10+Production deployment notes
13+In Launchpad's production build farm, launchpad-buildd is deployed via base
14+virtual machine images constructed by taking standard Ubuntu cloud images
15+and installing launchpad-buildd in them from
16+ This is done
19+(currently private, sorry).
21+At present (May 2020), all these base VM images are built from Ubuntu
22+xenial, and launchpad-buildd runs on Python 2. We plan to upgrade these to
23+bionic soon, where it will be possible for launchpad-buildd to run on Python
24+3; however, it's necessary to support the powerpc architecture until at
25+least April 2021 (end of standard maintenance for xenial), and the powerpc
26+base images will need to stay on xenial since that architecture is no longer
27+supported by bionic. As a result, launchpad-buildd must run on both Python
28+2 and 3 for the time being.
