Terraform contd

• Order of Creation: Order of creation can be acheived in two ways
  • explicit dependency using depends_on Refer Here
    • Refer Here for the usage
  • implicit dependency: Terraform figures out by looking at your configuration/template
    • When the output (attribute) of one resource is used as input (argument) to other
    • Refer Here for the changes
• To use one resource in other resource argument <resource_type>.<name>

depends_on = [ azurerm_resource_group.myresg ]

Best Practice to write terraform template (Based on what we have covered so far)

• Terraform reads all the .tf files in the folder and then combines as one file and executes the terraform => While writing terraform templates there is no need write everything in one file
  • From now one lets have one tf for provdier and then one tf file for logical group of resources.
  • All the variables will be in one file inputs.tf and all the outputs will be in the file outputs.tf
    
• Use terraform fmt to align the terraform template into common canonical format Refer Here for the changes done
