Terraform Provider

Requirements

  • Terraform 0.10.1+
  • Go 1.9 (to build the provider plugin)
  • ovftool from VMware. NOTE: ovftool installer for windows doesn't put ovftool.exe in your path. You will need to manually set your path.
  • You MUST enable ssh access on your ESXi hypervisor.
  • Google 'How to enable ssh access on esxi'
  • In general, you should know how to use terraform, esxi and some networking...
  • You will most likely need a DHCP server on your primary network if you are deploying VMs with public OVF/OVA/VMX images. (Sources that have unconfigured primary interfaces.)
  • The source OVF/OVA/VMX images must have open-vm-tools or vmware-tools installed to properly import an IPaddress. (you need this to run provisioners)

Building The Provider

You first must set your GOPATH. If you are unsure, please review the documentation at.

https://github.com/golang/go/wiki/SettingGOPATH

Clone repository and build

git clone github.com/josenk/terraform-provider-esxi
cd terraform-provider-esxi
CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -a -ldflags '-w -extldflags "-static"' -o terraform-provider-esxi_`cat version`

sudo cp terraform-provider-esxi_`cat version` /usr/local/bin

Terraform-provider-esxi plugin

  • This is a Terraform plugin that adds a VMware ESXi provider support. This allows Terraform to control and provision VMs directly on an ESXi hypervisor without a need for vCenter or VShpere. ESXi hypervisor is a free download from VMware!

https://www.vmware.com/go/get-free-esxi

  • If you don't know terraform, I highly recommend you read through the introduction on the hashicorp website.

https://www.terraform.io/intro/getting-started/install.html

  • VMware Configuration Maximums tool.

https://configmax.vmware.com/guest

What's New:

  • Terraform can import existing Guest VMs, Virtual Disks & Resource pools by name. See wiki page for more info.

https://github.com/josenk/terraform-provider-esxi/wiki/How-to-import

  • Added support for GuestInfo. (Thanks for the contribution silasb.)
    • This adds great provisioning options like Ignition and Cloud-Init!

Features and Compatibility

  • Source image can be a clone of a VM or local vmx, ovf, ova file. This provider uses ovftool, so there should be a wide compatibility.
  • Supports adding your VM to Resource Pools to partition CPU and memory usage from other VMs on your ESXi host.
  • Terraform will Create, Destroy, Update & Read Resource Pools.
  • Terraform will Create, Destroy, Update & Read Guest VMs.
  • Terraform will Create, Destroy, Update & Read Extra Storage for Guests.

Vagrant vs Terraform.

If you are using vagrant as a deployment tool (infa as code), you may want to consider a better tool. Terraform. Vagrant is better for development environments, while Terraform is better at managing infrastructure. Please give my terraform plugin a try and give me some feedback. What you're trying to do, what's missing, what works, what doesn't work, etc...

Why this plugin?

Not everyone has vCenter, vSphere, expensive APIs... These cost $$$. ESXi is free!

How to install

Download and install Terraform on your local system using instructions from https://www.terraform.io/downloads.html. Clone this plugin from github, build and place a copy of it in your path or current directory of your terraform project. Or download pre-built binaries from https://github.com/josenk/terraform-provider-esxi/releases.

How to use and configure a main.tf file

  1. cd SOMEDIR
  2. vi main.tf # Use the contents of this example main.tf as a template. Specify provider parameters to access your ESXi host. Modify the resources for resource pools and guest vm.
provider "esxi" {
  esxi_hostname      = "esxi"
  esxi_hostport      = "22"
  esxi_username      = "root"
  esxi_password      = "MyPassword"
}

resource "esxi_guest" "vmtest" {
  guest_name         = "vmtest"
  disk_store         = "MyDiskStore"

  #
  #  Specify an existing guest to clone, an ovf source, or neither to build a bare-metal guest vm.
  #
  #clone_from_vm      = "Templates/centos7"
  #ovf_source        = "/local_path/centos-7.vmx"

  network_interfaces = [
    {
      virtual_network = "VM Network"
    },
  ]
}

Basic usage

  1. terraform init
  2. terraform plan
  3. terraform apply
  4. terraform show
  5. terraform destroy
