Cannot assign '{}' to 'aws:alb/ListenerDefaultAction:ListenerDefaultAction': type: Missing required property 'type'

[devopsmash]

What happened?

I'm trying to create a new aws.alb.Listener in order to attach it to a new aws.alb.LoadBalancer and to reference the defaultActions to a new aws.lb.TargetGroup with this example (link) with YAML syntax and with the Pulumi Kubernetes Operator (link).

I was able to create the aws.alb.LoadBalancer & aws.lb.TargetGroup successfully, but when I tried to create the aws.alb.Listener and reference in the defaultActions (which is list of maps) the new targetGroupArn from my new aws.lb.TargetGroup I got the following error:

Example

apiVersion: pulumi.com/v1
kind: Program
metadata:
  name: test
program:
  variables:
    ProfileName: test-profile
    VPC: vpc-e4fb608f
  resources:
    alb:
      type: aws:alb:LoadBalancer
      properties:
        tags: 
          Name: test-lb
        name: testing
        subnets: 
          - subnet-eacf3697
          - subnet-939b18f8
    TG:
      type: aws:alb:TargetGroup
      properties:
        port: 80
        protocol: 'HTTP'
        vpcId: ${VPC} 

    testTargetGroupAttachment:
      type: aws:alb:TargetGroupAttachment
      properties:
        targetGroupArn: ${TG.arn}
        targetId: ${ec2.id}
        port: 80

    httpListener:
      type: aws:alb:Listener
      properties:
        loadBalancerArn: ${alb.arn}
        port: 80
        protocol: "HTTP"
        defaultActions: 
          - type: "forward"
            targetGroupArn: ${TG.arn}

Any chance that there is a problem when the pulumi k8s operator is trying to convert the list of maps with a variable inside?

Note: This not happens when I'm trying to run it driectly in my laptop, apperntly it happens only in the k8s operator.

A similar standalone program seems to type-check correctly, so it does sound like an operator problem, potentially:

name: aws-yaml
runtime: yaml
variables:
    ProfileName: test-profile
    VPC: vpc-e4fb608f
resources:
  alb:
    type: aws:alb:LoadBalancer
    properties:
      tags: 
        Name: test-lb
      name: testing
      subnets: 
        - subnet-eacf3697
        - subnet-939b18f8
  TG:
    type: aws:alb:TargetGroup
    properties:
      port: 80
      protocol: 'HTTP'
      vpcId: ${VPC} 

  testTargetGroupAttachment:
    type: aws:alb:TargetGroupAttachment
    properties:
      targetGroupArn: ${TG.arn}
      targetId: someid
      port: 80
  httpListener:
    type: aws:alb:Listener
    properties:
      loadBalancerArn: ${alb.arn}
      port: 80
      protocol: "HTTP"
      defaultActions: 
        - type: "forward"
          targetGroupArn: ${TG.arn}

Are you running an operator on your laptop, or a standalone program like I did.

targetId: ${ec2.id}

Probably irrelevant, but what is ec2? Are there some other bits in your program?

Hi @mikhailshilkov ,

Probably irrelevant, but what is ec2? Are there some other bits in your program?

I have created ec2 as well, but I didn't add the relevant config here because I thought that it's irrelevant, here is a sample for that config:

    ec2:
      type: aws:ec2:Instance
      properties:
        ami: ami-089c26792dcb1fbd4
        iamInstanceProfile: ${ProfileName}
        instanceType: t3.micro
        keyName: test   

Are you running an operator on your laptop, or a standalone program like I did.

I'm running kind (local k8s) with the pulumi k8s operator as a pod, it seems that this happens only in the k8s operator.
