Atlantis

Atlantis runs Terraform from pull requests: plan on the PR, apply from a comment after review, lock so two PRs cannot collide. This course covers the server and webhooks, atlantis.yaml projects, custom workflows, Conftest gates, and how to keep cloud credentials off the comment thread. The server holds apply rights; treating it like a dashboard is how people get surprised.
