I am new to docker, and i have a project where i have to create containers for ethereum, bitcoin and iota, open ports for them and monitor the traffic with wireshark. I am using ubuntu, and the latest version of docker, and i believe i managed to create the containers ( when i type docker info, i get all the containers ).
I need help with opening of the ports? How do i open them, which port, what is the command.
Any help would be greatly appreciated.
