My Pulumi creates a new GKE cluster on every run. Anyone seen this behavior? I saw someone mention adding networking config was a workaround for them but the params that they mentioned don’t seem to work in the current version of the libraries.

Does it tear down the old cluster too? As in, is it replacing or just creating the new cluster?

I believe it says “recreate” when its doing it and it just creates a new cluster. The old clusters I have to go back and manually delete. When I do a pulumi destroy, it tells me that its set to not delete clusters but not sure if that is related to the actual issue…
I’ve added network and subnetwork to the container.NewCluster call and am trying it again after removing all of the clusters.
Copy code

Running in more verbose mode and it looks like its replacing because of the nodeConfig diff. I changed the network and subnetwork so that may be legitimate. I will wait until this run finishes then try again to see if I end up with a third cluster.
Yep, now a third cluster:

Something wrong with my container.NewCluster config?
Copy code
cluster, err := container.NewCluster(ctx, projectName, &container.ClusterArgs{
		InitialNodeCount: <http://pulumi.Int|pulumi.Int>(1),
		//RemoveDefaultNodePool: pulumi.Bool(true),
		Location:         pulumi.String(location),
		MinMasterVersion: pulumi.String("latest"),
		Network:          Network.ID(),
		Subnetwork:       Subnetwork.ID(),
		NodeConfig: &container.ClusterNodeConfigArgs{
			MachineType: pulumi.String("n1-standard-2"),
			DiskSizeGb:  <http://pulumi.Int|pulumi.Int>(30),
			OauthScopes: pulumi.StringArray{
				pulumi.String("<https://www.googleapis.com/auth/compute>"),
			},
			Preemptible: pulumi.Bool(false),
		},
	})
Here’s the diff. Looks like node config. Not sure why it is changing every run…
Copy code
~ nodeConfig: {
          ~ oauthScopes: [
              - [0]: "<https://www.googleapis.com/auth/monitoring>"
              - [1]: "<https://www.googleapis.com/auth/logging.write>"
            ]
        }

                  ~ nodeLocations           : [
                        [0]: "us-central1-b"
                      ~ [1]: "us-central1-c" => "us-central1-f"
                        [2]: "us-central1-a"
                    ]
