GKE Autopilot is recreated without any changes to node_config

[ocervell]

Describe what happened

GKE Autopilot is recreated without any changes to node_config.

Running pulumi up twice shows on the second up that the cluster needs to be replaced because nodeConfig is different:

gcp:container:Cluster                    gke-cluster            replace     [diff: ~nodeConfig]

Sample program

import pulumi
import pulumi_gcp as gcp

config = pulumi.Config()
provider_cfg = pulumi.Config("gcp")
project = provider_cfg.require('project')
region = provider_cfg.get('region', 'europe-west1')
cluster = gcp.container.Cluster("gke-cluster",
    location=region,
    enable_autopilot=True,
    node_config={
        "oauth_scopes": ["https://www.googleapis.com/auth/cloud-platform"]
    }
)

Hi @ocervell - thank you for reporting this issue, and we're sorry you're having trouble.

I've been able to reproduce this behavior. Here's what happens when I look at the details after pulumi preview:

This unfortunately appears to be a limitation of GKE autopilot in conjunction with node_config.oauth_scopes that's been the case for quite a while. The recommendation seems to be to not use node_config.oauth_scopes.

It looks like you're running into the same issue as this Terraform user: hashicorp/terraform-provider-google#13542.
