Digger is an open source tool that helps you run Terraform in the CI system you already have, such as GitHub Actions. 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 and takes care of the other bits - locks, plan artifacts and so on. Features

Runner-less. Terraform runs in the compute environment of your existing CI such as Github Actions, Gitlab, Argo etc. Minimal / no backend. Digger's own backend is a serverless function; it is only needed for certain CI environments (eg Gitlab) Code-level locks. Avoid race conditions across multiple PRs. Similar to Atlantis workflow. Multi-cloud. At the moment Digger supports AWS and GCP; Azure support coming in April 2023 (yes, in a few weeks). Projects. Allow to isolate terraform runs and locks to a specific directory Terragrunt support Workspaces support
