What is packer-CentOS7 ?

packer-CentOS7 is a set of configuration files used to build an automated CentOS 7 virtual machine images using Packer. This Packer configuration file allows you to build images for VMware Workstation and Oracle VM VirtualBox.

Prerequisites

• Packer
  • https://www.packer.io/intro/getting-started/install.html
• A Hypervisor
  • VMware Workstation
  • Oracle VM VirtualBox

How to use Packer

Commands to create an automated VM image:

To create a CentOS 7 VM image using VMware Workstation use the following commands:

cd c:\packer-CentOS7
packer build -only=vmware-iso centos7.json
packer build -only=vmware-iso centos7_uefi.json

To create a CentOS 7 VM image using Oracle VM VirtualBox use the following commands:

cd c:\packer-CentOS7
packer build -only=virtualbox-iso centos7.json
packer build -only=virtualbox-iso centos7_uefi.json

If you omit the keyword "-only=" both the Workstation and Virtualbox VMs will be created.

By default the .iso of CentOS 7 is pulled from http://miroir.univ-paris13.fr/centos/7.9.2009/isos/x86_64/CentOS-7-x86_64-NetInstall-2009.iso

You can change the URL to one closer to your build server. To do so change the "iso_url" parameter in the "variables" section of the centos7.json file.

{
  "variables": {
      "iso_url": "http://miroir.univ-paris13.fr/centos/7.9.2009/isos/x86_64/CentOS-7-x86_64-NetInstall-2009.iso"
}
