Logstash docker pipeline volume not mounting

[iEMH]

Hi,
I am hoping someone can help me spot where am I doing a mistake.
I am trying to spin up a simple logstash docker container (oss) with a persistent volume mounted to the default pipeline directory.
However, when I look into the container, I see it only has the default *.conf file in the pipeline directory.

This is my docker-compose:

version: '3'
services:

  logstash:
      image: docker.elastic.co/logstash/logstash-oss:6.6.2
      container_name: logstash
      volumes:
         - lspipeline:/usr/share/logstash/pipeline
     ports:
         - 9600:9600
         - 5040:5040
         - 8181:8181
     networks:
         - esnet

  volumes:
      lspipeline:
  networks:
      esnet:

I can see that logstash starts up using only the default pipeline:

Login into the container and listing the contents of the pipeline directory (/usr/share/logstash/pipeline):

> bash-4.2$ ls pipeline/
> logstash.conf
> bash-4.2$ 

Inspecting the container, I see the mount is there.
But my mounted pipeline directory has three pipeline configurations. (no logstash.conf)

I also have an elasticsearch container with a mounted data directory, and that works fine. Also have one with red node, working fine as well. Only logstash seems to be a problem.

I cannot figure it out. Help please! Thanks!
