Docker export and working directory about decktape HOT 7 CLOSED

The only way to achieve this that I know of is to run:

docker run --rm -v `pwd`:/pwd -w /pwd astefanutti/decktape http://remarkjs.com/ export.pdf

This will execute in the specified working directory /pwd, which is mounted to the current directory.

As documented in Mount a host directory as a data volume:

The host directory is, by its nature, host-dependent. For this reason, you can’t mount a host directory from Dockerfile because built images should be portable. A host directory wouldn’t be available on all potential hosts.

So this can't be totally defined in DeckTape Dockerfile and has to be specified on the command line by the end-user. Though we could define a default container working directory.

@astefanutti, your solution would be great!

Can you add the WORKDIR in the Dockerfile or do you prefer that I create a pull request?

@oupala, we could declare a default /slides working directory in the Dockerfile. The ENTRYPOINT would have to be updated to reference the absolute path of the decktape.js script.

You're welcome to create a PR. That'd be great if you could update the Docker instructions in the README file as well 😉.

I've just created a pull request #64. I let you rebuild the Dockerfile when the pull request is merged (unless this is done automatically on a git push event).
