Plugin did not respond

I am trying to run this using minikube, using the docker driver.

When running terraform apply, I get this error:

2023-08-30T15:53:27.874+0200 [ERROR] plugin.(*GRPCProvider).ApplyResourceChange: error="rpc error: code = Unavailable desc = error reading from server: EOF"
2023-08-30T15:53:27.883+0200 [ERROR] vertex "module.cluster.minikube_cluster.cluster" error: Plugin did not respond

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

Any ideas on how to debug this? Also, I don't know how to access these plugin logs. Any help is appreciated!

Hey @MixusMinimax,

could you clarify on which terraform configuration this error happens and which instructions you were following?

In the past we had similiar issues those were most of the time fixed by cleaning the terraform lock file and modules and retrying. Could you try that?

I actually see some docker (maybe permission) related things in there, it's very hard to read (sorry)

I will try hyperv next. (Edit: doesn't work for other reasons)

I see the problem! The kubeadm config (which gets printed, so you can see it in the output), is this:

apiServer:
  certSANs: ["127.0.0.1", "localhost", ""]

And this seems where that empty string is coming from. To me it seems like it's reading from some kind of environment variable.

I think it wants to put the hostname there.

[MixusMinimax]

Still no idea how to fix this though, as this config is not written by me

Wait so are you starting up minikube yourself before installing the terraform config? the terraform config will try to create a new minikube instance which will fail if you already have one running as far as i can remember.

In the documentation https://github.com/eclipsesource/theia-cloud/blob/main/terraform/terraform.md it says this:

Then download the minikube virtualbox driver before invoking terraform:

minikube start --vm=true --driver=virtualbox --download-only

I missed the --download-only part (or just didn't put one and one together), so I was under the impression that I should start the cluster myself. The confusing part was that I did it that way on another pc. Thanks for the help!
