Announcing Oracle Cloud Infrastructure Resource Manager

Sneha Narang
Senior Product Manager

We are excited to announce a new service, Oracle Cloud Infrastructure Resource Manager, that makes it easy to manage your infrastructure resources on Oracle Cloud Infrastructure. Resource Manager enables you to use infrastructure as code (IaC) to automate provisioning for infrastructure resources such as compute, networking, storage, and load balancing.

Using IaC is a DevOps practice that makes it possible to provision infrastructure quickly, reliably, and at any scale. Changes are made in code, not in the target systems. That code can be maintained in a source control system, so it’s easy to collaborate, track changes, and document and reverse deployments when required.

HashiCorp Terraform

To describe infrastructure Resource Manager uses HashiCorp Terraform, an open source project that has become the dominant standard for describing cloud infrastructure. Oracle is making a strong commitment to Terraform and will enable all its cloud infrastructure services to be managed through Terraform. Earlier this year we released the Terraform Provider, and we have started to submit Terraform modules for Oracle Cloud Infrastructure to the Terraform Module Registry. Now we are taking the next step by providing a managed service.

Managed Service

In addition to the provider and modules, Oracle now provides Resource Manager, a fully managed service to operate Terraform. Resource Manager integrates with Oracle Cloud Infrastructure Identity and Access Management (IAM), so you can define granular permissions for Terraform operations. It further provides state locking, gives users the ability to share state, and lets teams collaborate effectively on their Terraform deployments. Most of all, it makes operating Terraform easier and more reliable.

With Resource Manager, you create a stack before you run Terraform actions. Stacks enable you to segregate your Terraform configuration, where a single stack represents a set of Oracle Cloud Infrastructure resources that you want to create together. Each stack individually maps to a Terraform state file that you can download.

To create a stack, you define a compartment and upload the Terraform configuration while creating this stack. This zip file contains all the .tf files that define the resources that you want to create. You can optionally include a variables.tf file or define your variables in a (key,value) format on the console.

After your stack is created, you can run different Terraform actions like planapply, and destroy on this stack. These Terraform actions are called jobs. You can also update the stack by uploading a new zip file, download this configuration, and delete the stack when required.

Plan: Resource Manager parses your configuration and returns an execution plan that lists the Oracle Cloud Infrastructure resources describing the end state.

Apply: Resource Manager creates your stack based on the results of the plan job. After this action is completed, you can see the resources that have been created successfully in the defined compartments.

Destroy: Terraform attempts to delete all the resources in the stack.

You can define permissions on your stacks and jobs through IAM policies. You can define granular permissions and let only certain users or groups perform actions like plan, apply, or destroy.

Availability

Resource Manager will become generally available in early 2019. We are currently providing access to selected customers through our Cloud Native Limited Availability Program. The currently available early version offers access to the Compute, Networking, Block Storage, Object Storage, IAM, and Load Balancing services.
