Uploading empty file: Permission denied about transfer.sh

[DrackThor]

Same problem here - I tried the simple example from the README.md docs:
image ID: 92f2b0b2f3ff

# started the container
docker run --publish 8080:8080 dutchcoders/transfer.sh:latest-noroot --provider local --basedir /tmp/

# tried to upload a random file
curl -v \
--upload-file ./README.md \
https://localhost:8080/README.md

CURL:

curl -v \
--upload-file ./README.md \
http://localhost:8080/README.md

I also tried the same thing with the :latest (root) image - this works fine.
So this very much looks like a -noroot image issue

thanks for the report, I'll check on it

I fixed the issues by mapping the volume from host to container.

Example: docker run --publish 8080:8080 --volume "./tmp:/data" dutchcoders/transfer.sh:latest-noroot --provider local --basedir "/data"

I've tried adding /tmp as volume, and now I get this error:

Could not upload empty file

Logfile says:

If you run as I posted, first, you must create a directory "tmp" in your current directory. My reply is just trying to explain that you need to make sure the directory exists in the container and you have mapped it on the host.

Good luck

I created the directory before and set the uid and gid both to 5000. Permission is 0775. I can upload any non-empty file. Except for empty files I got the mentioned error.

I think this is fine. Sharing empty files is a bit of useless, so this error don't need to be fixed. Besides, with this setup the error code changed from 500 to 400.
