I don't speak python :slightly_smiling_face: but that should be possible
This is what I do in typescript to set an annotation for AKS

```transformations: [
    (obj: any) =&gt; {
      if (obj.kind === "Service" &amp;&amp; obj.metadata.name === "ingress-nginx-controller") {
        obj.metadata.annotations['<http://service.beta.kubernetes.io/azure-dns-label-name|service.beta.kubernetes.io/azure-dns-label-name>'] = 'my-dns-label'
      }
    },
  ],```

where would you retrieve the IP from? you can pass as many function arguments as you need

<@UCWG26BH7> essentially, creating an IP address in my Pulumi code and then passing it into the transformation function. So, the method signature would be `add_ingress_ip_address(obj, opts, ip_address_name)`

The full code might be:

```load_balancer_ip = pulumi_gcp.compute.GlobalAddress("default")
def add_ingress_ip_address(obj, opts):
  if obj['kind'] == 'Ingress':
    try:
      t = obj['metadata']['annotations']['<http://kubernetes.io/ingress.global-static-ip-name|kubernetes.io/ingress.global-static-ip-name>'] = opts.ip_name
    except KeyError:
      pass

# How to pass the IP name into here?
console_app_yaml = k8s.yaml.ConfigFile('console', file='sample.yaml', transformations=[add_ingress_ip_address])```

<@URABGC3T7> interesting. So that value can be set dynamically? Not just static within the function?

<@U02MS9N0SUQ>, I don't know exactly how the scoping works in python but at least in typescript, everything currently in scope is available in the function passed to transformations

Where is your opts.ip_name coming from?

As a rough guess based on my limited python understanding, if you define your ip_name before your function, then it should be available without passing as an arg and then so long as it is set before the function is run, the value should be correct

To ensure that, you might have to use the <https://www.pulumi.com/docs/intro/concepts/resources/#dependson|depends_on> arg to ensure it's resolved before your configFile resource is created
