Filebeat setup without Kibana?

Working on a setup where log data is stored in elasticsearch using filebeat.

However, we don't need Kibana (lovely although it is) for this application. The data is queried separately via an API.

I read: Configure Kibana dashboard loading | Filebeat Reference [7.12] | Elastic

I also read How to run filebeat without Kibana? - #7 by Wahyu however that doesn't appear to fix the issue.

If I specify, in filebeat.yml

setup.dashboards.enabled: false

Then filebeat setup will still try to contact Kibana and error out.

|2021-05-03T09:48:43.520Z|INFO|kibana/client.go:119|Kibana url: http://localhost:5601|
|2021-05-03T09:48:43.521Z|ERROR|instance/beat.go:971|Exiting: error connecting to Kibana: fail to get the Kibana version: HTTP GET request to http://localhost:5601/api/status fails: fail to execute the HTTP GET request: Get http://localhost:5601/api/status: dial tcp connect: connection refused. Response: .|

I also tried replacing the kibana directory with an empty volume mount, but it has the same error.

  - './filebeat/filebeat.docker.yml:/usr/share/filebeat/filebeat.yml:ro'
  - './filebeat/kibana:/usr/share/filebeat/kibana'

Is there a way to disable Kibana loading in filebeat.yml ?
I still need to configure additional ILM options such as:

  overwrite: true
  enabled: auto
  rollover_alias: "metrics"
  pattern: "{now/M{yyyy.MM}}"

Maybe there's another way to apply ILM config, without running setup?

To answer my own question, it appears it's not necessary to run

filebeat setup

With the ILM config in filebeat.yml it is applied automatically

Seen in the following log:

@davidwhthomas A few different ways, just to add for others that might visit this later.

You should comment out the "setup.kibana" part of the filebeat.yml, since if you do not need to setup the dashboards then that part might as well be removed.

For the second part, it is possible to choose what part you want to setup, as referenced on the flag section here: Filebeat command reference | Filebeat Reference [7.12] | Elastic

So you could do filebeat setup --pipelines for example. You do want to apply at least the ILM (if needed) and the ingest pipelines if you are using modules.
