Today, the Sentinel team is pleased to announce the release of the Sentinel Playground. We have built the Playground so that new and existing customers have access to a zero-install development environment. Now, practitioners can learn and experiment with policy as code in minutes without having to install and maintain runtime environments on their own machines.

Engineers are becoming the new cloud financial controllers as finance teams begin to lose some of their direct control over new fast-paced, on-demand infrastructure consumption models driven by cloud. So the question becomes: What are the people, processes, and technologies I can use to navigate this sea change?

HashiCorp Terraform provides cloud infrastructure automation with infrastructure and policies as code. Policy as code is becoming the popular approach to embedding guardrails into the provisioning workflow while not slowing down end-users who are provisioning infrastructure. Terraform uses Sentinel policy as code to embed these policies. Today we are pleased to announce the preview release of the Terraform Foundational Policies Library for Terraform Cloud.

Announcing Terraform Foundational Policy Library Preview

Last month we announced a technical preview of the next generation of Sentinel imports in Terraform Cloud. We are now happy to announce the API is stable and generally available for use in production for Terraform Sentinel policies.

Terraform Sentinel v2 Imports Are Now GA

We've released a tech preview of Sentinel's completely re-designed import API, which better reflects Terraform 0.12's updated data model.

Terraform Sentinel v2 Imports Now in Technology Preview

Last November we announced the release of the tfrun import for Sentinel in Terraform Enterprise and Cloud. The release of the new tfrun import provided customers with an improved policy authoring workflow and the flexibility to author policies that could be applied to an entire organization and reduce the need for policy duplication. Since then we have had a steady flow of feedback from customers covering different use cases that prompted us to extend the list of attributes exposed by the tfrun import.

Expanding the tfrun import for Sentinel in Terraform Enterprise and Cloud

This is a guest blog case study by AGL Energy, Australia’s largest private developer of renewable energy assets. Hear how they use Terraform Enterprise and Sentinel policy as code.

How AGL Uses HashiCorp Terraform Enterprise and Sentinel to Enable Cloud Native Capabilities

HashiCorp Terraform users who are implementing policy as code with HashiCorp Sentinel have been looking for improved ways to write policies that are broad enough to apply to their entire organizations while also being able to accomodate the detail or needs specific to individual groups within the organization. To help support this need, Sentinel policies now support enforcement decisions based on data from context in which policies are run.

The Sentinel Getting Started track on the Learn platform will teach new users policy vocabulary, how to build policies, creating policy sets, mocking and testing policies with the Sentinel Simulator, and using the Terraform Sentinel Provider.

Terraform Learning Resources: Getting Started with Sentinel in Terraform Cloud

We are excited to announce the publication of a new Writing and Testing Sentinel Policies for Terraform Enterprise Guide to our Resource Library. This comprehensive guide teaches you how to write and test governance policies that restrict the infrastructure provisioned by Terraform Enterprise.

Writing and Testing Sentinel Policies for Terraform Enterprise

In addition to providing for more rapid deployments, Terraform has features for securing those deployments and lowering risk.This blog will cover the features you can use to improve the security posture of your infrastructure: Sentinel policy as code, Terraform module registry, and HashiCorp Vault integration.

Using Terraform to Improve Infrastructure Security Posture

Using HashiCorp Terraform Enterprise and the Kubernetes provider we can apply fine-grained policy enforcement using Sentinel to Kubernetes resources, before the changes to the resources are applied on the cluster. This blog post explores using Sentinel in Terraform Enterprise to manage Kubernetes clusters and enforce Kubernetes service types and namespace naming conventions.

Applying Policy as Code to Kubernetes Resources

In the same way that we can embed Sentinel into a pipeline to enforce policy for Terraform plans, or Vault secrets, we can also enforce policy in a continuous delivery pipeline.

In this post, we are going to examine how Sentinel Policy and the Sentinel Simulator can be used to ensure your CD system only deploys your application within a specified time window.

Using Sentinel Policy to enforce continuous deployment windows

Infrastructure as code with HashiCorp Terraform enables operators to automate provisioning at scale. This comes with risks, as every action can have larger effects. Sentinel policy as code places guardrails to protect users from creating infrastructure changes that fall outside of business, security, and compliance policies. This blog will take a look at writing and enforcing a policy using Terraform Enterprise to restrict provisioning resources in certain availability zones to ensure data sovereignty.

TFE and Sentinel: Provisioning Policy for Data Sovereignty in the Cloud

HashiCorp advocates for "infrastructure as code" approaches to managing infrastructure. We have talked about it publicly and published about it in our  Tao of HashiCorp. At HashiConf 2017, we announced Sentinel, a framework for "policy as code". The same coding practices that are applied to infrastructure can be very effective in enforcing and managing policies. Codifying policy removes the need for ticketing queues, without sacrificing enforcement.

Why Policy as Code?

Infrastructure as code with HashiCorp Terraform enables operators to automate provisioning at scale. This comes with risks, as every action can have larger effects. Sentinel policy as code places guardrails to protect users from creating infrastructure changes that fall outside of business and/or regulatory policies.

Sentinel and Terraform Enterprise: Applying policy as code to infrastructure provisioning

Sentinel is an embedded policy as code framework in the HashiCorp Enterprise products to enable fine-grained, logic-based policy guardrails.

Announcing Sentinel, HashiCorp’s Policy as Code Framework

Today at HashiConf 2017 in Austin, Texas, we announced major updates and new features across our entire suite of open source and enterprise products, including HashiCorp Terraform, HashiCorp Vault, HashiCorp Consul, and HashiCorp Nomad. In addition to these product updates, we announced the release of Sentinel, our new policy as code framework that integrates across the Enterprise product suite, and the Terraform Module Registry, which provides example infrastructure templates to make provisioning across cloud environments easier, and so much more.
