Exception starting fscrawler in docker-compose

[cwperry]

I'm new to this project, and I'm trying to fire it up using docker-compose using the instructions in the docs. After bringing up the elasticsearch container, I try to bring up the fscrawler container and I receive the following message:

docker-compose up fscrawler

Here's my compose file, copied from the docs and modified for my index and source directory:

version: '3'

Any help would be greatly appreciated.

Thanks,

That's a bug. Have a look at #1229.

Thank you. To test fscrawler, so I need to back down to version 2.6?

[dadoonet]

I think that it works well without Docker. So if you have a JVM, just download fscrawler and launch it from your machine

Ok. Thanks.
