Bootstrapping an Azure Linux VM with a Bash script for AzureRM v1.x and AzureRM v2.x. This sample combines terraform and powershell to deploy an Azure Automation account with runbooks and schedules in order to manage VM off-hours state. Terraform uses the provisioner Connection for connecting to the Azure VM using the SSH key. Create hub virtual network appliance 5. Apt or Yum on Linux works with packages that are built for either Debian or Fedora based distros. To get started, create a Files folder with 2 files inside, FirstLogonCommands.xml and winrm.ps1. Step4: Go ahead and Apply it with Terraform apply. We can use a nano editor to create the Infrastructure as Code script for the Virtual Machine using Terraform. To reuse and share components across projects and to better organize large projects, you can create modules. license_type - (Optional) Specifies the BYOL Type for this Virtual Machine. Terraform is used to create Azure resources that will run the powershell runbook. Anything specific you would like to see? Terraform is a software that enables you provision infrastructure using code. It supports existing ssh keys or generates ssh key pairs if required for Linux VM's. This script needs to run on an Azure VM. It codifies infrastructure in configuration files that describe the desired state for your topology. Once the Azure Cloud Shell opens up, select Bash. To do this, you'd need to run the following command locally on each VM: Enable-PSRemoting -Force Let's build a custom script extension to do this. Terraform is a tool for building, changing, and versioning infrastructure. Wait until the runbook testing is completed, and you should see the output stream returned. Ensure you have setup and authorised both terraform and Azure cli2 correctly for your subscription (you'll need read access - and also access (list, read) to any KeyVaults you use) Download 'az2tf' or clone from github into an empty directory on your terraform vm. VM Custom Script extension lets you scripts inside the VM using the Local System Account. >>Your runbook is empty. Run PowerShell script in Windows machines and Bash script in Linux machines. With the Azure Custom Script extension we can execute scripts on Azure VMs for post deployment configuration, software installation, or any other configuration / management task. This cannot be combined with script or scripts. In this lab, you will use modules shared on the public Terraform Registry as well as a module that you create to provision a web server virtual machine in Azure. Native (Mac/Linux) Prerequisites Ruby (~> 2.3) Bundler (~> 1.15) Terraform (~> 0.11.0) Quick Run Let us start creating scripts to create an Azure Virtual Machine. It looks like the problem is in your script and not in the terraform file per se Problem When you run your install_nginx_ubuntu.sh script in an Ubuntu VM, this is the output that's happening on the box (just showing the last part): 0 upgraded, 14 newly installed, 0 to remove and 162 not upgraded. Set tags on Azure VM The good news is, based on the values set on the tags, the Function will automate the stop and start for the VM. The easiest solution is the CustomScriptExtension. Part 1 is below and is all you need to stop and start VMs on a schedule using a quick setup and easy script (provided below). Step2: Initialize Terraform. on top of them. These 2 files will run at the first launch of the machine, to configure the WinRM, to connect remotely via the Provider. Heres a couple examples of Input Variables defined a Terraform project: variable "environment" { type = string}variable "location" { type = string default = "eastus" description = "The Azure Region to deploy resources."} There are a few basic properties that can be defined within the variable block. Creating the disk and attaching it to the VM can be achieved with Terraform. To be added. We provide 2 ways to build, run, and test the module on a local development machine. Can be run using Azure portal, REST API, Azure CLI, or PowerShell Quickly run a script and view output and repeat as needed in the Azure portal. README Specifying user-data in Terraform Giving an EC2 instance user-data in Terraform is quite easy For example, the Azure provider requires the 'az' binary to be available in the system The Custom Script Extension integrates with Azure Resource Manager templates, and can be run using the Azure CLI, PowerShell, Azure portal, or the Azure.README Specifying user-data in Terraform Giving . Please note that you can have different values (times) on different virtual machines, and since the function will trigger hourly, it will stop and start the VM based on the values you enter here. It is a powerful tool that supports multi-cloud like Amazon Web Services, Microsoft Azure, and Google Cloud Platform, or on-prem . This is not required for Windows deployments. Step3: Pre-Validate the change - A pilot run. When you run terraform apply, Terraform reads any configuration files you have in the directory and prompts you for confirmation. Step1: Creating a Configuration file for Terraform AWS. bootstrapping example environments including CI/CD, config management server, Terraform Cloud, etc. advanced syntax (e.g. Build and test modules in Azure with the Azure Terraform extension for Visual Studio Code, providing Terraform command support, resource graph visualisation, and Azure Cloud Shell integration directly within Visual Studio Code. See AWS, Azure and GCP. Pass it to custom script extension to be executed. Execute the following command to open a nano editor and create a file named myterraformscript.tf. nano myterraformscript.tf This article details how to use the Custom Script Extension from the Azure CLI, and how to run the extension by using an Azure Resource Manager template.
