Filebeat not adding kubernetes metadata

[jaininshah9]

I am running a Kubernetes (v1.12.3) cluster and trying to use filebeat to get the data from docker containers. The logs works fine (for testing purpose I am sending it to just files), but there is no kubernetes metadata coming through. Here is my config, not sure what I am doing wrong.

Any help would be appreciated! Thank you!

filebeat.yaml

filebeat.config:
  inputs:
    # Mounted `filebeat-inputs` configmap:
    path: /root/filebeat-6.5.4-linux-x86_64/inputs.d/*.yml
    # Reload inputs configs as they change:
    reload.enabled: false
  modules:
    path: /root/filebeat-6.5.4-linux-x86_64/modules.d/*.yml
    # Reload module configs as they change:
    reload.enabled: false

# To enable hints based autodiscover, remove `filebeat.config.inputs` configuration and uncomment this:
#filebeat.autodiscover:
#  providers:
#    - type: kubernetes
#      hints.enabled: true

output.file:
  path: "/tmp/filebeat"
  filename: filebeat
  #rotate_every_kb: 10000
  #number_of_files: 7
  #permissions: 0600
