docker container crashes

[johanngb]

I run

docker run astefanutti/decktape http://lab.hakim.se/reveal-js slides.pdf

and get

(node:1) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): TypeError: Unable to create PDF file, make sure that output file target is available (node:1) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

I am on ubuntu 17.04. I have tried this on two different computers (both 17.04) and get the same error message. Happy to provide any other information that might be helpful.

Take a look at the README, you need to specify where to save the result:

$ docker run --rm -v `pwd`:/slides astefanutti/decktape http://lab.hakim.se/reveal-js slides.pdf

Thanks for the quick reply! I tried that first actually, and got the same error message. I thought maybe something was going wrong with accessing the host file system, so that's why I tried the "simpler" version (Bottom of readme, under "Alternatively, you can use the docker cp command.").

Is there any other variant that might make sense to try?

Ok I see. For me that's working fine.

[johanngb]

Interesting. I have a windows machine. I will install docker on there and try that out too, and let you know what happens.

[johanngb]

I got the same error when I tried it on windows. (Windows 10, fresh docker install). Are you using the most recent docker image? Thanks!

I'm also using Ubuntu 17.04 and it's working fine. You can also try earlier versions, e.g. 1.0.0 also works for me.

I've just fixed a permissioning issue with the /slides directory.

@johanngb could you please retry with the latest astefanutti/decktape image?

[johanngb]

Yes, it works now. Thank you so much!

Thanks for the feedback. Let me close this then.
