Terraform data block example. 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. We’re then outputting several attributes of the bucket using the output block. 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. A data resource must be defined using a data block like the example below: Basic Syntax. In this article, we’ll take a closer look at data blocks in Terraform. tf files instead of hardcoding it. We’ll discuss what data blocks are, how to use them, and some of the benefits of using data blocks. 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. content {. Example: Below code fetches the AWS AMI ID and uses it to launch AWS instance. Data sources are used to fetch the data from the provider end, so that it can be used as configuration in . The name is used to refer to this resource from elsewhere in the same Terraform module. Here’s what that dynamic block's syntax would look like: dynamic "label" { for_each = var. 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. iterable_variable . 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"). 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. iterator = iterator_name # Optional, defaults to label. A data block requests that Terraform read from a given data source ("aws_ami") and export the result under the given local name ("example"). febxa fdshj dwmzuct olyp ene rta aoidyzof xdxs tzxd rdffwmv
