How to load all json files for `aws_dynamodb_table_item`

[dongla...@gmail.com]

Hey,

Confused to apply `aws_dynamodb_table_item` to load all json files in some directory which path i can get from tfvars. 

I did the following code to try, and get failed. How to apply `dirname` to get file name list, and pass to a variable with type list?  or other idea?

variable "json_file_name_list" {

  type = "list"

 default= '${dirname(var.path)}'

}

resource "aws_dynamodb_table_item" "init-items" {

 count = "${length(var.json_file_name_list)}"

 table_name = "${var.table_name}"

 hash_key = "key"

 item = <<EOF

${file("${var.path}${element(var.json_file_name_list, count.index)}.json")}

EOF

}

Regards,

Donglai

Hi,

Use shell script to get all file name in variable and dynamodb restore script as well as you need to use provisioner with terraform i.e. local and remote exe to perform Desired functionality that will work.

Thank you for your replying, and the following is my understand, is that your suggest:

Approach - 1:

in `build.sh`, apply `ls` and regarding script to get all filenames, then execute `TF_VAR_jsonfilelist=['file1.json','file2.json'...] terraform apply` instead of `terraform apply` directly.

Approach - 2: 

apply provisioner in initialized module, something like 

resource "null_resource" "get_file_list" {
   provisioner "local-exec" {
        command = "ls ${var.data_file_path} > file_json_list"
   }
}
output "json_file_list" {
value =<<EOF
${file("file_json_list")}
EOF
}

Then, applied variable `json_file_list ` in dynamo restore.
