The pinnacle of StackOverflow irony: your Docker localhost question is flagged as a duplicate of a post that's been closed for not being about programming, which has 5x more upvotes than the "correct" question. Meanwhile, both questions are closed for completely contradictory reasons.
It's like trying to exit Vim - no matter what you do, you're trapped in an endless cycle of "closed," "duplicate," and "not about programming" while desperately trying to figure out why your container can't see localhost. The cherry on top? The 2.8 million views suggest thousands of developers have the exact same "not programming related" problem.
