Terraform

Terraform enables you to safely and predictably create, change, and improve infrastructure.

The easy_infra project includes and secures Terraform as a component due to its popularity and versitility in provisioning and updating environments as Infrastructure as Code (IaC).

easy_infra’s Terraform security uses tools such as KICS, Checkov, tfsec, and Terrascan to semi-transparently assess the provided IaC against the defined security policy.

Terraform security is included in all of the easy_infra tags, including minimal, aws, az, and latest

Use Cases

If you use Software Version Control (such as git) to manage your Terraform IaC, consider executing terraform validate with easy_infra as a pipeline action on commit or pull request:

docker run -v $(pwd):/iac seiso/easy_infra:latest-minimal terraform validate

You can also use easy_infra to deploy your infrastructure using terraform plan and terraform deploy:

docker run -v $(pwd):/iac seiso/easy_infra:latest-minimal /bin/bash -c "terraform plan && terraform apply -auto-approve"

Terraform Caching

If you’re working with the same terraform code across multiple runs, you can leverage the cache:

docker run -v $(pwd):/iac -v $(pwd)/plugin-cache:/home/easy_infra/.terraform.d/plugin-cache easy_infra:latest-minimal /bin/bash -c "terraform init; terraform validate"

Resources

Configuring custom checks can be done by leveragin the robust Rego language, maintained by the, Open Policy Agent (OPA) offers useful resources for cloud native infrastructure administrators. Their example Terraform workflow is available here.

OPA also hosts The Rego Playground for testing custom Terrascan rules.
