  - name: bitnami
    url: https://charts.bitnami.com/bitnami

releases:
  - name: app
    chart: bitnami/nginx
    namespace: test
    wait: true
    values:
      - values-secret.yaml

Step 3. Create values-secret.yaml

{{ defineDatasource "vault" "vault:///secret/data/test" }} # `data` is required for vault kv2

secret: {{ (ds "vault").data.hello }}
revesion_of_secret: {{ (ds "vault").metadata.version }}

Step 4. Run helmwave build --templater gomplate

You will get

secret: world
revision_of_secret: 2
