Thank you for using Terraform and for opening up this question! DynamoDB auto scaling. }. provisioner "local-exec" { "provisionedThroughput": { "errorCode": "ValidationException", The first element in this policy is the Version, which defines the JSON version that we’re using. Pin module version to ~> v3.0. Terraform AWS Provider version 2.31.0 and later automatically handles this increased timeout, however prior versions require setting the customizable deletion timeout to 45 minutes (delete = "45m"). Sign up for a free GitHub account to open an issue and contact its maintainers and the community. In the terminal, navigate to proj directory and run the command terraform init. This module requires AWS Provider >= 1.17.0 All DynamoDB quotas remain in effect, as described in Service, Account, and Table Quotas in Amazon DynamoDB. I tried to create them (using the table/my-table/index/my-table-index resource-id as specified in the AWS docs) but I get an error from terraform, aws_appautoscaling_target.dynamodb_index_read_target: Error creating application autoscaling target: ValidationException: Unsupported service namespace, resource type or scalable dimension, Was just about to share and noticed my mistake! Step 2: Now, we will zip index.js into index.zip using any zipping software or using CLI and will keep this zip file into the same directory only. https://docs.aws.amazon.com/lambda/index.html, https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/lambda_function, Documentation of deploying AWS Lambda using terraform, https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/dynamodb_table, Documentation of deploying DynamoDB using terraform, $ aws s3api create-bucket --bucket=mybucket98745 --region=us-east-1, $ aws s3 cp index.zip s3://mybucket98745/index.zip, resource "aws_dynamodb_table" "ddbtable" {, resource "aws_iam_role_policy" "lambda_policy" {, resource "aws_lambda_function" "myLambda" {, Learn to Build a Web Application with Swift Language + Vapour, Kubernetes — Learn Sidecar Container Pattern, Your Knowledge Portfolio as a Software Developer, Why Instance Variable Of Super Class Is Not Overridden In Sub Class. "errorMessage": "2 validation errors detected: Value '-1' at 'provisionedThroughput.writeCapacityUnits' failed to satisfy constraint: Member must have value greater than or equal to 1; Value '-1' at 'provisionedThroughput.readCapacityUnits' failed to satisfy constraint: Member must have value greater than or equal to 1", terraform init. In DynamoDB's UI, they have the option "Apply same settings to global secondary indexes". DynamoDB is a fully managed, fast, highly scalable, and flexible cloud database service for applications that need consistent, single-digit millisecond latency at any scale. Only required for hash_key and range_key attributes. terraform apply. :) After looking for some examples and some documentation, I saw that there is no simple and working example, especially for DynamoDB autoscaling … It will deploy all the resources into AWS cloud, which we can confirm by opening the AWS console in the browser. Requirements. Tagged with terraform, aws, dynamodb, devops. Pin module version to ~> v2.0. And that’s it! If you feel this issue should be reopened, we encourage creating a new issue linking back to this one for added context. Hi, I recently added aws_appautoscaling_target and aws_appautoscaling_policy resources to my terraform to turn on autoscaling for a DynamoDB table. And that’s it! Hi everyone! For Amazon ECS, Spot Fleet, and Amazon RDS, both StepScaling and TargetTrackingScaling are supported. Amazon DynamoDB has two read/write capacity modes for processing reads and writes on your tables: The read/write capacity mode controls how you are charged for read and write throughput and how you manage capacity. "readCapacityUnits": -1 Step 3: Now we’ll create an IAM access policy with JSON to grant the required permissions to the DynamoDB table. However, when TF creates that scaling policy, it does specify zero's. Instead, we’ll trigger the Lambda function using the test events that is already present in the Lambda console. provisioner "local-exec" { Here, we won’t use any other AWS services to trigger the Lambda function. As there have been multiple workarounds and solutions posted, this issue will now be closed. The next element is Statement, which is the main section of the policy and includes multiple elements. DynamoDB auto scaling doesn't prevent you from manually modifying provisioned throughput settings. This article provides a brief example how to deal with auto-scaling in AWS by using terraform. "writeCapacityUnits": -1, (ID: terraform-asg-example) aws_autoscaling_group.example: Refreshing state... (ID: tf-asg-20171010122315457300000002) The Terraform execution plan has been generated and is shown below. Each attribute has two properties: name - (Required) The name of the attribute, type - (Required) Attribute type, which must be a scalar type: S, N, or B for (S)tring, (N)umber or (B)inary data All DynamoDB quotas remain in effect, as described in Service, Account, and Table Quotas in Amazon DynamoDB. Can we add this to the terraform resource? In the proj directory, we’ll create two json files named assume_role_policy.json and policy.json. You should have a basic knowledge of Node.js. Please make sure to provide us with the information requested in the template as well as any additional appropriate information so we can best determine how to assist with the given issue. Published 7 days ago. The assume_role_policy.json contains the following —. How can we perform dynamodb index autoscaling using terraform..? AWS and HashiCorp are working together to reduce the amount of time required for resource deletion and updates can be tracked in this GitHub issue . Terraform module to provision a DynamoDB table with autoscaling. In console index values will show different because these R/W values will changes while Auto-scaling time. Only required for hash_key and range_key attributes. otherwise, Terraform will reset the capacity on every run. On-demand — Amazon DynamoDB on-demand is a flexible billing option capable of serving thousands of requests per second without capacity planning. You have predictable application traffic. The above workarounds should not be necessary. Each of the notifications map to a Notification Configuration inside Amazon Web Services, and are applied to each AutoScaling Group you supply. Now, we’ll create an S3 bucket from the terminal using the command -. Don't get me wrong, it works perfectly fine. At last, we’ll create our lambda function whose name will be func, which will load the code from index.zip stored in an S3 bucket named mybucket98745. Latest Version Version 3.19.0. DynamoDB auto scaling can increase read capacity or write capacity as often as necessary, in accordance with your auto scaling policy. This module requires AWS Provider >= 1.17.0 ... an example Terraform Configuration is below: ... no streams, and no Autoscaling. But then when adding more GSIs/modifying the current one we have to do that strange dance of: It feels very awkward, almost like GSI should be a separate resource, maybe? They do not exist for resources created manually in the Console. I have also spoken to AWS regarding the error message (Auto Scaling settings already exist for global secondary indexes. I had not changed the scalable_dimension when I copied it from my table target. We’ll also attach the role to it that we have already created. ... by creating alarms through the DynamoDB Console. This helps our maintainers find and focus on the active issues. The autoscaling is setup for both table and the GSI, but If I go to the Capacity tab of the table in AWS console, I see the following warning: Not that I will use the console to update the settings, but I don't understand why this warning shows up when creating the autoscaling stuff, but not when you create the autoscaling stuff through the console.
