oci-redis

Redis is an open source, in-memory data structure store that is used as a database, cache, and message broker. It supports data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, HyperLogLogs, geospatial indexes with radius queries, and streams.

This reference architecture shows a typical six-node deployment of a Redis cluster on Oracle Cloud Infrastructure Compute instances.

For details of the architecture, see Deploy a highly available, distributed cache using Redis

Prerequisites

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

• Quota to create the following resources: 1 VCN, 1 subnets, 1 Internet Gateway, 1 NAT Gateway, 1 route rules, and 6 compute instance.

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-redis.git
cd oci-redis
ls

Set Up and Configure Terraform

1. Complete the prerequisites described here.

2. Rename provider.tf.cli to provider.tf

3. Create a terraform.tfvars file, and specify the following variables:

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

# Region
region = "<oci_region>"

# Compartment
compartment_ocid = "<compartment_ocid>"

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

Create the Resources

Run the following commands:

terraform init
terraform plan
terraform apply

Destroy the Deployment

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

terraform destroy
