That error sounds like it may be a problem with invalid YAML in the chart. The code snippet you posted looks right to me, and I verified that the linked example is working.

Hi @gorgeous-egg-16927 sorry I forgot to update this one. I had a problem with input/output extrapolation elsewhere (as usual) leading to this error. I’m still stuck though, because no matter how I try to access the

statefulSet

of this chart I get with

getResource()

, its always

undefined

I can’t access its properties (

metadata

,

spec

, etc). I try to

apply()

or

interpolate

but there’s no way to get anything out of a

getResource()

at that point for me. Doing like your example yields

undefined

too.

This is working for me:

const wordpress = new k8s.helm.v2.Chart("wpdev", {
    repo: "stable",
    chart: "wordpress",
    version: "9.0.3",
});

// Export the public IP for WordPress.
export const frontend = wordpress.getResource("v1/Service", "wpdev-wordpress");

I did notice that the

frontendIp

was undefined running on docker for mac because the loadbalancer status field is actually

frontend.status.loadBalancer.ingress[0].hostname

. This varies depending on which k8s you’re running.

I’m on aws eks, I didn’t try on any other k8s instance yet, but shouldn’t

getResource()

returns a component of the expected type with its properties set no matter what ? How can I rely on it if it does not ? I need the

StatefulSet.spec.serviceName

and it seems I can’t get it and will have to rely on a manual concatenation guess.

Sorry, I think my previous answer was confusing. Yes,

getResource

works as you expect. However, it returns an Output, and it looks like you’re trying to use a normal string interpolation rather than

pulumi.interpolate

to build the

uri

string. I suspect this is the actual problem.

As I said I tried all of these :

const uri = `mongodb://${this.statefulSet.spec.serviceName}:27017`

const uri = pulumi.interpolate`mongodb://${this.statefulSet.spec.serviceName}:27017`

const uri = this.statefulSet.spec.apply(spec => `mongodb://${spec.serviceName}:27017`)

Always get something like

unable to get serviceName from undefined

One thing I don’t understand is that I actually get the errors during the preview, while the resource does not actually exist yet, which makes sense, but pulumi should know that, right ? I ensured the

replicasetName

variable I use in

getResource()

is the valid expected name of the resource, so we should be safe here.

Is

replicasetName

an

Output<string>

, or a

string

?

that’s a simple raw

string

For TypeScript, it will return

undefined

I think the chart is having its own namespace yes, let me check that

Yes, that’s right

Thanks it finally works ! Sorry I didn’t notice this earlier 😞

Glad to hear it! 🙂 I opened https://github.com/pulumi/pulumi-kubernetes/issues/1173 to make this a little easier to track down in the future

Would definitely help, thanks ! 🙂
