CI/CD for Terraform is tricky. To make life easier, specialised CI systems aka TACOS exist - Terraform Cloud, Spacelift, Atlantis, etc.

But why have 2 CI systems? Why not reuse the async jobs infrastructure with compute, orchestration, logs, etc of your existing CI?

Digger runs terraform natively in your CI. This is:

• Secure, because cloud access secrets aren't shared with a third-party
• Cost-effective, because you are not paying for additional compute just to run your terraform

Features

• Terraform plan and apply in pull request comments
• Any VCS - Github, Gitlab, Azure Repos, etc
• Any CI - Github Actions, Gitlab, Azure DevOps, etc
• Any cloud provider - AWS, GCP, Azure
• Private runners - thanks to the fact that there are no separate runners! Your existing CI's compute environment is used
• Open Policy Agent (OPA) support for RBAC
• PR-level locks (on top of Terraform native state locks, similar to Atlantis) to avoid race conditions across multiple PRs
• Terragrunt, Workspaces, multiple Terraform versions, static analysis via Checkov, plan persistence, ...
• Drift detection - coming soon
• Cost estimation - coming soon

Getting Started

• Github Actions + AWS
• Github Actions + GCP
• Gitlab Pipelines + AWS
• Azure DevOps

How it works

Digger has 2 main components:

• CLI that runs inside your CI and calls terraform with the right arguments
• Orchestrator - a minimal backend (that can also be self-hosted) that triggers CI jobs in response to events such as PR comments

Digger also stores PR-level locks and plan cache in your cloud account (DynamoDB + S3 on AWS, equivalents in other cloud providers)
