terraform_creating_elastic_scaleset_with_postgres is template that building an Elastic High Availability virtual network on azure with terraform code. On that infrastructure we are going to deploy a Node.js Weight Tracker App. input for variables for via .tfvars:

• instance_num =
• VnetName = ""
• ScaleSetName = ""
• admin_user_name = ""
• admin_password = ""
• pg_user = ""
• pg_pass = ""

blob_creation template create container inside blob storage and stores terraform.tfstate file in there (inside RG).

Input variables for port creation via .tfvars:

• resource_group_name = ""
• location = ""
• storage_account_name = ""
• storage_container_name = ""

The second template blob_insert_into_container inserts file terraform.state inside blob storage container. In order to do that, inset in this folder terraform.state.

Commands to run templates:

• // init
• terraform init
• // plan
• terraform plan
• // apply
• terraform apply

please notice if .tfvars file is needed to add to command: -var-file="{filename}.tfvars"
