Referencing Values

To reference a value, use this format:

${vault::<secret_engine>/<path_to_secret>.<key_name>}

By default, version 2 of the KV engine is used.

If an environment variable needs to be referenced within a path, use this format within the path to the secret or the key name:

$[ENVIRONMENT_VARIABLE_NAME]

One may need to reference an environment variable in order to account reference environment-specific secrets. For instance, there is one API Key for the development environment and another for the production environment.

Example

To retrieve a value from the Key/Value secrets engine exposed as "secret", stored at "test/mule-sample", with a key of "name", use this format:

${vault::secret/test/mule-sample.name}

It could also be specified with an environment variable like this (where an environment variable called ENV is set to test):

${vault::secret/$[ENV]/mule-sample.name}

Publishing to a Private Exchange

To publish to a private exchange, some updates are necessary in the pom.xml file and your Maven settings.xml.

Update the groupId to the organization ID used by your organization on the Anypoint platform.

In addition, update the url in the distributionManagement section of the pom to the following, replacing ${orgId} with your Organization ID:

https://maven.anypoint.mulesoft.com/api/v1/organizations/${orgID}/maven

Add a server for the exchange repository in your Maven settings.xml file with the username and password to use for AnyPoint Exchange.

After it is published in the exchange, the dependency in a project would change to look like this:

<dependency>
    <groupId>${orgId}</groupId>
    <artifactId>vault-connector</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <classifier>mule-plugin</classifier>
</dependency>
