I am trying to use the default_tag
available for the AWS Terraform provider.
Documentation:
From the doc, it says:
This functionality is supported in all resources that implement tags, with the exception of the aws_autoscaling_group resource.
So, for all resources I have it works very well, except for aws_instance.root_block_device
.
For example, I have:
provider "aws" {
[...]
default_tags {
tags = {
Env = prod
}
}
}
resource "aws_instance" "instance" {
ami = xxx
instance_type = xxx
root_block_device {
volume_size = xxx
volume_type = xxx
}
}
The default tag Env = prod
is correctly added to the instance itself, but not for the root_block_device
block.
So I'm wondering if default_tag
is supported for this? It's true that the documentation says supported in all resources but root_block_device
is only an argument of this resource, so maybe this is the problem?
I'm just looking for a kind of confirmation because the documentation is not very clear on this point.
This is not supported yet. There are two issues are still open
but you can use this workaround solution:
data "aws_default_tags" "example" {}
aws_instance {
volume_tags = merge(data.aws_default_tags.example.default_tags, var.extra_tags)
}
