The header still told readers to paste the raw GitHub URL, left over from before we confirmed provider user-data fields run pasted/imported content directly rather than fetching a URL.

# cloud-init.sh — payload for a cloud provider's "install script" / user-data
|
|
# field (IONOS Cloud Server image deploy, DigitalOcean droplet user-data,
|
|
# Hetzner Cloud user-data, etc). The provider runs this as root, unattended,
|
|
# with no TTY, while the box is still being provisioned — before you have
|
|
# ever logged in.
|
|
#
|
|
# It deliberately does NOT run the interactive wizard itself (there's no
|
|
# terminal for whiptail to talk to yet). Instead it does two things:
|
|
#
|
|
# 1. Clones this repo to /root/ubuntu-post-install (pulls if already there).
|
|
# 2. Installs a one-shot /etc/profile.d hook that launches setup.sh —
|
|
# the normal whiptail service menu — the first time you actually log
|
|
# in over SSH, then deletes itself so it never fires again.
|
|
#
|
|
# End result: the provider boots Ubuntu 24.04, this runs in the background,
|
|
# and by the time you SSH in the checklist menu is sitting there waiting —
|
|
# the same experience as running bootstrap.sh by hand, just already started.
|
|
#
|
|
# Usage: paste this whole file's contents into the provider's install-script /
|
|
# user-data field (or use an "import from file" option if it has one).
|
|
# User-data fields run the content you give them directly — they don't fetch
|
|
# a URL — so paste the script itself, not a link to it.
|
|
#
|
|
# Assumes the provider logs you in as root (the default for IONOS Cloud
|
|
# Server, DigitalOcean droplets, and Hetzner Cloud server images). If you've
|
|
# provisioned a separate non-root sudo user instead, the hook won't reach
|
|
# you automatically — SSH in and run:
|
|
# sudo bash /root/ubuntu-post-install/setup.sh
