigurer.java

public class MyPlaceholderConfigurer extends GrailsPlaceholderConfigurer
final static Logger logger = Logger.getLogger(MyPlaceholderConfigurer.class);

public MyPlaceholderConfigurer(GrailsApplication application)
super(application);
logger.info("XXXXXXXXX: Started MyPlaceholderConfigurer");


@Override
protected void loadProperties(Properties props) throws IOException
logger.info("XXXXXXXXX: loadProperties()");
super.loadProperties(props);
Map<String, Object> vault = HashicorpVault.getSecrets();
props.putAll(vault);




resources.groovy

propertySourcesPlaceholderConfigurer(MyPlaceholderConfigurer, application)
environment = getUnrefreshedApplicationContext().getEnvironment()



Config.groovy

grails.config.locations = ["classpath:Principal.properties", "classpath:MyDatabase.groovy"]

There is no client library for groovy (or grails-plugin).

Since groovy works good with java you can just use the java-client library (https://www.vaultproject.io/api/libraries.html) the one you most likely want is https://github.com/BetterCloud/vault-java-driver since the Spring version of the driver can conflict with grails' Spring version. Also, the non-spring version targets java 7+ so you won't end up solving java 8 new features -problems that are not supported in old groovy versions bundled with grails 2.5.x

java-client

java 8 new features

Modify your BuildConfig.groovy to get the library:

BuildConfig.groovy

dependencies

...

compile 'com.bettercloud:vault-java-driver:3.1.0'

...



And follow the instructions on github page.

some.setting = SomeCustomConfigObject.get("myPassword")

SomeCustomConfigObject

get(String key)

myPassword
