It works for me, but i'm wondering how it could be launched from cisco website when student start an exam. Probably the container should also include firefox because the container PT fails to be launched if firefox is on the host, i don't understand exactly why yet i made a link (ln -s) between /usr/local/bin/packettracer and your script but i'm not sure this the right way because probably it directly needs a binary and not script ... can you comment on that ?

I also added libqt5designer5 and libicu52 libraries and succeeded to launch the newpackettracer version 7.1 from your container ... however i have not tested it thoroughly so i'm not sure that everything works, ...

Hi, i'm new in docker, how do i run the PT after i create Dockerfile and packettracer7.sh.
Should i docker-compose and what is the command to run the PT.

Hope you can help me.
Thanks
