Filebeat.autodiscover seems to cause terraform/kubernetes based deploy issues

cgutshall · January 10, 2020, 9:02pm

I wrote up a yml based deploy to handle added a filebeat pod to each node in our EKS Cluster. When deploying the following config the pods are up and running with logs getting sent to elasticsearch.

kube_filebeat.yml

apiVersion: v1
    kind: ConfigMap
    metadata:
      name: filebeat-config
      namespace: kube-system
      labels:
        k8s-app: filebeat
    data:
      filebeat.yml: |-
        filebeat.autodiscover:

However I went to re-implement this with Terraform, for which I have the following two files. One to deploy the configmap.

main.tf

provider "kubernetes" {}
resource "kubernetes_config_map" "filebeat-config" {
  metadata {
    name      = "filebeat-config"
    namespace = "kube-system"
    labels = {
      k8s-apps = "filebeat"
    }
  }

And a the contents of the config file is pointing to.

filebeat.yml

filebeat.autodiscover:
  providers:
    - type: kubernetes
      host: ${NODE_NAME}
      hints.enabled: true
      hints.default_config:
        type: container
        paths:
          - /var/log/containers/*${data.kubernetes.container.id}.log

Using the terraform deploy causes the pods to crash with the following error:

2020-01-10T18:20:49.260Z	ERROR	instance/beat.go:916	Exiting: error in autodiscover provider settings: error setting up kubernetes autodiscover provider: unable to build kube config due to error: invalid configuration: no configuration has been provided
Exiting: error in autodiscover provider settings: error setting up kubernetes autodiscover provider: unable to build kube config due to error: invalid configuration: no configuration has been provided

Are there any thoughts as to why this would occur? It only seems to be an issue when using the filebeat.autodiscover module.

Thanks
