Unexpected EOF

Description

Since some weeks use this provider to solve CRD Updates for the kube-prometheus-stack. The most time it works well, but some times we run into following issue at the terraform plan/apply :

    Error: Plugin error
    
      with module.prometheus-operator.kubectl_manifest.crd_alertmanagers,
      on .terraform/modules/prometheus-operator/crds.tf line 17, in resource "kubectl_manifest" "crd_alertmanagers":
      17: resource "kubectl_manifest" "crd_alertmanagers" {
    
    The plugin returned an unexpected error from
    plugin.(*GRPCProvider).UpgradeResourceState: rpc error: code = Internal desc
    = unexpected EOF

Unfortunately even with TF_LOG=DEBUG i dont get more information than this. The crds are relativley big with up to 5K Lines. Any idea what could lead to this issue?

Environment

Terraform v1.0.5 on darwin_amd64

• provider registry.terraform.io/gavinbunney/kubectl v1.13.1

Hey @steveizzle ,

could you maybe let us know how you are pushing this files via kubectl e.g provide all them at once and then use for_each or individual files?

One issue may be this: https://github.com/prometheus-community/helm-charts/blob/main/charts/kube-prometheus-stack/crds/crd-probes.yaml#L3 -- try to remove it (as that is needed when splitting manifest when you apply them all at once) and see if that will resolve the issue.

Best,

Hey i did that directly with individual files and without for_each like:

resource "kubectl_manifest" "crd_podmonitors" {
    yaml_body = file("${local.crd_path}/podmonitors.yaml")
}

i use the crds from the prometheus-operator (https://raw.githubusercontent.com/prometheus-operator/prometheus-operator/v0.52.0/example/prometheus-operator-crd/monitoring.coreos.com_alertmanagerconfigs.yaml) and removed the "---", but that didnt solve the problem unfortunately

I am experiencing exactly the same issue, as mentioned in the issue this only happens sporadically and the error can occur on any of the CRDs. We are using a for each loop that reads the CRDs form a crd sub folder in the module. For reference line "---" has been removed from each CRD.

resource "kubectl_manifest" "crds" {
  for_each = var.skip_crds ? {} : local.crd_files

  yaml_body = file(each.value)

  server_side_apply = true
  wait              = true
}

locals.tf

crd_files           = { for x in fileset(path.module, "crds/*.yaml") : basename(x) => "${path.module}/${x}" }
