how did you try doing it with

apply

- you need to invoke apply and interpolate in the correct place, there are examples here https://github.com/jaxxstorm/pulumi-examples/blob/main/typescript/aws/s3-cloudfront/index.ts#L50-L66

Thanks @billowy-army-68599 I have attempted this again using the

apply

example.

export const clusterAutoScalingPolicy = new aws.iam.Policy("clusterAutoScalingPolicy", {
    policy: pulumi
        .all([cluster.core.cluster.name])
        .apply(([clusterName]) => {
            JSON.stringify({
                Version: "2012-10-17",
                Statement: [
                    {
                        Sid: "VisualEditor0",
                        Effect: "Allow",
                        Action: [
                            "autoscaling:SetDesiredCapacity",
                            "autoscaling:TerminateInstanceInAutoScalingGroup"
                        ],
                        Resource: "*",
                        Condition: {
                            StringEquals: {
                                [clusterName]: "owned"
                            }
                        }
                    },
                    {
                        Sid: "VisualEditor1",
                        Effect: "Allow",
                        Action: [
                            "autoscaling:DescribeAutoScalingInstances",
                            "autoscaling:DescribeAutoScalingGroups",
                            "ec2:DescribeLaunchTemplateVersions",
                            "autoscaling:DescribeTags",
                            "autoscaling:DescribeLaunchConfigurations"
                        ],
                        Resource: "*"
                    }
                ]
            })
        })
}, {
    dependsOn: [cluster]
});

I like this method, but the issue is that the policy argument for

aws.iam.Policy

needs to be of type

string | PolicyDocument

, But, the response of

pulumi.all.apply

is of type

OutputInstance<void>

. Any ideas of how to resolve the type conflict?

cast it: https://github.com/jaxxstorm/pulumi-examples/blob/main/typescript/aws/s3-cloudfront/index.ts#L65

@billowy-army-68599 After casting, I am getting the following error:

error: aws:iam/policy:Policy resource 'clusterAutoScalingPolicy' has a problem: Missing required argument: The argument "policy" is required, but no definition was found.. Examine values at 'Policy.Policy'.

Code:

export const clusterAutoScalingPolicy = new aws.iam.Policy("clusterAutoScalingPolicy", {
    policy: pulumi
        .all([cluster.core.cluster.name])
        .apply(([clusterName]) => {
            JSON.stringify({
                Version: "2012-10-17",
                Statement: [

                            }
                        }

Sorry, still on my todo list

@billowy-army-68599 Following up on this. I could not get this working with any of the above mentioned solutions. I ended up just manually naming the cluster and using that specified cluster name in the string interpolation.

@lively-needle-84406 sorry for the delay here, I was at re:invent last week so had limited time to sit down and go through issues. Here’s the solution

const policyDoc = cluster.core.cluster.name.apply((name) =>
  JSON.stringify({
    Version: "2012-10-17",
    Statement: [
      {
        Sid: "VisualEditor0",
        Effect: "Allow",
        Action: [
          "autoscaling:SetDesiredCapacity",
          "autoscaling:TerminateInstanceInAutoScalingGroup",
        ],
        Resource: "*",
        Condition: {
          StringEquals: {
            [`aws:ResourceTag/k8s.io/cluster-autoscaler/${name}`]: "owned",
          },
        },
      },
      {
        Sid: "VisualEditor1",
        Effect: "Allow",
        Action: [
          "autoscaling:DescribeAutoScalingInstances",
          "autoscaling:DescribeAutoScalingGroups",
          "ec2:DescribeLaunchTemplateVersions",
          "autoscaling:DescribeTags",
          "autoscaling:DescribeLaunchConfigurations",
        ],
        Resource: "*",
      },
    ],
  })
);

export const clusterAutoScalingPolicy = new aws.iam.Policy(
  "clusterAutoScalingPolicy",
  {
    policy: policyDoc,
  }, {
    dependsOn: [cluster],
  }
);
