[Error] Logstash 8.11.3 pipeline.conf (logstash.conf) issue

[F9Alejandro]

When trying to run the logstash portion of the compose it throws an error about the formatting of the .conf file. I am using the file that is provided in this repo and haven't made any changes to it.

Logstash error:

Any recommendations for trying to fix this issue?

I've figured it out, logstash needs to know where is the pipeline .conf file, relevant part from docker-compose.yml:

  logstash01:
    depends_on:
      es01:
        condition: service_healthy
      kibana:
        condition: service_healthy
    image: docker.elastic.co/logstash/logstash:${STACK_VERSION}
    labels:
      co.elastic.logs/module: logstash
    user: root
    volumes:
      - certs:/usr/share/logstash/certs
      - logstashdata01:/usr/share/logstash/data
      - "./logstash_ingest_data/:/usr/share/logstash/ingest_data/"
      - "./logstash.conf:/usr/share/logstash/pipeline/logstash.conf:ro"
    environment:
      - xpack.monitoring.enabled=false
      - ELASTIC_USER=elastic
      - ELASTIC_PASSWORD=${ELASTIC_PASSWORD}
      - ELASTIC_HOSTS=https://es01:9200
    command:
      - -f
      - /usr/share/logstash/pipeline/

Add the command part to the code.

thanks for the heads up. i'll test the one out.

i am unable to recreate this error and do not need to specify the -f command as this is taken care of by passing in the logstash.conf to the default pipeline directory.

@elkninja probably because this issue is related to version 8.11.3 and above. I had the same error message with 8.12.0.
