Added DeckTape Docker printing instructions to README

[mtoohey31]

Feel free to make changes if you'd like, I think the instructions are reasonably clear though.

Thanks @Ninja73737!

When I try it, I get this:

 ❯ ./bin/reveal-md.js demo/a.md 
Reveal-server started at http://localhost:1948

❯ docker run --rm -t --net=host -v foo:/slides astefanutti/decktape http://localhost:1948/a.md a.pdf
Loading page http://localhost:1948/a.md ...

Unable to load resource from URL: http://localhost:1948/a.md

Error: net::ERR_CONNECTION_REFUSED at http://localhost:1948/a.md

Am I missing something?

[mtoohey31]

Hmm that's odd... It appears correct to me, is http://localhost:1948/a.md the full url though or is there a #/ ending when you view it in your browser? That's the only thing I can think of, cause it looks like a networking issue, but you've used --net=host so the only thing I can think of is the url...

When I add the hash it's stripped off anyway:

❯ docker run --rm -t --net=host -v foo:/slides astefanutti/decktape http://localhost:1948/a.md#/ a.pdf
Loading page http://localhost:1948/a.md#/ ...

Unable to load resource from URL: http://localhost:1948/a.md

Error: net::ERR_CONNECTION_REFUSED at http://localhost:1948/a.md#/

Sorry, I'm not a Docker expert :)

[mtoohey31]

No worries, neither am I. I don't have access to a computer where I can run docker rn, so I can't troubleshoot, on Monday I should be able to though.

If you want to in the meantime though you could see if the issue still happens when you're running reveal-md through Docker too.

[mtoohey31]

Figured it out! The issue is that you can't use the localhost portion of the URL when you're running DeckTape from Docker and reveal-md locally, not in Docker. There are no issues when reveal-md is also running in Docker. I also checked whether or not the --host arg matters for reveal-md, and it doesn't seem to make a difference, so I added an edit to the pull request suggesting that users change the localhost portion of the URL to the IP address of their computer when running DeckTape in Docker and reveal-md locally.

Let me know if there's any other issues you run into!

Thank you, @Ninja73737! Works like a charm. I'm sure it will help folks out 👍

By the way, I did refactor the text a little bit, hope you are OK with it :)

Great, glad to help! And definitely no problem with changing the wording!
