How to start and interact with the default command on a container using the "docker container start --interactive" command?

The "docker container start --attach --interactive" allows you to start the default command with the hosting console attached to the TTY terminal of the default command.

The "--interactive" option is needed, so that your console can interact with the running program.

1. Create a new container with a TTY terminal in interactive mode:

fyicenter$ docker container create --name java --tty --interactive openjdk

2. Start the container with the console attached to the TTY terminal and interact with the default command.

fyicenter$ docker container start --attach --interactive java

java.util.prefs.FileSystemPreferences$1 run
INFO: Created user preferences directory.
|  Welcome to JShell -- Version 12.0.1
|  For an introduction type: /help intro

jshell> 1+2;
fyicenter$1 ==> 3

jshell> /exit
|  Goodbye

As you can see, we are able to create a container with TTY terminal to its default command "jshell" from the "openjdk" image. And we can run it interactively from the hosting console.
