Terraform provider for libvirt

alpha Build Status


This is a terraform provider that lets you provision servers on a libvirt host via Terraform.

Table of Content

Website Docs

Introduction & Goals

This project exists:

  • To allow teams to get the benefits Software Defined Infrastructure Terraform provides, on top of classical and cheap virtualization infrastructure provided by Linux and KVM This helps in very dynamic DevOps, Development and Testing activities.
  • To allow for mixing KVM resources with other infrastructure Terraform is able to manage

What is NOT in scope:

  • To support every advanced feature libvirt supports

    This would make the mapping from terraform complicated and not maintanable. See the How to contribute section to understand how to approach new features.

Downloading

Builds for openSUSE, CentOS, Ubuntu, Fedora are created with openSUSE's OBS. The build definitions are available for both the stable and master branches.

Using published binaries/builds

Using packages

Follow the instructions for your distribution:

Building from source

Requirements

  • Terraform
  • Go (to build the provider plugin)
  • libvirt 1.2.14 or newer development headers
  • cgo is required by the libvirt-go package. export CGO_ENABLED="1"

This project uses go modules to vendor all its dependencies.

You do not have to interact with modules since the vendored packages are already included in the repo.

Ensure you have the latest version of Go installed on your system, terraform usually takes advantage of features available only inside of the latest stable release.

You need also need libvirt-dev(el) package installed.

Building The Provider

Clone repository to: $GOPATH/src/github.com/dmacvicar/terraform-provider-libvirt

mkdir -p $GOPATH/src/github.com/dmacvicar; cd $GOPATH/src/github.com/dmacvicar
git clone https://github.com/dmacvicar/terraform-provider-libvirt.git

Enter the provider directory and build the provider

cd $GOPATH/src/github.com/dmacvicar/terraform-provider-libvirt
make install

If you are using Go >= 1.11, you don't need to build inside GOPATH:

export GO111MODULE=on
export GOFLAGS=-mod=vendor
go mod vendor
make install

You will now find the binary at $GOPATH/bin/terraform-provider-libvirt.

Windows

To build it on Windows (64bit) one can use MinGW64 (http://www.msys2.org/)

Install Golang on Windows
Clone terraform-provider-libvirt repository
Open MinGW64 Console

pacman -S mingw-w64-x86_64-libvirt
export PATH=$PATH:/c/Go/bin
pacman -S mingw-w64-x86_64-pkg-config
pacman -S mingw-w64-x86_64-glib2
pacman -S mingw-w64-x86_64-dbus-glib
pacman -S mingw-w64-x86_64-libssh
pacman -S mingw-w64-x86_64-yajl
export GO111MODULE=on
export GOFLAGS=-mod=vendor
go install

Installing

  • Check that libvirt daemon 1.2.14 or newer is running on the hypervisor (virsh version --daemon)
  • mkisofs is required to use the CloudInit

Copied from the Terraform documentation:

At present Terraform can automatically install only the providers distributed by HashiCorp. Third-party providers can be manually installed by placing their plugin executables in one of the following locations depending on the host operating system:

On Linux and unix systems, in the sub-path .terraform.d/plugins in your user's home directory.

On Windows, in the sub-path terraform.d/plugins beneath your user's "Application Data" directory.

terraform init will search this directory for additional plugins during plugin initialization.

Using the provider

Here is an example that will setup the following:

  • A virtual server resource

(create this as libvirt.tf and run terraform commands from this directory):

provider "libvirt" {
    uri = "qemu:///system"
}

You can also set the URI in the LIBVIRT_DEFAULT_URI environment variable.

Now, define a libvirt domain:

resource "libvirt_domain" "terraform_test" {
  name = "terraform_test"
}

Now you can see the plan, apply it, and then destroy the infrastructure:

$ terraform init
$ terraform plan
$ terraform apply
$ terraform destroy

Look at more advanced examples here

Using multiple hypervisors / provider instances

You can target different libvirt hosts instantiating the provider multiple times. Example.

Using qemu-agent

From its documentation, qemu-agent:

It is a daemon program running inside the domain which is supposed to help management applications with executing functions which need assistance of the guest OS.

Until terraform-provider-libvirt 0.4.2, qemu-agent was used by default to get network configuration. However, if qemu-agent is not running, this creates a delay until connecting to it times-out.

In current versions, we default to not to attempt connecting to it, and attempting to retrieve network interface information from the agent needs to be enabled explicitly with qemu_agent = true, further details here. Note that you still need to make sure the agent is running in the OS, and that is unrelated to this option.

Note: when using bridge network configurations you need to enable the qemu_agent = true. otherwise you will not retrieve the ip adresses of domains.

Be aware that this variables may be subject to change again in future versions.
