Remote access to webserver in docker container

Question

I\'ve started using docker for dev, with the following setup:

• Host machine - ubuntu server.
• Docker container - webapp w/ tomcat server (using https).<

Answer 1

I figured out what I missed, so here's a simple flow for accessing docker containers webapps from remote machines:

Step #1 : Bind physical host ports (e.g. 22, 443, 80, ...) to container's virtual ports. possible syntax:

    docker run -p 127.0.0.1:443:3444 -d 

(see docker docs for port redirection with all options)

Step #2 : Redirect host's physical port to container's allocated virtual port. possible (linux) syntax:

    iptables -t nat -A PREROUTING -i  -p tcp --dport  -j REDIRECT --to-port 

That should cover the basic use case.

Good luck!
