Azure App VNet

  1. Create a Resource Group
  2. Create a VNet
  3. Create a Subnet in the VNet
  4. Create and associate a route table for the subnet
  5. Add a default route to IGW in the subnet route table
  6. Add a security group
  7. Create a VM
  8. Add inbound rule to allow 80 and 443 from 0.0.0.0/0
  9. Add inbound rule to allow ssh from the current ip
  10. Add outbound firewall rule to allow all traffic out
  11. Add a route to go the internet for the current ip (This is added in case you want to set a different default route via firewall instances etc)

Variables

  • prefix - Prefix used for all the resources, default kiran-app
  • location - AZure Location, default eastus
  • zones - Availability zones in the above location, default [1], (This is not running properly, so not used in the module)
  • vnet_cidr - VNet CIDR, defaults to 10.0.0.0/16
  • subnet_bits - Additional bits to use for each of the subnets. Final subnet would be the mask of VPC CIDR + the value provided for this variable, default 8
  • ssh_public_key_file - SSH Public Key File
  • instance_size - Instance size of the VM, default Standard_B1s
  • vm_count_per_zone - Number of VM instances per Zone, default 1
  • external_ips - List of IPs for which the SSH access is enabled (used in the ssh ingress firewall rule), by default add the current IP. These are the additional IPs

Outputs

  • vms - A list of VMs, each item is a map, with all the details of the map 
    [
  {
    "name" = "kiran-app-az0-vm0"
    "private_ip" = "10.0.0.4"
    "public_ip" = "<public_ip>"
    "security_group" = "kiran-app-sg"
    "ssh_cmd" = "ssh ubuntu@<public_ip>"
    "vpc" = "vnet-id"
    "vnet" = "vnet-id"
  },
]
  • vnet - VNet object details 
    {
  "cidr" = "10.0.0.0/16"
  "id" = "vnet-id"
  "name" = "kiran-app-vnet"
  "resource_group_name" = "kiran-app-rg"
  "subnet" = {
    "id" = "subnet-id"
    "name" = "kiran-app-subnet"
  }
}

Running as a root module

git clone https://github.com/maskiran/terraform-azure-app-vnet.git
cd terraform-azure-app-vnet
mv provider provider.tf
cp values-sample values

Using in another module

Create a tf file with the following content

terraform {
  required_providers {
    azurerm = {
      source = "hashicorp/azurerm"
    }
  }
}

provider "azurerm" {
  features {}
}

module "app_vnet" {
  source              = "github.com/maskiran/terraform-azure-app-vnet"
  prefix              = "kiran-app"
  location            = "eastus"
  zones               = ["1"]
  vnet_cidr           = "10.0.0.0/16"
  subnet_bits    = 8
  ssh_public_key_file = "sample.pub"
  instance_size       = "Standard_B1s"
  vm_count_per_zone   = 1
  external_ips        = []
}

You can use variables instead of hard coded values

In the directory where you created the above file, run the following commands

terraform init
terraform apply
