| # Automatic OS Installs |
| |
| If you are building from a brand-new and unconfigured operating system |
| image, Packer will need you to perform the operating system install before it |
| can connect to and configure your image using its provisioners. Most operating |
| system distributions have a mechanism for performing the normally-interactive |
| installation in an automated way. For Debian operating systems, this is done |
| using a preseed file; for Windows, it's done using an Autounattend.xml. We have |
| compiled some simple guides here for common operating system distributions. |
| |
| These guides are meant to give you a quick introduction to how to use automated |
| installation answer files in order to perfom those installs; we don't mean to |
| be a comprehensive guide on each operating system, but we hope to give you |
| enough context to be able to more easily find any further information you need. |
| |
| Refer to the instructions for your operating system. |
