When I saw the pulumi AI and documentation there is no such information related to getClusterArgs and the link or method is pointing to LookUpCluster, Any hint what’s happening here?

One oddity of the Go SDK is that the

Get*

functions are named

Lookup*

instead. So, rather than using

container.GetCluster

you’d use

container.LookupCluster

. Instead of using

&container.GetClusterArgs

you’d use

&container.LookupClusterArgs

. This page has an example (be sure to click the Go language selector): https://www.pulumi.com/registry/packages/gcp/api-docs/container/getcluster/

Thanks I was confused with pulumi AI and the documentation, How ever there is another issue I am using code but it’s not in the documentation (generated by AI) Idea is to generate a new cluster using the existing configuration

newCluster, err := container.NewCluster(ctx, "new-cluster", &container.ClusterArgs{
			AddonsConfig:              existingCluster.AddonsConfig,
			ClusterAutoscaling:        existingCluster.ClusterAutoscaling,
			DefaultSnatStatus:         existingCluster.DefaultSnatStatus,
			EnableKubernetesAlpha:     existingCluster.EnableKubernetesAlpha,
			EnableTpu:                 existingCluster.EnableTpu,
			IpAllocationPolicy:        existingCluster.IpAllocationPolicy,
			Location:                  pulumi.String("your-new-cluster-location"),
			LoggingService:            existingCluster.LoggingService,
			MaintenancePolicy:         existingCluster.MaintenancePolicy,
			NetworkPolicy:             existingCluster.NetworkPolicy,
			PodSecurityPolicyConfig:   existingCluster.PodSecurityPolicyConfig,
			PrivateClusterConfig:      existingCluster.PrivateClusterConfig,
			Project:                   newProjectID,
			ResourceLabels:            existingCluster.ResourceLabels,
			ResourceUsageExportConfig: existingCluster.ResourceUsageExportConfig,
		})

I’ve never tried something like that, and honestly don’t know if it would work. If you aren’t sure what settings to use, I would take a look at the

kubernetes-gcp-go

template (run

pulumi new kubernetes-gcp-go

and review the program created from it). Then compare that against what is already there.

sure thing! Idea is to collect the existing gcp cluster info (Auto pilot) including NAT, VPC (private and public) and create a new cluster using the same replica apart from the fixed IP address in a different project. Is that doable. How ever this my current code

package main

import (
	"<http://github.com/pulumi/pulumi-gcp/sdk/v6/go/gcp/container|github.com/pulumi/pulumi-gcp/sdk/v6/go/gcp/container>"
	"<http://github.com/pulumi/pulumi/sdk/v3/go/pulumi|github.com/pulumi/pulumi/sdk/v3/go/pulumi>"
)

func main() {
	pulumi.Run(func(ctx *pulumi.Context) error {
		// Get existing GKE cluster
		existingCluster, err := container.LookupCluster(ctx, &container.LookupClusterArgs{
			Location: pulumi.StringRef("your-existing-cluster-location"),
			Name:     "your-existing-cluster-name",
			Project:  pulumi.StringRef("your-existing-project-id"),
		})
		if err != nil {
			return err
		}

		// Change "your-new-project-id" to the new project ID where you want to create the cluster
		newProjectID := pulumi.String("your-new-project-id")

		// Create a new GKE cluster with the same settings in a different project
		newCluster, err := container.NewCluster(ctx, "new-cluster", &container.ClusterArgs{
			AddonsConfig:              existingCluster.AddonsConfig,
			ClusterAutoscaling:        existingCluster.ClusterAutoscaling,
			DefaultSnatStatus:         existingCluster.DefaultSnatStatus,
			EnableKubernetesAlpha:     existingCluster.EnableKubernetesAlpha,
			EnableTpu:                 existingCluster.EnableTpu,
			IpAllocationPolicy:        existingCluster.IpAllocationPolicy,
			Location:                  pulumi.String("your-new-cluster-location"),
			LoggingService:            existingCluster.LoggingService,
			MaintenancePolicy:         existingCluster.MaintenancePolicy,
			NetworkPolicy:             existingCluster.NetworkPolicy,
			PodSecurityPolicyConfig:   existingCluster.PodSecurityPolicyConfig,
			PrivateClusterConfig:      existingCluster.PrivateClusterConfig,
			Project:                   newProjectID,
			ResourceLabels:            existingCluster.ResourceLabels,
			ResourceUsageExportConfig: existingCluster.ResourceUsageExportConfig,
		})
		if err != nil {
			return err
		}

		ctx.Export("newClusterName", newCluster.Name)
		ctx.Export("ClusterEndpoint", newCluster.Endpoint)
		return nil
	})
}

I’m checking now to see if the idea of using

LookupCluster

to feed information into

NewCluster

is supported/feasible. My IDE definitely doesn’t like your code; it’s throwing all kinds of type errors.

yes, same here. Do let me know if you find anything

I haven’t gotten any responses from the engineering team yet. My advice to you, if this is time-sensitive, would be to use the

kubernetes-gcp-go

template and iterate on that to create a matching resource.

Ah! I will wait for the response because it's seems very confusing to me. I even tried pulumi import BTW

pulumi import

should generate code for you, and you can then duplicate that code to create another resource. But as someone else pointed out in another thread, with an Autopilot cluster a lot of the settings won’t come in (because Autopilot handles all that).
