After 160 [work] days, 155 patches, and approximately 8,977 cups of coffee; I'm now wrapping up my third quarter with Mozilla -- the time has flown by! In these first eight months I've written some fun code, shaved enough yaks to knit new wool sweater, and become acquainted with the ghosts of Mozilla RelEng past, present, and future; to great effect.

Quarter one was spent getting familiar with Mozilla RelEng's legacy: re-writing/taking ownership of existing services like clobberer. The second was all about optimizing our existing infrastructure: principally by rolling out runner. Then, this one has been dedicated new beginnings: porting jobs from our old buildbot based CI infra to the shiny new TaskCluster based one.

In moving [Linux] jobs from buildbot to TaskCluster, I've worked on docker containers which will build Firefox with all of the special options that RelEng needs. This is really cool because it means developers can download our images and work within them as well, thus creating parity between our CI infrastructure and their local environments (making it easier to debug certain bugs). So, what's my status update?

The good news: the container for Linux64 jobs is in tree, and working for both Desktop and Android builds!

The better news: these new jobs are already working in the Try tree! They're hidden in treeherder, but you can reveal them with the little checkbox in the upper right hand corner of the screen. You can also just use this link: https://treeherder.mozilla.org/#/jobs?repo=try&exclusion_profile=false

# note: These are running alongside the old buildbot jobs for now, and hidden. The container is still changing a few times a week (sometimes breaking jobs), so the training wheels will stay on like this for a little while.

The best news: You can run the same job that the try server runs, in the same environment simply by installing docker and running the bash script below.

Bonus: A sister 32 bit container will be coming along shortly.
