    Surely this is ripped content?

      Yep, it’s also AI slop. @dang ?

    We had issues running our Node app on alpine. Specifically the dns lookup for our API calls were taking several hundred milliseconds *every* time.

    Switching to debian reduced it to microseconds.

    Does anyone here know what I was doing wrong with alpine?

      Alpine is a bad idea for a non-trivial application written in Python, Node.js, or any other interpreted language.

      Too many weird edge cases to deal with, especially related to Alpine using musl libc instead of glibc.

      At best, your builds are slower.

      At worst, certain code paths are broken.

        I had this experience as well, nowadays I use Debian slim. Too much random breakage in Alpine.

      Musl is much less optimized than glibc, random example: https://andygrove.io/2020/05/why-musl-extremely-slow/

    Good post. Using slim is the easiest and biggest impact change.

    Ditch docker and use Golang to bring it to 4MB.

      Ditch Golang and use a textfile containing the text "Hello world!" to bring it to 12 bytes.

        That's not going to work, that's a static file.

        Golang gives you a web server as a staticly linked binary.

          If we're disregarding requirements, I figured I'd disregard some too.

          If the question is "I need to containerize my Node app, how do I make it small?" the answer can't be "don't containerize it and don't use Node".
