I’m getting the following error:

Cannot call '.get' during update or preview

and I think it’s from the following new TS I added to my index.ts:

let apiIntentRobotServiceAccount = new k8s.core.v1.ServiceAccount(
  'api-intent-robot-service-account', {
    metadata: {
      name: 'api-intent-robot',
      namespace: context.inferredNamespace
    }
  }
)

let apiIntentEphemeralRobotRole = new k8s.rbac.v1.Role(
  'api-intent-ephemeral-robot-role',
  {
    metadata: {
      name: 'api-intent-robot-role',
      namespace: EPHEMERAL_NAMESPACE_NAME
    },
    rules: [
      {
        apiGroups: [''],
        resources: ['pods', 'pods/status'],
        verbs: ['get', 'create', 'patch', 'delete', 'list', 'status']
      }
    ]
  }
)

let apiIntentEphemeralRolebinding = new k8s.rbac.v1.RoleBinding(
  'api-intent-ephemeral-robot-rolebinding',
  {
    metadata: {
      name: 'api-intent-robot-rolebinding',
      namespace: EPHEMERAL_NAMESPACE_NAME
    },
    roleRef: {
      name: apiIntentEphemeralRobotRole.metadata.get().name,
      apiGroup: apiIntentEphemeralRobotRole.apiVersion,
      kind: apiIntentEphemeralRobotRole.kind
    },
    subjects: [
      {
        kind: apiIntentRobotServiceAccount.kind,
        name: apiIntentRobotServiceAccount.metadata.get().name,
      }
    ]
  })

Am I not allowed to get the name of a resource to use in the spec of another resource?

@cuddly-leather-18640 try this instead:

apiIntentRobotServiceAccount.metadata.apply(m => m.name)

it worked!

👍🏼

is there documentation on this somewhere? I’m surprised that

get

doesn’t give me the resource

@cuddly-leather-18640 yes, these docs are generated from the typescript comments: https://pulumi.io/reference/pkg/nodejs/@pulumi/pulumi/index.html#method-get

There's some light conceptual docs on this here https://pulumi.io/reference/programming-model.html#outputs. But more is definitely needed. /cc also @lemon-spoon-91807.

So if you are using vscode or something like that, hovering over

get

should tell you what the method does.

ah gotcha, even if those resources already exist pre-pulumi? I’ve already written and applied a k8s yaml spec with a service account, role and rolebinding. Now I’m moving this yaml to pulumi and it seems that

preview

isn’t seeing what I’ve already applied

Pulumi will not know about them if you didn’t create them with Pulumi

ah gotcha

@cuddly-leather-18640 since this a common pattern I actually added a utility function to our library few days ago.

apiIntentRobotServiceAccount.metadata.apply(m => m.name)

you can just write:

import { getName} from '@solvvy/pulumi-util';

getName(apiIntentRobotServiceAccount);
