MDN Web Docs Infrastructure scripts and configuration

MDN Web Docs infrastructure

This repo is maintained by the MDN Web Docs operations team, which includes MDN developers, Mozilla IT, and Mozilla Marketing Engineering and Operations (MozMEAO) site reliability engineers (SREs).

It was originally established and maintained by MozMEAO during the AWS update in 2017-2018. In 2018, MDN engineering moved to Emerging Technologies, and this repo was forked from mozmeao/infra to the MDN org.

How we manage our work

Our goal is to use the same principle as open source development for infrastructure management. We try to keep the planning, discussions, code, documentation, and processes open to the community. Operational access is limited to staff, but working in the open allows more staff members to take on tasks, and helps new staff get up to speed quickly.

Some data, such as API keys, are sensitive. These items are stored elsewhere and applied in production. Sensitive issues are discussed in confidential Bugzilla issues.

The MDN team uses 3-week sprints to break up work into manageable milestones. The MDN team work is tracked in GitHub issues and milestones using ZenHub. See the sprints wiki for more information.
