Planning failed: Terraform encountered an error while generating this plan

[umar-shabbir]

I am trying to follow getting started with Minikube instructions and I get following error when running terraform plan

Planning failed. Terraform encountered an error while generating this plan.

╷
│ Error: Plugin did not respond

│ The plugin encountered an error, and failed to respond to the plugin.(*GRPCProvider).ReadResource call. The plugin logs may contain more details.

Steps tried:

• I have followed the Hello Minikube tutorial before starting Theia Cloud. Steps in that tutorial worked fine for me.
• Tried setting KUBECONFIG and KUBE_CONFIG_PATH environment variables
• Tried deleting all terraform lock files and running terraform init, terraform plan again
• Tried minikube delete and following all the steps again
• Uninstall minikube, remove .kube from user profile. Reinstall and try all steps again

Any suggestions for above issue are appreciated. If someone has a working sample of Theia Cloud with Minikube tested on Windows 11, that can be helpful too.

Additional Information:
Platform: Windows 11
Terraform: 1.7.0
Minikube: 1.32.0
VirtualBox: 7.0.12

Hi, I am usually working in Ubuntu but I got my hands on a windows 10 machine and tested the setup there. Sorry that I can't test on windows 11.

On my first run I got the same error as you posted above.
I then ran git clean -xfd (to delete any local terraform state) and minikube delete (to delete the failed minikube VM). I think this is the same as the steps you tried above.
In order to get more logs from terraform I ran export TF_LOG=true (using the git bash on windows). This will log the trace logs to the console.
Without any other change the setup worked now. (Or nearly, I got two more error, because I did not have kubectl and ruby installed, but with those the setup worked):

This was not run as an administrator, I just had to accept some changes to the firewall rules while the cluster was created by terraform.

So maybe retrying again on a clean state will help you. Otherwise the terraform logs may give further hints.

@jfaltermeier thanks for trying it out and sharing the result.
I did try on a clean setup by following what you have described above. Though it solved the previous error but now I am getting another error.
Error: Kubernetes cluster unreachable: invalid configuration: [client-cert-data and client-cert are both specified for minikube. client-cert-data will override., client-key-data and client-key are both specified for minikube; client-key-data will override]

From the logs I found that this same error appears for following:

1. with provider["registry.terraform.io/hashicorp/kubernetes"]
2. with module.helm.helm_release.cert-manager
3. with module.helm.helm_release.theia-cloud-crds[0]

Currently I am trying to understand and debug this error. Just though to share it here too, in case you have any information about this particular error.
