In Terraform, the depends_on meta-argument is used to create an explicit dependency between resources. It is used to specify that a particular resource depends on another resource and that the dependent resource should be created or updated before the resource that depends on it.

This allows Terraform to properly order the creation, modification, and destruction of resources, ensuring that dependent resources are created or modified only after the resources they depend on have been created or modified.

For example -

Let's say you have a Terraform configuration that creates an Amazon S3 bucket and an Amazon EC2 Instance.

The Amazon EC2 Instance depends on the Amazon S3 bucket, so it needs to be created the bucket before creating the EC2 instance. To specify this dependency, you would use the "depends_on" argument in the object resource block of EC2 Instance

In this tutorial we will take a look on -

2. How to use terraform depends_on metatag?
3. Demo example showing casing dependency between AWS EC2 and S3 Bucket.
