Why This AMI Instead of Self-Deploying?
Atlantis is a popular open source server that automates OpenTofu and Terraform pull request workflows: it listens for webhooks from your Git provider and runs plan and apply on your pull requests, posting the plan output back to the PR and locking the workspace so two changes cannot touch the same state at once. Deploying it yourself means installing the binary, choosing and installing an infrastructure-as-code engine, writing systemd units, hardening a reverse proxy, generating secure passwords, and maintaining the stack. This AMI eliminates that effort - a pre-hardened Atlantis server is running within minutes of launch, backed by 24/7 expert support with a one-hour average response for critical issues.
OpenTofu Bundled, Not Terraform
This image ships the OpenTofu command-line engine (Mozilla Public License 2.0) and configures Atlantis to drive it. OpenTofu is a fully open source, drop-in replacement for Terraform. Terraform itself moved to the Business Source License in version 1.6, whose terms restrict competing hosted offerings, so this image deliberately bundles OpenTofu rather than a restrictively-licensed Terraform binary. If you prefer to run your own Terraform, you can install it and repoint the engine.
Secure By Default
Many pre-built images ship with shared or default passwords - a common vulnerability that exposes instances immediately after launch. This image eliminates that risk:
- A unique web password is generated for every instance on its first boot
- It is stored in a root-only file, inaccessible to unprivileged users
- The web UI is refused without credentials and reached only through an authenticated reverse proxy on port 80
- The application listens on loopback and is never exposed directly
- No shared or default password ships in the image
A continuous-delivery server that can run apply against your cloud is a high-value target, so access to the web UI is gated behind HTTP Basic authentication with the per-instance password.
You Connect Your Own Repositories
Atlantis orchestrates your infrastructure only after you connect it to your own version control. The image ships ready for you to add your GitHub, GitLab, Bitbucket or Azure DevOps credentials, webhook secret and repository allowlist in a single configuration file, then point a webhook from your repository at the instance. Until you do, the server runs and serves its dashboard but acts on no repository - nothing is automated behind your back. The user guide walks through connecting a repository step by step.
Proven Plan Engine
Every instance ships with a self-test that runs a real OpenTofu plan through the same engine Atlantis drives, proving the plan machinery works end to end before you ever connect a repository - not merely that a web page loads.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
Version release notes

Additional details
Usage instructions
Connect via SSH on port 22 as the default login user for your operating system variant (the user guide lists it per variant; on Ubuntu it is 'ubuntu'). The Atlantis web UI is served by nginx on port 80: browse to http://<instance-public-ip>/ and sign in as user 'admin'. Retrieve the generated web password with: sudo cat /root/atlantis-credentials.txt. Atlantis runs on loopback port 4141 and is reached only through the authenticated nginx proxy on port 80. To connect your repositories, edit /etc/atlantis/atlantis.env and set your VCS credentials (ATLANTIS_GH_USER, ATLANTIS_GH_TOKEN, ATLANTIS_GH_WEBHOOK_SECRET or the GitLab / Bitbucket / Azure DevOps equivalents), replace the deny-all ATLANTIS_REPO_ALLOWLIST with your own (for example github.com/your-org/*), then run: sudo systemctl restart atlantis. Add a webhook in your repository pointing at http://<instance-public-ip>/events (content type application/json, secret set to your webhook secret, events: pull requests, pushes, issue comments). The OpenTofu engine is bundled at /usr/local/bin/tofu and Atlantis is configured to drive it. The user guide covers first sign-in, connecting a Git provider, the plan round-trip self-test, and enabling HTTPS.
