> My first attempt uses the small alpine image, which already packages thttpd:

  # Install thttpd
  RUN apk add thttpd

Wouldn't you want to use the --no-cache option with apk, e.g.:

  RUN apk add --no-cache thttpd

It seems to slightly help with the container size:

  REPOSITORY       TAG       IMAGE ID       CREATED          SIZE
  thttpd-nocache   latest    4a5a1877de5d   7 seconds ago    5.79MB
  thttpd-regular   latest    655febf218ff   41 seconds ago   7.78MB

It's a bit like cleaning up after yourself with apt based container builds as well, for example (although this might not always be necessary):

  # Apache web server
  RUN apt-get update && apt-get install -y apache2 libapache2-mod-security2 && apt-get clean && rm -rf /var/lib/apt/lists /var/cache/apt/archives

But hey, that's an interesting goal to pursue! Even though personally i just gave up on Alpine and similar slim solutions and decided to just base all my containers on Ubuntu instead: https://blog.kronis.dev/articles/using-ubuntu-as-the-base-fo...
