Distcc server images

I use this image to build distributed from my laptop when I don't want to wait.

This article by Konrad Kleine about compiling with distcc containers is a great place to start:

Quickstart

This section is mostly written for myself but I hope you will find it useful.

Build Docker Image

Since I only infrequently use this, it is simpler to just build it on the machine where I want to run it.

Download the sourcecode from this repository. Unzip the folder.

cd ~/Downloads/distcc-docker-images-*
docker build -t fedora## .

Replace ## with the fedora version of the base image

Run Docker image

docker run -p 3632:3632 -p 3633:3633 fedora## --allow 0.0.0.0/0

Replace ## with whatever you used when creating the image

Set up build host

export DISTCC_HOSTS='localhost/jobs hostname:3632/jobs'

Replace jobs with a number, indicating the max number of jobs to run on that host.

This can also be saved to /etc/distcc/hosts

Build

make -j32 CC="distcc gcc" [target]

Replace [target] with the desired target

Pro tip: Put time first to see how much faster you're building now!
