The valid values are PROVISIONED or PAY_PER_REQUEST, Controls if DynamoDB table and associated resources are created. If you have multiple environments, you can use the same DynamoDB table to maintain the state lock in the same AWS account, you don’t need to have individual DynamoDB tables for different environments. DynamoDB table items cannot be imported. Prevention of accidental destruction of the S3 bucket while running terraform operations; DynamoDB table # # create a dynamodb table for locking the state file. (Not all of the attributes are shown.) In the Access keys section, choose Create access key. Each item in GameScores is identified by a partition key (UserId) and a sort key (GameTitle). This attribute should only be specified if the key is different from the default DynamoDB CMK, alias/aws/dynamodb. It is different from CloudFormation nested stacks because changes are applied to the whole set, not sub-templates. Only the primary key attributes are required; you can optionally provide other attribute name-value pairs for the item. (Not all of the attributes are shown.) billing_mode is set to PAY_PER_REQUEST, and we are trying to apply a new range_key = "typeAndId" * provider.aws: version = "~> 1.58" Terraform has been successfully initialized!

Managing state with terraform is quite crucial, when we are working with multiple developers in a project, with remote operation and sensitive data, let’s see how to use AWS Backend with S3 and DynamoDB table for remote state and locking for a Terraform project. Only available when var.stream_enabled is true, A timestamp, in ISO 8601 format of the Table Stream. Here is the DynamoDB Table with the “LockID”, initially the table will be empty and no entries can be seen. So I don’t need to add this code snippet to the source terraform code. The ARN of the CMK that should be used for the AWS KMS encryption. Region names for creating replicas for a global DynamoDB table. Otherwise it will not allow you to proceed with the changes. region: (String) the region to deploy to. When applying these Terraform configuration it creates a DynamoDB table with the name “tf-remote-state-lock” along with the “LockID” to maintain a state lock while there is an ongoing configuration “apply” to the environment. Partition key of an item is also termed as hash key or hash attribute. Hey, the whole purpose of DynamoDB locking is braking the state from multiple updates to the environment. unique_id - The unique ID assigned by AWS. If it is blocking the simultaneous updates, it’s the expected behavior. The attribute to use as the range (sort) key.
