Happy new year from all of us in releng! Here’s a quick rundown of what’s happened over the holidays.

Modernize infrastructure:

We are now running 100% of our Windows builds (including try) in AWS. This greatly improves the scalability of our Windows build infrastructure. It turns out these AWS instances are also much faster than the in-house hardware we were using previously. On AWS, we save over 45 minutes per try run on Windows, with more modest improvements on the integration branches. Thanks to Rob, Mark, and Q for making this happen!

Dustin added a UI frontend to the TaskCluster “secrets” service and landed numerous fixes to it and to the hooks service.

Rob implemented some adjustments to 2008 userdata in cloud-tools that allow us to re-enable puppetisation of 2008 golden AMIs.

Callek added buildbot master configuration that enables parallel t-w732 testing prototype instances in EC2. This is an important step as we try to virtualize more of our testing infrastructure to reduce our maintenance burden and improve burst capacity.

Q implemented a working mechanism for building Windows 7/10 cloud instance AMIs that behave as other EC2 Windows instances (EC2Config, Sysprep, etc) and can be configured for test duty.

Mark landed Puppet code for base Windows 7 support including secrets and ssh keys management.

Improve CI pipeline:

Dustin completed modifications to the docker worker to support “coalescing”, the successor to what is now known as queue collapsing or BuildRequest merging.

Release:

Ben modernized Balrog’s toolchain, including switching it from Vagrant to Docker, enabling us to start looking at a more modern deployment strategy.

Operational:

Hal introduced the team learned about Lean Coffee at Mozlando. The team has adopted it wholeheartedly, and is using it for both project and team meetings with success. We’re using Trello for virtual post-it notes in vidyo meetings.

Rob fixed a problem where our AWS instances in us-west-2 were pulling mercurial bundles from us-east-1. This saves us a little bit of money every month in transfer costs between AWS regions. (bug 1232501)

See you all next week!
