dockerfiles's Introduction

Dockerfiles

Finally, Dockerfiles!

Build Patterns

The recommendation is to use multistage builds and, apparently, they're now supported on the Docker Hub! But, you might still find a reason to write a goofy single-stage build.

apt-get

I forget where I first saw this pattern, but the idea is to install all of the packages, including dev/build packages, do the work, then mark all of the unnecessary packages as purgeable.

RUN apt-get update \
    && apt-get install -y --no-install-recommends \
        foo \
        bar \
        baz \
    && ... build commands... 
    && apt-mark auto '.*' > /dev/null \
    && apt-mark manual "bar" \
    && apt-get purge -y --auto-remove -o APT::AutoRemove::RecommendsImportant=false \
    && rm -fr /var/cache/apt/* /var/lib/apt/lists/*

apk

TBD!

Postgresql-autodoc build from source

afl-fuzz

Try FROM scratch or alpine

Build w/ checkinstall

Oooh

https://wiki.debian.org/CheckInstall

git-vanity-sha

Try a Debian image

Maybe one of the Debian "slim" images will work?

With this in the Dockerfile
