Sometimes I have to compile a binary or build a custom package on an old platform or an operating system where I don’t have a compile host available. Docker is a perfect tool for this type of ad-hoc workflow.
docker run --rm -it -v $(pwd):/mnt ubuntu:bionic
sed -i 's/^# deb-src/deb-src/' /etc/apt/sources.list
apt-get update
apt-get -y install dpkg-dev libssl-dev # any other dependencies
cd
apt-get source source-package-here
# cd into package and compile/make/build/etc
strip resulting_binary
cp resulting_binary /mnt
exit
This mounts the current directory at the /mnt mount point in the
container. The resulting artifacts (binaries, packages, etc.) can be
preserved by copying them out of the container before exiting.
