Manifest

You need to add some special manifest? For this case, you can usee the mainfest helper:

manifest:
  - apiVersion: VERSIONHERE
    kind: KINDHERE
    content:
      SPEC/DATA...
  - apiVersion: VERSIONHERE
    kind: KINDHERE
    content:
      SPEC/DATA...

Example:

  - apiVersion: networking.k8s.io/v1beta1
    kind: Ingress
    content:
      metadata:
        name: foo
        namespace: production
      spec:
        rules:
          - host: example.net
            http:
              paths:
                - path: /bar
                  backend:
                    serviceName: service1
                    servicePort: 80
                - path: /foo
                  backend:
                    serviceName: service1
                    servicePort: 80
