Hi all,  
how can I run a logstash container with a custom pattern folder?  
the patterns folder is in the /pipeline folder together with pipeline config

As long as the directory with the pattern files is made available to the Docker container it's no different from using a custom pattern directory with a Logstash _not_ running in a Docker container.

That does not help really. I have a pipeline folder wich contains:  
filter.conf input.conf output.conf /patterns

In my filter.conf I have set patterns\_dir =\> ["./patterns"], when I start the container with  
docker run --rm -it -v ./pipeline/:/usr/share/logstash/pipeline/ --name logstash [docker.elastic.co/logstash/logstash-oss:6.3.0](http://docker.elastic.co/logstash/logstash-oss:6.3.0) I get an error that pattern xyz (which is in the pattern dir) is not defined so the pattern dir is ignored

I always recommend using absolute paths (regardless of whether you're running Logstash in a Docker container). If that for some reason doesn't work you can try using the `-w` to set the working directory when starting the container. Of course, if Logstash itself changes its working directory it won't make a difference.
