[Nifi] How to process to provide a user a FTP server

[#1]

Hi,

 I would like to know if it's possible to provide a FTP server via Nifi where a user could put files that can be then treated in Nifi. 
I saw the ListenFTP processor and i think i can do that with it but I don't really know how to set it up.
How will the user proceed to send his files?

I would like to try to set up this service locally first, knowing that Nifi runs with a docker-compose file.
Should I bring a special configuration in this case ?

I did not find any example on internet, hope you could help me.

@azg ,

Yes, you can do this with the ListenFTP processor.

Please take a look at the documentation pages below. They explain quite clearly how this processor works.

Thanks for your reply @araujo .
Indeed, the documentation explain well how to set it up. I just was wondering how to do it with docker-compose (i just recently introduce that technology). 

I only had to change the docker-compose.yml and adding the listening ftp port to the ports line :

  nifi:
    image: apache/nifi:latest
    ports:
      - "8443:8443"
      - "2221:2221"     <---- here
    volumes:
      - /home/user/nifi/datafiles:/data
      - /home/user/local-nifi:/local-data
    environment:
      - SINGLE_USER_CREDENTIALS_PASSWORD=
      - SINGLE_USER_CREDENTIALS_USERNAME=

Then i connected to it via FileZilla through `ftp://localhost` `port: 2221` and was able to transfer files.
