This repo contains the Dockerfile used to build the Datadog Agent (https://github.com/DataDog/dd-agent).
The Datadog Agent is built using a Chef omnibus project (https://github.com/DataDog/dd-agent-omnibus) on CircleCi.
The base image of the container is a homemade i386 image of Debian Squeeze.
To build this base image on a Debian based OS:
sudo apt-get install debootstrap
wget https://raw.githubusercontent.com/docker/docker/master/contrib/mkimage-debootstrap.sh
chmod +x mkimage-debootstrap.sh
./mkimage-debootstrap.sh -a i386 -t squeeze-386.tar.xz squeeze http://http.debian.net/debian
docker build -t datadog/debian-i386:squeeze -f Dockerfile-debian-i386 .
docker push datadog/debian-i386:squeeze
