DynamoDB table for state locking and consistency checking on terraform

2 min read

When using a remote terraform state with S3, it is recomended to use a dynamoDB table for:

• State locking: Ensures the terrafrom state it is not being modified by two threads at the same time
• Consistency checking: Makes sure that that terraform it's being used it is the one that it is expected to be used

For example:

terraform {
  backend "s3" {
    bucket         = "infra-tfstate"
    key            = "jenkins/terraform.tfstate"
    region         = "eu-west-1"
    dynamodb_table = "terraform_locks"
  }
}
