Multiple Mesos build configurations using Docker
I recently worked on a Mesos issue to improve build time. The idea was to use a tool that will help us remove unnecessary header inclusions.
One of the only tools available for this is Include-What-You-Use, it’s not a proclaimed 100% accurate tool but we had to give it a try since doing the same task manually can be a little repetitive.
Making a llvm clang plug-in work with Mesos was not obvious at first that’s why I had to try in an out of tree builds for Include-What-You-Use and multiple clang versions before finding the right combination.
To make this easier I begun creating a Mesos Docker image for developers that I recently pushed to their registry , there are Mesos Dockerfiles that can already be found in the registry but it was something new to learn, since I always built my Docker containers from command line with only base images and also there were any IWYU image available.
