- Version: 6.5.4
- Operating System: Running with Docker
- Config File:

pipelines.yml

```auto
- pipeline.id: test-app
   path.config: "pipeline/test-app-pipeline.conf"
- pipeline.id: test-app1
   path.config: "pipeline/test-app1-pipeline.conf"

```

- Error Message:  
`[2019-02-01T03:36:48,658][ERROR][logstash.config.sourceloader] Could not fetch all the sources {:exception=>LogStash::ConfigurationError, :message=>"Failed to read pipelines yaml file.

- Steps to Reproduce:  
I run Logstash docker image with config.reload.automatic set to true to leverage pipelines.yml file. **Everything works fine up to this point. The log files get parsed and indexed to Elasticsearch database, blah blah.** While Logstash is still up, I try to remove a pipeline from the pipelines.yml file. Logstash notices the changes but unable to reload. It produces the message above. The same thing happens when I try to add a pipeline to the pipelines.yml file (of course, I have added the pipeline conf file before doing this).

Also note that when I make changes to each individual pipeline's config files (test-app-pipeline.conf & test-app1-pipeline.conf), Logstash notices the changes and automatically reloads, and everything works perfectly fine. Only when I make changes to the pipelines.yml, I got this error.

I currently use docker compose to manage the containers (ES, Logstash, and Kibana). One of my goals is to **be able to dynamically add and remove pipelines while the whole stack is running**.  
Could anyone please give me some insight to this issue? I appreciate a lot.

I have found the solution.

Apparently when I edit pipelines.yml with pycharm, the bind-mounted file is corrupted and unable to read by the container. I realize this when I go into the container and try to cat the file. It gives me Input/Output Error. By following this thread I am now able to get it working.
