ngrok DNS headaches

Let’s not bury the lede: it was DNS. However, unlike the meme ("It’s not DNS, it’s never DNS. It was DNS"), I didn’t even have an inkling that DNS might be the problem.

I’m writing a new blog about streaming Apache Kafka data to Apache Iceberg and wanted to provision a local Kafka cluster to pull data from remotely. I got this working nicely just last year using ngrok to expose the broker to the interwebz, so figured I’d use this again. Simple, right?

Nope.
