How do I set up a remote backend in Terraform?

To set up a remote backend in Terraform, you need to define the backend configuration in your Terraform configuration file. For example, you can use AWS S3 as a remote backend.

What do I need to include in the configuration?

You need to specify the backend type, such as 's3', and provide the bucket name, key, and region. Here's a sample configuration:

terraform {
  backend "s3" {
    bucket = "my-terraform-state"
    key    = "terraform.tfstate"
    region = "us-west-2"
  }
}

Do I need to configure anything else for state locking?

Yes, for state locking, you should enable DynamoDB for state locking by adding a 'dynamodb_table' parameter in your backend configuration.

Can you show me an example of that?

Sure! Here's how you can modify the configuration to include DynamoDB for state locking:

terraform {
  backend "s3" {
    bucket         = "my-terraform-state"
    key            = "terraform.tfstate"
    region         = "us-west-2"
    dynamodb_table = "my-lock-table"
  }
}
