Terraform Modules

Compilation of Terraform modules used for different tasks.

The contents of this repository are for EXAMPLE PURPOSE ONLY and should not be used in an an environment without prior user validation and testing.

Requirements

Modules Included

  • modules/az_resource_group : Used to create an Azure Resource Group along with an associated VNET and NSG.
  • modules/az_aks_cluster_linux : Used to create an Azure Managed Kubernetes Service. Relies upon an existing Resource Group and VNET.
  • modules/az_vm_linux : Used to create a Linux Azure Virtual Machine (Default Ubuntu 22.04). Relies upon an existing Resource Group and VNET.

Other Examples

Usage

Azure Resource Group - az_resource_group

Resources Created:

  • Azure Resource Group

  • Azure Virtual Network (VNET) with associated Subnet.

  • Azure Network Security Group (NSG) with rules allowing ssh (ports 22 and 122), winrm & rdp.

    graph
subgraph Azure Resource Group
  subgraph Virtual-Network
    s(Subnet)
  end
  subgraph Network-Security-Group
    r1(rule)
    r2(rule)
  end
end

    Loading

Usage:

  • Perform work from the az_resource_group top-level directory.
  • verify that Azure CLI is installed and you are properly authenticated (az login).
  • Rename main.tf.example to be main.tf and update all values.
  • run terraform init
  • Execute terraform plan to confirm there are no errors.
  • Execute terraform apply to build the infrastructure. This will create with module source of modules/az_resource_group.
  • Execute terraform destroy when completed to clean-up any resources created.

Azure AKS Cluster (Linux) - az_aks_cluster_linux

The az_aks_cluster_linux module requires that an Azure Resource Group is already created. Use the az_resource_group module to create a Resource Group, if needed.

graph
subgraph Azure Resource Group
  subgraph AKS
    n(NodePool)
  end
end

Usage:

  • Perform work from the az_aks_cluster_linux top-level directory.
  • verify that Azure CLI is installed and you are properly authenticated (az login).
  • Rename main.tf.example to be main.tf and update all values.
  • run terraform init
  • Execute terraform plan to confirm there are no errors.
  • Execute terraform apply to build the infrastructure. This will create with module source of modules/az_aks_cluster_linux.
  • Execute terraform destroy when completed to clean-up any resources created.

Azure AKS Cluster Actions Runner Controller (ARC) - az_aks_cluster_arc

The az_aks_cluster_arc is used to build an Azure Managed Kubernetes Service cluster and then deploy Actions Runner Controller(ARC). This example will create an ARC deployment and register a Webhook on the target Organization(s).

Currently only works with GitHub Enterprise Server(GHES)

graph
subgraph AKS
  subgraph NodePool
    arc1(Arc Pod org1)
    arc2(Arc Pod org2)
    arcx(Arc Pod orgX)
    wh(Webhook Service)
  end
end

subgraph GHES
  org1 & org2 & orgX -. webhook .-> wh
  arc1
  arc2
  arcx
end

Loading

Usage:

  • Perform work from the az_aks_cluster_arc top-level directory.
  • Verify that Azure CLI is installed and you are properly authenticated (az login).
  • Verify that kubectl is installed.
  • Have a target Organization (or Organizations) created along with a Personal Access Token properly scoped for Actions Runner Controller.
  • Rename main.tf.example to be main.tf and update all values.
  • run terraform init
  • Execute terraform plan to confirm there are no errors.
  • Execute terraform apply to build the infrastructure. This will create with module source of modules/az_aks_cluster_linux along with resources defined locally within main.tf
  • Verify that the ARC runners were created and are registered properly to the target Organization(s) and that the webhook(s) status is Active without errors.
  • Execute terraform destroy when completed to clean-up any resources created.

Azure Virtual Machine (Linux) - az_vm_linux

The az_vm_linux module requires that an Azure Resource Group is already created. Use the az_resource_group module to create a Resource Group, if needed.

Usage:

  • Perform work from the az_vm_linux top-level directory.
  • verify that Azure CLI is installed and you are properly authenticated (az login).
  • Rename main.tf.example to be main.tf and update all values.
  • run terraform init
  • Execute terraform plan to confirm there are no errors.
  • Execute terraform apply to build the infrastructure. This will create with module source of modules/az_vm_linux.
  • Execute terraform destroy when completed to clean-up any resources created.
