Docker image of FreeNGINX

[Kacper Paczos]

I use nginx in my work, I use nginx Docker images. If I have a freenignx 
Docker image, I will switch to it.

I think the best option would be maximum compatibility, supporting the 
same tags and platforms as nginx. I believe this will help in gaining 
popularity for freenginx and will facilitate its adoption in production 
environments.

Please, let me know what you think about it. Next week, I will create an 
example Docker image for freenginx and send it here.

Happy Hacking!
