Sentinel has a pluggable architecture which allows the core language to be extended for each product it is embedded into. » Writing policies in Terraform Enterprise Detailed syntax documentation and examples are available at. Policy code is where the Sentinel policy is entered. This is useful for policies that enforce regulatory requirements like "All database volumes must be encrypted." Hard mandatory mode does not allow any override, and policies must pass prior to an apply.This is useful for policies like "Users cannot provision outside of business hours", which require a failsafe. Soft mandatory mode requires an operator with appropriate permissions to override any policy failures prior to an apply.This is useful for teaching users good habits without preventing actions. Advisory mode logs warnings, but does not prevent runs from being applied.This is a detail required for entering policies in the UI or API.Įnforcement mode determines what happens in policy failure scenarios. Policy Name is a simple string used to identify Sentinel policies in Sentinel’s output. The screenshot below shows entering an organization policy in the web UI:Īll policies in Terraform Enterprise have a few configurable attributes: Policy code is entered into Terraform Enterprise using the API or the web UI, and will soon support VCS integration. Policies will also be configurable directly on workspaces in the future, which is a more suitable place to configure environment-specific policies such as “Development environments cannot have more than two app instances”. This is useful for defining organization-wide policies, such as “Disallow wide-open AWS Security Group Ingress”. Sentinel policies are configured on an organization and are applied to all runs on all workspaces within that organization. Terraform’s plan, configuration, and state data is made available to Sentinel through the tfplan plugin, enabling policy enforcements based on proposed changes to the infrastructure. Sentinel adds a new step to this process between the plan and apply, where any configured policies will be enforced. Terraform Enterprise provides a safe workflow for modifying infrastructure by first planning the changes to be made and then applying them if confirmed. » Terraform Enterprise and policy as code management ![]() More details are in the Announcing Sentinel, HashiCorp’s Policy as Code Framework blog. Sentinel is embedded into the Enterprise version of each of HashiCorp's products including Terraform, Vault, Consul, and Nomad. ![]() A policy describes under what circumstances certain behaviors are allowed. Sentinel is HashiCorp's language and framework for embedding policy as code into existing software, enabling fine-grained, logic-based policy decisions. Providing policy as code allows these types of constraints to be codified and automated with Sentinel in Terraform Enterprise. Manual enforcement of these constraints becomes increasingly difficult as the demand for infrastructure provisioning grows. Not allowing resources to be provisioned outside of business hours.Restricting AWS security group ingress and egress settings by CIDR block.Not allowing “development” resources to be provisioned in “us-east-1”.Not allowing resources to be provisioned without tags.Sentinel policy as code places guardrails to protect users from creating infrastructure changes that fall outside of business and/or regulatory policies. This comes with risks, as every action can have larger effects. ![]() Infrastructure as code with HashiCorp Terraform enables operators to automate provisioning at scale.
