Pure Cloud Block Store is a purpose-built block storage system that currently sits in AWS and Azure. It provides many benefits and serves many use cases.
Previously deployments of Cloud Block Store were done through a CloudFormations template that allowed provisioning. Some organizations wanted better ways to streamline deployment, so we introduced the Terraform Provider. With the Terraform Provider, you can provision a Pure Cloud Block Store instance on AWS in about 14 minutes.
Let’s dive in and take a look at how to utilize the new provider.
- Hashicorp Terraform: Used to automate the provisioning using a Terraform .TF file.
- Amazon Web Services Account: The infrastructure to run the EC2 virtual machines.
- AWS CLI: Used to create AWS credential file for authentication.
To set up the AWS credential file, open your operating system command-line interface and type the following command:
Enter in your AWS Access Key, AWS Secret Access Key, and Default AWS region. Once entered it will be saved in
Note: Download Cloud Block Store Deployment and Configuration Guide for AWS.
Before you can provision Pure Cloud Block Store, you need to configure a set of AWS prerequisities first by creating:
You’ll use these prerequisites in the terraform deployment.
Pure Cloud Block Store Terraform Setup
Note: Access sample terraform files.
The samples have been variablized for ease of deployment. You should only need to edit the
terraform.tfvars file with your parameters.
The documentation has an explanation for the cbs_array_aws resource parameters for a successful deployment.
Pure Cloud Block Store Terraform Deployments
Run Terraform initialize to set up provider
Run Terraform Plan to validate Terraform module and files.
If successful, it’s now time to deploy!
Once the deployment is complete you can run
terraform show to see the output and identify the controller IP addresses.
Alternatively, you can log to AWS and look up your CloudFormation Stack for the deployment outputs.
Cloud Block Store Decommission
Currently, destroying the Terraform resource will not deactivate the Pure Cloud Block Store instance. You’ll have to deactivate the instance manually once the resource has been destroyed. See the deployment guide for information on how to remove Pure Cloud Block Store instances.
For version 5.3.0.aws0, 5.3.0.aws1, and 5.3.0.aws2, Pure Cloud Block Store can only be removed (terminated) by Pure Support to ensure all the resources in the stack are cleanly removed. If you are on 5.3.3.aws0+ you can perform this without Pure Support involvement
Are you using Cloud Block Store or looking to test it out? This Terraform Provider can easily streamline deployment and testing in your environments! Future posts will expand on use cases on how to use Pure Cloud Block Store with AWS, Azure, VMware Cloud on AWS, and who knows what else!
