Docker open Tomcat page from container running on virtualbox

hello everybody

I’am done the first paced training and i can’t open the web page tomcat serveur.

i am using virtualbox on my windows 7. i installed Ubuntuserver and Docker engine.
So when i using this command " Docker run -d -P tomcat;7" everything seems works
Result of command " docker ps "
tomcat:7 0.0.0.:32768->8080/tcp

so when i try to open on my webbrowser on my machine windows 7 myip:32768 and it’s not working

So what must i do ? configure iptables ?

thanks a lot

Well my host OS is Linux so maybe it’s a little different and I’m new to Docker but I start the tomcat example as follows:
docker run -it --rm -p 8888:8080 macedemo/tomcat

My docker ps looks totally different than yours:

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
e7e7720157ce macedemo/tomcat “catalina.sh run” 6 minutes ago Up 6 minutes 0.0.0.0:8888->8080/tcp prickly_nobel

But then again I followed this set of directions and did not pull/start directly from the hub. I wanted to work with a dockerfile and see how it worked.

Also looking at what you wrote are these typos?
"Docker run -d -P tomcat; " the “;” I think should be a “:”
"tomcat:7 0.0.0.:32768->8080/tcp " this does not look correct either. Should it not be 4 “0” not 3?

Just some thoughts.
