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:

  • v1.8.0 added vswitch and portgroup resources.
  • v1.7.1 added 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 & Import Resource Pools.
  • Terraform will Create, Destroy, Update & Import Guest VMs.
  • Terraform will Create, Destroy, Update & Import Extra Storage for Guests.
  • Terraform will Create, Destroy, Update & Import vSwitches.
  • Terraform will Create, Destroy, Update & Import Port Groups.

This is a provider! NOT a provisioner.

  • This plugin does not configure your guest VM, it creates it.
  • To configure your guest VM after it's built, you need to use a provisioner.
    • Refer to Hashicorp list of provisioners: https://www.terraform.io/docs/provisioners/index.html
  • To help you get started, there is are examples in a separate repo I created. You can create a Pull Request if you would like to contribute.

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
    • Download and install Terraform on your local system using instructions from https://www.terraform.io/downloads.html.
  • Automatic install
    • Add the requiredproviders block to your terraform project. ``` terraform { requiredversion = ">= 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 } } } ```
  • Manual installation (Terraform 0.11.x or 0.12.x only)
    • Download pre-built binaries from https://github.com/josenk/terraform-provider-esxi/releases. Place a copy of it in your path or current directory of your terraform project.

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 ovfsource & clonefrom_vm

  • clonefromvm 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.
    • clonefromvm = "myresourcegroup/mysourcevm"
  • ovf_source clones from sources on your local hard disk or a URL.
    • A local ova, ovf, vmx file. See known issues (below) with vmx sources.
    • URL specifying a remote ova.
    • For example, Ubuntu cloud-images: https://cloud-images.ubuntu.com/trusty/current/trusty-server-cloudimg-amd64.ova
  • 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.
  • ovfsource & clonefrom_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 gueststartuptimeout or guestshutdowntimeout to 0 (zero). It's valid, however it will be changed to default values by terraform.
