Atlantis is a popular open-source tool that automates Terraform via pull request comments in GitHub, GitLab and Bitbucket. Setting it up correctly means writing a server config, a repo-level atlantis.yaml, and the right workflow steps for plan and apply, plus wiring authentication and webhooks. The moving parts are numerous, and a small mistake in the repo config can leave plans running against the wrong directory or workspace, or approvals misapplied to the wrong environment entirely without anyone noticing until it is too late.
The Terraform Atlantis Pipeline Generator builds those configuration files for you. Tell it your VCS, the workflow steps you want, whether to use workspaces, and how to authenticate, and the tool emits a server config and a matching atlantis.yaml. It follows Atlantis conventions for project layout, autoplan, and workflow naming, so the output is close to runnable. Everything is generated in your browser with no upload and no connection to your VCS, keeping tokens and repo details private while you design the integration and iterate on it locally first.
Use it to bootstrap a new Atlantis install, to standardise repo configs across many repositories, or to produce a review-ready starting point your platform team can harden with secrets and policies before it goes live in production.
Because the output is plain text, your platform team can review the generated configuration in the same pull request as the modules it manages, keeping infrastructure automation and the code it runs side by side under the same review process and approval rules.
