Script that checks exposed Docker ports

I made a simple script that you can run and make sure what port
mappings you have and check if they are exposed.

Thanks for sharing! But why the need for a script for this? It can be
done with a single command directly:

 docker ps --format '{{.Names}}\t{{.Ports}}'

For the basic output. And if you dont want the containers listed that
dont have any mapped ports, i guess those are easily excluded with awk
or something. Once you have the json output from docker you can do
almost anything with it.

And then turn that into a alias in .bashrc for example.

Yeah, that what happens when you try to learn something new and rely
on ChatGPT too much :D

I will fix everything accordingly so it would at least output
everything in a better way.

I honestly hate it when people try to learn things from 0 to 100 based
on ChatGPT or any other AI stuff.  Current AI is very
/r/confidentlyincorrect

And you only waste your own time with it, and then further on the time
of other people who are trying to fix the AI mistakes. Everyone is
better off by not using the AI from the start.

So why would I use this instead of just running `docker ps -a` and
checking the port mappings from there?

Don't need the -a.

Ridiculous that this is being down voted.
