Terraform data block example. A data source, also known as data resources, allows Terraform to fetch and use information from resources defined outside Terraform or managed by a different Terraform configuration. We’ll discuss what data blocks are, how to use them, and some of the benefits of using data blocks. We’re then outputting several attributes of the bucket using the output block. tf files instead of hardcoding it. Example: A data block requests that Terraform read from a given data source ("aws_ami") and export the result under the given local name ("example"). Here’s what that dynamic block's syntax would look like: dynamic "label" { for_each = var. To demonstrate how these work, let's use an example of a dynamic block that creates multiple configurations based on a list of input values. The name is used to refer to this resource from elsewhere in the same Terraform module, but has no significance outside of the scope of a module. We’ll also provide some examples of how In this example, we’re using the aws_s3_bucket data source to retrieve information about an existing S3 bucket named example-bucket. Example: Below code fetches the AWS AMI ID and uses it to launch AWS instance. A data block requests that Terraform read from a given data source ("aws_ami") and export the result under the given local name ("example"). Data sources are used to fetch the data from the provider end, so that it can be used as configuration in . In this article, we’ll take a closer look at data blocks in Terraform. content { A data block requests that Terraform read from a given data source ("aws_ami") and export the result under the given local name ("example"). A data resource also supports count and for_each arguments. iterable_variable . iterator = iterator_name # Optional, defaults to label. A data resource must be defined using a data block like the example below: Basic Syntax. content {. The name is used to refer to this resource from elsewhere in the same Terraform module. klmsdijxteielaxupsbagygpnrntgzlzproyckrfqkbourfnkutr
