Create a Redis Cloud subscription with Terraform

In your Terraform configuration file, you can add resources and data sources to plan and create subscriptions and databases. See the Redis Cloud Terraform Registry documentation for more info about the resources and data sources you can use as part of the Redis Cloud provider.

The steps in this section show you how to plan and create a Redis Cloud Pro subscription with one database.

1. Use the rediscloud_payment_method data source to get the payment method ID.

   # Get credit card details
   data "rediscloud_payment_method" "card" {
       card_type = "<Card type>"
       last_four_numbers = "<Last four numbers on the card>"
   }
   

   Example:

   data "rediscloud_payment_method" "card" {
      card_type = "Visa"
      last_four_numbers = "5625"
   }
   

2. Define a rediscloud_subscription resource to create the subscription.

   # Create a subscription
   resource "rediscloud_subscription" "subscription-resource" {
           name = "subscription-name"
           payment_method_id = data.rediscloud_payment_method.card.id # If you want to pay with a marketplace account, replace this line with payment_method = 'marketplace'.
           memory_storage = "ram"
   
           # Specify the cloud provider information here
           cloud_provider {
                   provider = "<Cloud provider>"
                   region {
                           region = "<region>"
                           networking_deployment_cidr = "<CIDR>"
                   }
           }
   
           #Define the average database specification for databases in the subscription
           creation_plan {
                   memory_limit_in_gb = 2
                   quantity = 1
                   replication = true
                   throughput_measurement_by = "operations-per-second"
                   throughput_measurement_value = 20000
           }
   }
   

   Example:

   resource "rediscloud_subscription" "subscription-resource" {
        name = "redis-docs-sub"
        payment_method_id = data.rediscloud_payment_method.card.id # If you want to pay with a marketplace account, replace this line with payment_method = 'marketplace'.
        memory_storage = "ram"
   
        cloud_provider {
                provider = "GCP"
                region {
                        region = "us-west1"
                        networking_deployment_cidr = "192.168.0.0/24"
                }
        }
   
        creation_plan {
                memory_limit_in_gb = 2
                quantity = 1
                replication = true
                throughput_measurement_by = "operations-per-second"
                throughput_measurement_value = 20000
                modules = ["RedisJSON"]
        }
   }
   

3. Define a rediscloud_subscription_database resource to create a database.

   # Create a Database
   resource "rediscloud_subscription_database" "database-resource" {
       subscription_id = rediscloud_subscription.subscription-resource.id
       name = "database-name"
       memory_limit_in_gb = 2
       data_persistence = "aof-every-write"
       throughput_measurement_by = "operations-per-second"
       throughput_measurement_value = 20000
       replication = true
   
       alert {
       name = "dataset-size"
       value = 40
       }
       depends_on = [rediscloud_subscription.subscription-resource]
   
   }
   

   Example:

   resource "rediscloud_subscription_database" "database-resource" {
       subscription_id = rediscloud_subscription.subscription-resource.id
       name = "redis-docs-db"
       memory_limit_in_gb = 2
       data_persistence = "aof-every-write"
       throughput_measurement_by = "operations-per-second"
       throughput_measurement_value = 20000
       replication = true
   
       modules = [
       {
            name = "RedisJSON"
       }
       ]
   
       alert {
       name = "dataset-size"
       value = 40
       }
      depends_on = [rediscloud_subscription.subscription-resource]
   
   }
   

4. Run terraform plan to check for any syntax errors.

   $ terraform plan
   data.rediscloud_payment_method.card: Reading...
   data.rediscloud_payment_method.card: Read complete after 1s [id=8859]
   
   Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the following
   symbols:
   + create
   
   Terraform will perform the following actions:
   
       # rediscloud_subscription.subscription-resource will be created
       + resource "rediscloud_subscription" "subscription-resource" {
           [...]
       }
   
       # rediscloud_subscription_database.database-resource will be created
       + resource "rediscloud_subscription_database" "database-resource" {
           [...]
       }
   
   Plan: 2 to add, 0 to change, 0 to destroy.
   

5. Run terraform apply to apply the changes and enter yes to confirm when prompted.

   This will take some time. You will see messages in your terminal while the subscription and database are being created:

   rediscloud_subscription.subscription-resource: Creating...
   rediscloud_subscription.subscription-resource: Still creating... [10s elapsed]
   rediscloud_subscription.subscription-resource: Still creating... [20s elapsed]
   rediscloud_subscription.subscription-resource: Still creating... [30s elapsed]
   

   When provisioning is complete, you will see a message in your terminal:

   Apply complete! Resources: 2 added, 0 changed, 0 destroyed.
   

   View the Redis Cloud console to verify your subscription and database creation.

6. If you want to remove these sample resources, run terraform destroy.
