Docker container: missing library for ftps

[Micsi]

Hi,

after establishing a working ftp connection, I wanted to switch to ftps for my docker setup. But the container does not start with the setting:

[global]
e2dsa # enable file indexing and filesystem scanning
e2ts # enable multimedia indexing
ansi # enable colors in log messages (both in logfiles and stdout)
ftps: 21
ftp-pr: 12000-12005
ftp-nat: 192.168.178.47

from the container log:

copyparty | ftps requires pyopenssl;
copyparty | please run the following:
copyparty |
copyparty | /usr/bin/python3 -m pip install --user pyopenssl
copyparty |

regards

Jochen

pyopenssl is not included in the minimal docker image, however it is included in all the other docker images; im, ac, iv, dj

I see! Thanks for clarification. I wondered, if it could be the image, but the docs do not mention that.What a shame, as I was looking for a lightweight sftp-server. So I would need sftp but have no use for the decoders included in the larger versions. But I understand, that‘s not the focus of this project.Best,JochenAm 04.12.2025 um 19:38 schrieb ed ***@***.***>: pyopenssl is not included in the minimal docker image, however it is included in all the other docker images; im, ac, iv, dj —Reply to this email directly, view it on GitHub, or unsubscribe.You are receiving this because you authored the thread.Message ID: ***@***.***>

ah, this is a good time to clarify that sftp is not the same thing as ftps;

ftps is ftp with tls encryption (similar to http and https), while sftp is something else entirely -- it is not at all related to ftp.

copyparty does not do sftp yet, but it will in a few months probably: #308

and the reason that ftps is disabled in the minimal container is because it's not a core feature, and ftps itself is not a small component, inflating the image by several megabytes. The size difference between min and im is 13 megabytes (57 vs 70).

ah, yes! You are right. And the naming is HORRIBLE. I too was speaking about ftp with tls, not the ftp-like protokoll over ssh.Especially this was the reason for me to seek a light docker Tool for some backup need, as I have ssh enabled servers about everywhere.Backup is not one of the main goals of your fabulous project right? So no reason to look for some sort of retention settings for a volume, right,I will switch to im then thanks, Best Jochen
