switch to Invicton-Labs/terraform-external-shell-resource about terraform-openstack-rke2

That didn't work, but it did give me the solution. Documenting here incase someone else runs into it.

Just changing the output.

# Example 
module.test.module.controlplane.module.host[0].null_resource.shell: Destroying... [id=7139279717175408238]
╷
│ Error: Missing map element
│
│   on .terraform/modules/test.controlplane.client_certificate/main.tf line 125, in resource "null_resource" "shell":
│  125:       self.triggers.uuid,
│     ├────────────────
│     │ self.triggers is map of string with 12 elements
│
│ This map does not have an element with the key "uuid".

But just removing the affected state directly did work. Then changing the output_kubernetes_config back to true and it was recreated correctly.

# example
tf state rm 'module.test.module.controlplane.module.client_key[0].null_resource.shell'
Removed module.test.module.controlplane.module.client_key[0].null_resource.shell
Successfully removed 1 resource instance(s).

As always, thanks for the quick reply!

So @remche, I'm a little late to the party with this issue. Have you attempted an in-place upgrade?

The state blows up when applied. It wants to recreate the resources and then blows up in the process.

Are you aware of a process to upgrade an existing state to the new module?

[remche]

@powellchristoph could you try to upgrade with output_kubernetes_config = false before adding it again ?

[remche]

@powellchristoph thanks for documenting the issue. Let's pin it in for a while !
