oci-cockroachdb

This is a Terraform code that deploys CockroachDB on Oracle Cloud Infrastructure (OCI). It is developed jointly by Oracle and Cockroach Labs.

This reference architecture shows a typical three-node deployment of CockroachDB on Oracle Cloud Infrastructure Compute instances. A public load balancer is used to distribute the workloads across these three nodes.

For details of the architecture, see Deploy a highly available CockroachDB cluster

Prerequisites

• Permission to manage the following types of resources in your Oracle Cloud Infrastructure tenancy: vcns, internet-gateways, route-tables, security-lists, subnets, and instances.

• Quota to create the following resources: 1 VCN, 1 subnet, 1 Internet Gateway, 1 route rules, 1 Load Balancer, and 3 CockroachDB compute instances.

If you don't have the required permissions and quota, contact your tenancy administrator. See Policy Reference, Service Limits, Compartment Quotas.

Deploy Using Oracle Resource Manager

1. Click

   If you aren't already signed in, when prompted, enter the tenancy and user credentials.

2. Review and accept the terms and conditions.

3. Select the region where you want to deploy the stack.

4. Follow the on-screen prompts and instructions to create the stack.

5. After creating the stack, click Terraform Actions, and select Plan.

6. Wait for the job to be completed, and review the plan.

   To make any changes, return to the Stack Details page, click Edit Stack, and make the required changes. Then, run the Plan action again.

7. If no further changes are necessary, return to the Stack Details page, click Terraform Actions, and select Apply.

Deploy Using the Terraform CLI

Clone the Module

Now, you'll want a local copy of this repo. You can make that with the commands:

git clone https://github.com/oracle-quickstart/oci-cockroachdb
cd oci-cockroachdb
ls

Prerequisites

First off, you'll need to do some pre-deploy setup. That's all detailed here.

Secondly, create a terraform.tfvars file and populate with the following information:

# Authentication
tenancy_ocid         = "<tenancy_ocid>"
user_ocid            = "<user_ocid>"
fingerprint          = "<finger_print>"
private_key_path     = "<pem_private_key_path>"

# Region
region = "<oci_region>"

# Availablity Domain 
availablity_domain_name = "<availablity_domain_name>" # for example GrCH:US-ASHBURN-AD-1

# Compartment
compartment_ocid        = "<compartment_ocid>"

Create the Resources

Run the following commands:

terraform init
terraform plan
terraform apply

Verify the Deployment

Copy loadbalancer_public_url output and verify the access with your web browser:

Destroy the Deployment

When you no longer need the deployment, you can run this command to destroy the resources:

terraform destroy
