About Digger

• Unlike application code, terraform code has state. This makes CI/CD for it painful
• You could use a dedicated CI like Terraform Cloud or Atlantis, known as TACOs
• But then you end up duplicating your CI/CD infrastructure - compute, jobs, logs etc
• And you need to give it admin access to your cloud accounts

​

Run Terraform in your CI

Digger spins up jobs in your existing CI instead of running its own CI-like infrastructure. This is:

• More scalable, because the on-demand compute of your CI is reused
• More secure, because your sensitive data never leaves the CI job

​

Compared to Atlantis

• No need to host and maintain a server
• Secure by design
• Scalable compute with jobs isolation
• Role-based access control via OPA

Compared to Terraform Cloud and other TACOs

• Open source
• No duplication of the CI/CD stack
• Secrets not shared with a third party
