packer-images

Ubuntu and Windows Packer images for Hyper-V builder

Prerequisites

Windows 10 Pro/Server with enabled Hyper-V
Packer

Ubuntu

ubuntu-base

creates base image from ubuntu server .iso
uses packer Hyper-V ISO builder
- creates Generation 2 Images
boots to installer using preseed config
username and password is setup in the boot command passing ssh_username and ssh_password packer template variables
- you can provide either interactively or using environment variables when calling the build script .\ubuntu\Build.ps1
use as baseline for other images.
based on: https://github.com/boxcutter/ubuntu
- made sure the template creates Geneneration 2 VM
- made sure the template does not contantain hard-coded username, password and other sensitive environment variables
- generate the answer ISO automatically on build

ubuntu-server

creates ubuntu server image from ubuntu-base image
adds the Host SSD Public key to the image so you can ssh without password
adds ssh_username to the sudoers so you can sudo without password

ubuntu-desktop

Creates ubuntu desktop image from ubuntu-base image.

customize

vmcx images that can be used on top of ubuntu-server. You can also use vmcx images on top of other vmcx images - see .\ubuntu\customize\ExampleBuilds\BuildGithubAgentDocker.ps1
images include
- docker
- github agent
- k3s
- microk8s
- ansible

Example base, server and desktop Builds

run powershell as local admin
```
cd .\ubuntu\ExampleBuilds\
```
run an example build e.g.
```
BuildUbuntuBase.ps1
```

Example customize Builds

run powershell as local admin
```
cd .\ubuntu\customize\ExampleBuilds\
```
run an example build e.g.
```
BuildUbuntuDocker.ps1
```

Import ubuntu Images to Hyper-V

Run powershell as local admin
```
cd .\ubuntu
```
Run ImportVM.ps1 providing TemplateName that matches one from .\ubuntu\ImagesOutput\. Optionally provide VM name e.g:
```
ImportVM.ps1 -TemplateName ubuntu-server -VmName my-test-server
```

Windows

Windows base

base images for Windows
- 10
- Server 2016
- Serer 2019
start from .ISOs
create Generation 2 Images
- floppy disks are not avialable there so we are forced to create Answer ISO instead that is used for the unattended install
- to do this is used mkisofts.exe
  - the generated ISO is passed to the packer image via secondary_iso_images
- the main script that generates the iso is .\windows\base\baseAnswerIso\GenerateBaseAnswerIso.ps1
  - it generates Autounattend.xml populating the image username, password and other environment specific variables passed to GenerateBaseAnswerIso.ps1
  - copies the helper files used in Autounattend.xml durring the unattended windows install
based on: https://github.com/StefanScherer/packer-windows
- made sure the templates create Geneneration 2 VMs
- made sure templates do not contantain hard-coded username, password and other sensitive environment variables
- generate the answer ISO automatically on build

Windows base - Example builds

run powershell as local admin
```
cd .\windows\base\ExampleBuilds\
```
run an example build e.g.
```
BuildWin2019Core.ps1
```

Windows customize

example vmcx customization image that installs IIS
depends on AnswerIso to provide SysprepUnattend.xml to generalize the image
- see .\windows\answerIso\GenerateSysprepAnswerIso.ps1

Windows customize - Example Build

run powershell as local admin
```
cd .\windows\customize\
```
run an example build e.g.
```
ExampleBuildIis.ps1
```

Import Windows Images to Hyper-V

Run powershell as local admin
```
cd .\windows
```
Run ImportVM.ps1 providing TemplateName that matches one from .\windows\ImagesOutput\. Optionally provide VM name e.g:
```
ImportVM.ps1 -TemplateName win2019-base -VmName my-win2019
```
