[FEATURE REQUEST] Allow to save files about curl-docker HOT 8 CLOSED

from curl-docker.

thx for taking the time to raise an issue.

as an alternate approach, have you tried pipe redirection to save file from the docker run command ?

for example:

> docker run --rm curlimages/curl:7.67.0 https://www.google.com/humans.txt > humans.txt

would save a file to humans.txt onto the docker host.

otherwise you are attempting to save a file into the container itself eg. try ~/humans.txt which would save file to user directory (which you should have perms for) in that container ... you would then need to use docker cp to copy that file from the container to the host machine.

@xquery thanks for the feedback! :-)

Hmm, I never used > to save (big) files from curl. Maybe using VOLUMEs could be better as suggested by @dfandrich .

If you want, I'm ready to send a PR allowing to use VOLUMEs. :-)

unless I am missing something - I do not believe any additional work is required for using volumes as per @dfandrich example.

docker run -v /tmp:/tmp curlimages/curl:7.67.0 https://www.google.com/humans.txt --output /tmp/humans.txt

This nicely illustrates how curl downloads file which should exist in the host machine's /tmp directory.

Considering you have several options that work today I am going to close this issue.

Hi @xquery @silvioprog

docker run -v /tmp:/tmp curlimages/curl:7.67.0 https://www.google.com/humans.txt --output /tmp/humans.txt

Has something changed since you posted that, since it gives me the error too. (Permission denied).

from curl-docker.

no ... and defo nothing has changed with 7.67.0 (previous version) ... sounds like a perms issue with your mount (try a different dir then /tmp ... which might have some expectations).

from curl-docker.

@xquery Good advice, thanks!

from curl-docker.

Uhm, it gives me also the same error.

docker run -v $(pwd):/some-arbitary-mount-point -it curlimages/curl -L --output /some-arbitary-mount-point/test.tar "example.com/file.txt"
