Terraform Provisioning: error: The gcp auth plugin has been removed.

[scottford-io]

Describe the bug

Provisioning the microservices demo with Terraform produces the following error:

│ Error running command 'kubectl apply -k ../kustomize/': exit status 1. Output: + kubectl apply -k ../kustomize/
│ error: The gcp auth plugin has been removed.
│ Please use the "gke-gcloud-auth-plugin" kubectl/client-go credential plugin instead.
│ See https://cloud.google.com/blog/products/containers-kubernetes/kubectl-auth-changes-in-gke for further details

This happens when the null_resource is executed to deploy to the cluster ...

https://github.com/GoogleCloudPlatform/microservices-demo/blob/main/terraform/main.tf#L73-L83

I was able to get around this with the following:

export USE_GKE_GCLOUD_AUTH_PLUGIN=True
gcloud container clusters get-credentials <cluster_name> --zone <some>
kubectl apply -k ../kustomize/

After getting this working manually, I was able to run terraform apply without any issues. More information can be found here:

To Reproduce

1. Clone the repo
2. cd terraform
3. create terraform.tfvars
4. Run terraform init
5. Run terraform apply -auto-approve
6. See error

@scottford-io, thanks so much for reporting this clear and detailed GitHub issue (and for including the steps you took to get things working). Anyone else that encounters this issue will find your report useful.

I am going to de-prioritize this issue because:

1. The error message is actionable and informative (e.g., Please use the "gke-gcloud-auth-plugin" ... Go to https://cloud.goo...).
2. The issue seems specific to the gcloud command-line tool. I do not think there's anything Online Boutique (github.com/GoogleCloudPlatform/microservices-demo) can do to address this issue — other than updating documentation.

@NimJay if you do not see it as an issue, I recommend to close it with the resolution from your previous comment
