Not getting index with docker module

[Trung_Dam1 (Trung Dam)]

Hi everyone,
I am new to using elasticsearch
I have a problem with metricbeat specifically with the docker module
With the configuration as below I have renamed the index with the event.moudle field which will change the name to another index but, I am not getting any docker related index, I have enabled the moudle system and it works fine.
Can someone help me?

output.elasticsearch:
  # Array of hosts to connect to.
  hosts: ["10.10.1.13:9200"]
  indices:
    - index: "metricbeat-ipp-prod-worker1-metric-%{[agent.version]}-%{+yyyy.MM.dd}"
      when.equals:
        event.module: "system"
    - index: "metricbeat-ipp-prod-worker1-docker-%{[agent.version]}-%{+yyyy.MM.dd}"
      when.equals:
        event.module: "docker"
