How can I get all AWS Lambdas by Tag in Terraform-CodePudding

I have Lambdas with Tag of Name=production.

I would like to get them using Terraform, looking at aws_lambda_function, I can only get single lambda by function_name

data "aws_lambda_function" "existing" {
   function_name = var.function_name
}

You can use the aws_resourcegroupstaggingapi_resources to retrieve information for several AWS resources that don't have more specific data sources.

For your use case, considering Name=production, you can use:

data "aws_resourcegroupstaggingapi_resources" "existing" {
  resource_type_filters = ["lambda:function"]
  tag_filter {
    key    = "Name"
    values = ["production"]
  }
}

output "arns" {
  value = data.aws_resourcegroupstaggingapi_resources.existing.resource_tag_mapping_list.*.resource_arn
}

There is no data source to get multiple lambda functions. You have to create your own custom data source for detailed information about multiple lambda functions.
