> /srv/docker/logstash/etc:/config-dir : i don't understand the config-dir , i'm expecting a path not this The `-v /srv/docker/logstash/etc:/config-dir` option will cause the host path /srv/docker/logstash/etc to be available as /config-dir inside the container. > -f : i don't understanf the -f option why it's used The `-f` option and the pathname that follows are passed to Logstash. > **[Running Logstash from the Command Line | Logstash Reference \[8.11\] | Elastic](https://www.elastic.co/guide/en/logstash/current/running-logstash-command-line.html)** ---

It depends on the image you're using and how it invokes Logstash. ---
