Explanation
This command will initialize the new backend and prompt you to migrate the existing state file to the new location3. The other commands are not relevant for this task.

Explanation
The required_providers block is used to specify the provider versions that the configuration can work with.
The version argument accepts a version constraint string, which must be enclosed in double quotes. The version constraint string can use operators such as >=, ~>, =, etc. to specify the minimum, maximum, or exact version of the provider. For example, version = ">= 3.1" means that the configuration can work with any provider version that is 3.1 or higher. References = [Provider Requirements] and [Version Constraints]

Child modulesdo not automatically inheritvariables from the parent module.
* To pass values from theparent moduleto thechild module, you mustexplicitly define input variablesin the child module and pass them in the parent module.
* Example:
hcl
CopyEdit
module "example" {
source = "./child_module"
var1 = "value"
}

Passing Variables to Modules

You do not need to use different Terraform commands depending on the cloud provider you use. Terraform commands are consistent across different providers, as they operate on the Terraform configuration files and state files, not on the provider APIs directly.

Explanation
To output returned values from a child module in the Terraform CLI output, you need to declare the output in both the child module and the root module. The child module output will return the value to the root module, and the root module output will display the value in the CLI. References = [Terraform Outputs]
