LogStash on Docker keeps shutting down after failing to find config

[rvshchwl (Ravish Chawla)]

I was running LogStash on Docker using the provided command, and today it crashed. After restarting the Docker, the Logstash silently shuts down after a few minutes, each time.

This is my starting script:

#!/bin/bash
docker run -d --name logstash \
--link elasticsearch:es \
-p 9997:9997 \
-p 9998:9998 \
-p 9999:9999/udp \
-p 9600:9600 \
-v /home/user/elk/:/usr/share/logstash/pipeline/ \
--net elasticsearch_default \
docker.elastic.co/logstash/logstash:7.4.0

And after I run it, my docker logs show the following:

[2019-10-25T05:39:48,023][INFO ][logstash.config.source.local.configpathloader] No config files found in path {:path=>"/usr/share/logstash/pipeline/*"}

I looked at a lot of different posts, and it looks like /usr/share/logstash/pipeline is the right location for the config file, but it doesn't look like its opened correctly. What is the right fix here?
