For example, there are many JSON files in the path
./test1.json
./test2.json
./test3.json
...
I want to create multiple tasks with different ids
resource "aws_dms_replication_task" "test1" {
replication_task_id = "test-dms-replication-task-tf-test1"
table_mappings = file("${path.module}/test1.json")
source_endpoint_arn = aws_dms_endpoint.test-dms-source-endpoint-tf.endpoint_arn
target_endpoint_arn = aws_dms_endpoint.test-dms-target-endpoint-tf.endpoint_arn
}
resource "aws_dms_replication_task" "test2" {
replication_task_id = "test-dms-replication-task-tf-test2"
table_mappings = file("${path.module}/test2.json")
source_endpoint_arn = aws_dms_endpoint.test-dms-source-endpoint-tf.endpoint_arn
target_endpoint_arn = aws_dms_endpoint.test-dms-target-endpoint-tf.endpoint_arn
}
...
Put them into one resource, is there a way to use for_each?
CodePudding user response:
You can do this with for_each. For example:
variable "rule_files" {
default = ["test1", "test2", "test3"]
}
resource "aws_dms_replication_task" "test" {
for_each = var.rule_files
replication_task_id = "test-dms-replication-task-tf-${each.key}"
table_mappings = file("${path.module}/${each.key}.json")
source_endpoint_arn = aws_dms_endpoint.test-dms-source-endpoint-tf.endpoint_arn
target_endpoint_arn = aws_dms_endpoint.test-dms-target-endpoint-tf.endpoint_arn
}
Once this is done, you can refer to individual instances of aws_dms_replication_task
using key value. For example:
aws_dms_replication_task.test["task1"].replication_task_arn
