I am trying to build an image using packer. It’s able to set up everything correctly and ran the cloud init using the user-data file I provided. After setting up everything it reboots, and that’s where the problem is. It fails and gives me an error saying I need to provide a boot device.
Can someone tell me what I am missing in my packer script or the user-data script that is causing this?
Here is my packer script:
source "hyperv-iso" "ubuntu-focal-griffin" {
# Booting
boot_command = [
"<wait5><esc><esc><esc>",
"<enter><wait>",
"/casper/vmlinuz ",
"initrd=/casper/initrd ",
"autoinstall ",
"<enter>"
]
