Automatic install post procedures

[RazZinger]

Hi,
Proxmox VE version: 8.4.1
Im creating custom.iso with answer.toml as following:
===
[global]
keyboard = "en-us"
country = "us"
fqdn = "{{MACHINE_NAME}}.proxmox.local"
mailto = "{{MAIL_TO}}"
timezone = "UTC"
root-password = "{{ROOT_PW}}"

[network]
source = "from-answer"
cidr = "{{IP}}"
gateway = "{{GATEWAY}}"
dns = "{{DNS}}"
filter.ID_NET_NAME = "ens2f0np0"

[disk-setup]
filesystem = "ext4"
disk-list = ["nvme0n1"]
===

How can I execute automatic post install procedure to update /etc/network/interfaces file with VLAN's and Bridges
Until interfaces configured, dont have ssh access, only iLO access

Hi,

you probably want to use the first-boot hook: https://pve.proxmox.com/wiki/Automated_Installation#First_Boot_Hook_Section

This enables you to run a script on the first boot after the installation, where you can customize the installation further as needed.

Thank you Christoph
cant find example when source = "from-iso"

It's in the linked documentation:

When using from-iso, the executable must be specified when preparing the ISO using proxmox-auto-install-assistant prepare-iso --on-first-boot path/to/file.sh

Where the script (as given in the example as path/to/file.sh can be a arbitrary executable (don't forget the shebang for scripts!).
This will then be run on boot (according to the ordering specified) as root, meaning you can then in it e.g. create a new file under /etc/network/interfaces.d, whatever you need.

Probably I'm missing something, please take a look
