Terraform Provider

Requirements

  • Terraform 0.10.1+
  • Go 1.11+ (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

In general, you don't normally need to build the provider. A release can be downloaded from github, or can automatically be downloaded with terraform 0.13.

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

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

Clone repository to: $GOPATH/src/github.com/terraform-providers/terraform-provider-esxi

mkdir $HOME/go
export GOPATH="$HOME/go"

go get -u -v golang.org/x/crypto/ssh
go get -u -v github.com/hashicorp/terraform
go get -u -v github.com/josenk/terraform-provider-esxi

cd $GOPATH/src/github.com/josenk/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 0.13 support. This provider is now in the terraform registry.

https://registry.terraform.io/providers/josenk/esxi

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.

This is a provider! NOT a provisioner.

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...

https://www.vagrantup.com/intro/vs/terraform.html https://github.com/josenk/terraform-provider-esxi https://github.com/josenk/vagrant-vmware-esxi

Why this plugin?

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

How to install

  • Install terraform
  • Automatic install
    • Add the required_providers block to your terraform project.
terraform {
  required_version = ">= 0.13"
  required_providers {
    esxi = {
      source = "registry.terraform.io/josenk/esxi"
      #
      # For more information, see the provider source documentation:
      # https://github.com/josenk/terraform-provider-esxi
      # https://registry.terraform.io/providers/josenk/esxi
    }
  }
}

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.
terraform {
  required_version = ">= 0.12"
}

provider "esxi" {
  esxi_hostname      = "esxi"
  esxi_hostport      = "22"
  esxi_hostssl       = "443"
  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

Using ovf_source & clone_from_vm

  • clone_from_vm clones from sources on the esxi host.
    • The source VM must be powered off.
    • If the source VM is stored in a resource group, you must specify the path, for example.
      • clone_from_vm = "my_resource_group/my_source_vm"
  • ovf_source clones from sources on your local hard disk or a URL.
  • If neither is specified, then a bare-metal VM will be created. There will be no OS on this vm. If the VM is powered on, it will default to a network PXE boot.
  • ovf_source & clone_from_vm are mutually exclusive.

Known issues with vmware_esxi

  • Using a local source vmx files should not have any networks configured. There is very limited network interface mapping abilities in ovf_tools for vmx files. It's best to simply clean out all network information from your vmx file. The plugin will add network configuration to the destination vm guest as required.
  • terraform import cannot import the guest disk type (thick, thin, etc) if the VM is powered on and cannot import the guest ip_address if it's powered off.
  • Only numvcpus are supported. numcores is not supported.
  • Doesn't support CDrom or floppy.
  • Doesn't support Shared bus Interfaces, or Shared disks
  • Using an incorrect password could lockout your account using default esxi pam settings.
  • Don't set guest_startup_timeout or guest_shutdown_timeout to 0 (zero). It's valid, however it will be changed to default values by terraform.
