lapax/tiny-mosquitto repository overview

this file is available at

https://github.com/lexlapax/Dockerfiles/blob/master/tiny-mosquitto/README.md⁠

currently uses http://mosquitto.org/files/source/mosquitto-1.2.3.tar.gz⁠

this is built using buildroot http://buildroot.uclibc.org/⁠ in order to make the image small.

the docker image was built with instructions from

http://blog.docker.io/2013/06/create-light-weight-docker-containers-buildroot/⁠

the buildroot directory contains the .config file used for running the build.

mosquitto uses malloc_usable_size which is not available in uclibc

the config uses glibc instead because of that

the buildroot/package/mosquitto contains the two required files to include mosquitto into the buildroot build

⁠short instructions

(the full instructions are in the buildimage.sh file)

download buildroot

git clone this repo

copy buildroot config and mosquitto build instructions from git clone to buildroot directory

build root image

touch up root image with docker support (/sbin/init and /etc/resolv.conf)

import image into docker (at this point the image can be tested)

create new image from Dockerfile

enjoy

the image built this way is tiny
