Secret Type - PROPERTIES

The PROPERTIES-Type is for rendering property-files based on secrets stored in HashiCorp Vault in the mountpoints for kv-1 or kv-2.
How To
First store some secrets in HashiCorp Vault:
$ vault write datasource/host host=localhost
$ vault kv put database/root username=root password=verysecure
After this create the following Vault-Resource and apply it to Kubernetes:
apiVersion: "koudingspawn.de/v1"
kind: Vault
metadata:
  name: properties-example
spec:
  type: "PROPERTIES"
  propertiesConfiguration:
    files:
      application.properties: |
        datasource.username={{ vault.lookupV2('database/root').get('username') }}
        datasource.password={{ vault.lookupV2('database/root').get('password') }}
        datasource.host={{ vault.lookup('datasource/host', 'host') }}
Now you should see, that the secret gets rendered and stored in Kubernetes and the Vault resource is also available:
$ kubectl get vault properties-example
NAME                  AGE
properties-example    10s
$ kubectl get secret properties-example
NAME                                   TYPE                                  DATA      AGE
properties-example                     Opaque                                1         9s
Rendering Options
The following expressions are available for rendering secrets stored in HashiCorp Vault:
Method

Description
vault.lookup(String path)
Java:HashMap
Looks inside a KV-1 Store for stored key-value pairs. The secrets are now available via .get('key')
vault.lookup(String path, String key)
String
Looks inside a KV-1 Store for stored key in key-value path.
vault.lookupV2(String path)
Java:HashMap
Looks inside a KV-2 Store for stored key-value pairs. The secrets are now available via .get('key'). It uses the latest version.
vault.lookupV2(String path, String key)
