Hi There, how to EXPOSE port on running container? Regards Asura

Hello Jeff, In case of “VNC” is running with session one on inside the container and one user working on his session. But, user two want work on the same container… how does it work’s in that time. when container it expose with only port or mention all will exposed… Every new VNC session having…

@girikumar Are you sure to using container with your way? Don’t think the container as a server.

Good Bill, There is the way from Docker, where we use “-P” (upper case “P”)to auto mapping to host from container. In that case, why can’t have option for auto EXPOSE. And there is option to expose port while starting the container. also… docker run -i --expose=22 b5593e60c33b bash if EXPOSE po…

then you can do the command with multiple -p options when run the image. docker run -d -p 5801:5801 -p 5802:5802 .....

yes… but my question is, inside container new port is enabled… how to forward that port, to access Regards Asura

Your better bet will probably be to simply create new containers for each time a new service is needed. All of your containers would have a vnc service running internally on the VNC port, and then you would allocate new ports each time you started a new server. docker run -d -p 5801:5800 --name vnc…

You cannot with pure Docker, but you could run a TCP proxy: docker run -ti --rm --net host bobrik/socat TCP4-LISTEN:9300 TCP4:172.17.0.3:9300 Will “open” port 9300 of container 172.17.0.3.

Or simply use linux builtins… iptables -t nat -A DOCKER -p tcp --dport 9300 -j DNAT --to-destination 172.17.0.3:9300

Hi,

The solution to mapping port while running the container.

docker run -d --net=host myvnc

that will expose and map the port automatically to your host

Thank you
