What is Terraform null_resource and how to use it? - Part-21

To learn more on null_resource visit - jhooq.com/terraform-null-reso...
To use the null_resource in Terraform, you first need to declare the resource block and specify a unique name for it. Within the resource block, you can specify a provisioner block
Here's an example of how you can use the null_resource in Terraform:
resource "null_resource" "example" {
provisioner "local-exec" {
command = "echo Hello world"
}
}
The null_resource can be used to perform actions that don't create any infrastructure resources, such as running a local script or making an API call. In the provisioner block, you can specify the desired configuration options for the null_resource, such as the script that should be run or the API endpoint that should be called.

thank you for sharing knowledge

[@RahulWagh]

My pleasure

[@danishnoman2042]

Just to make a correction: in the null resource, it prints the ID of the null resource not of EC2 instance. Rest is good. Thanks

[@lnkrishnan]

Thanks for your videos. Very helpful. BTW, Can you do some advanced topics on infrastructure provisioning with terraform using modules? Say using one module for VPC creation, another for EC2 instance provisioning, and a third that provisions application LB. Simple requirement would be to setup VPC, and in it, provision the internet facing ALB in the public subnet that loadbalances over 3 EC2 instances in private subnets spread over 3 AZs. Is that something you can showcase? Would be much appreciated.

Hi Nice explanation... I have the below code, can you explain to me what it will do data "null_data_source" "tags_ec2" { count = length(keys(local.tags_ec2_raw)) inputs = { Key = element(keys(local.tags_ec2_raw), count.index) Value = element(values(local.tags_ec2_raw), count.index) } }
