Atlantis CICD: Replacing Jenkins for Infrastructure Deployments
The presentation introduces Atlantis, a new automation tool designed for teams to collaborate on Terraform code, aiming to replace Jenkins for infrastructure deployments. Atlantis addresses the speed and complexity issues of the current pipeline. The current pipeline is practically very slow due to significant initialization time, multiple code cloning, sequential testing, and ECS deployer provisioning. The existing pipeline's complexity stems from continuous tweaking to integrate more features and cover edge cases, leading to fragility and drift.
Atlantis is standalone, self-hosted, free, and open source, with an active community. It offers a better collaboration model, simplified networking, and cost savings by removing the need for numerous VPC endpoints. Atlantis applies changes before merging, ensuring code in sync with infrastructure. The workflow is simplified, allowing direct communication with Atlantis from GitHub via comments on pull requests, eliminating the need for separate accounts and integrations.
Atlantis is hosted on a single EC2 instance in each landing zone's shared account, notified by GitHub Enterprise using webhooks. It uses service accounts to interact with GitHub, post comments, do merges, and close PRs. Cross-account access is managed through deployed key roles in each account, utilized for both simple and cross-account module deployments. User management is controlled on GitHub, and build logs are stored in comments for auditing. Atlantis enforces apply requirements, such as mergeability and peer approval, before applying changes. Auto-merge is enabled for automatic merging upon successful application. Parallel builds are supported, running plan and apply commands concurrently for multiple modules.
Atlantis locking prevents conflicts by locking the directory of each module when a plan is run, until the pull request is merged, closed, or the plan is discarded. When a plan is run, the directory of each module is locked until the pull request that is that has this folder locked is merged or closed, or the plan is manually discarded. Modules and data file dependencies can be declared to trigger plans when dependencies change. Documentation, troubleshooting guides, and a list of migrated repositories are available to assist users.
