For me it's that the things I install are deliberate. I have to opt into installing every extra package, so I am more thoughtful in expanding the base image.

I liken it more to my fond days with FreeBSD and OpenBSD. A narrowly scoped base image and userland, but easy access to a vast array of packages/ports, but each explicitly listed and installed.

It's "batteries included" but "pick your batteries" vs "here's a kitchen sink full of batteries."

Running applications on Alpine feels like very deliberately building an environment, whether inside a container or directly on a host.

(Just be aware of the differences between glibc and musl... DNS resolution in particular will bite you if you don't understand the implementation)

Have any details about the DNS resolution stuff?

TL;DR musl attempts to query every resolver in parallel. This can cause problems if:

- If your resolvers are VIPs for the same process or machine, you can triple you DNS load and overload some crappy DNS dispatchers

- If you try to use multiple resolvers that resolve the same names with different records, you can kind of make it work with glibc but you will have severe problems with musl. This is a bad idea in the first place though
