Great idea.

To confirm, the next steps would be:

1. Test Dockerfile build for alpine and ubuntu
2. Push to Dockerhub
3. Link to supported Docker images in README.md

Sounds like a good path!

This should be all that's required to get this going, in theory. Could probably be optimized for size better still:

• https://github.com/alias1/docker-oxml_xxe/blob/master/Dockerfile

When running it, I seem to be unable to access the exposed port from my browser though. Wondering if there is some localhost type binding in the container that isn't playing nicely with things?

[Sinderella]

@alias1 I had a look at it. Webrick, by default, only serves on localhost. -o is required if you want to expose it to other network interface.

I don't know if it's a good idea to have it as 0.0.0.0, but I'll leave it for someone to decide. 😄

[0xdevalias]

Ah, that makes sense. Was thinking along similar lines, but thought docker's port mapping may have overcome it. I guess not.

[0xdevalias]

Updated my Dockerfile to include the above, seems to work now.

https://github.com/0xdevalias/docker-oxml_xxe/blob/ead927e072dbe49c78cba7355ec4a9e1ce3595d5/Dockerfile#L10-L11

It builds to ~200mb, could almost certainly optimize it since most of that weight seems to come from the apt-get installs, but not a high priority for me currently.

Thanks!! Added a docker directory with your code, I can take PRs into that if you want. Would be great to have this in master.
