Terraform 0.12 – Module for creating Azure virtual machine

Create terraform application and get SubcriptionID,TenantID,ApplicationID,Client Secret and Object ID as described in this post.

Add Azure client ID,Client Secret, subscription ID and environmental variables

For linux:

export ARM_CLIENT_ID=key
export ARM_CLIENT_SECRET=key
export ARM_SUBSCRIPTOIN=key
export ARM_TENANT_ID=key

Download files from here

Open \module\vm\example\terraform.tfvars and add azure_application_id and azure_tenant_id

azure_application_id = "your Object ID"
azure_tenant_id="Your tenant ID"

Edit C:\terraform\modules\vm\example\main.tf

There are 4 modules:

• azure_vnet: creates Virtual network (10.0.0.0/16) and 1 subnet (10.0.1.0/24), output is subnet name
• azure_key_vault:creates Azure vault, key and secret, it outputs vault URL,vault ID, key name, key version and secret ID
• azure_vm: creates Azure VM, there is option to chose OS (linux/windows), whether OS disk will be encrypted, number of VM’s, it adds one data disk and arbitrary number of managed disks
• azure_rg: creates resource group for all above resources

 

#Resource group
