Restructure around a single entry point (automations.sh) with a Gum wizard and a self-extracting bundle for repo-less installs. Add scripts/oslib.sh so the provisioning scripts (setup-host, harden-ssh, harden-jumphost, sshuser) run on Alpine/Debian/Alma; seed root keys from globals/. - ntfy SSH-login alerts (user, source IP, key, region, jump target) via pam_exec - daily auto-updates with AUTO_REBOOT=idle (reboots only when no SSH active) and opt-in Alpine stable-branch upgrades - generic + per-deployment cloud-init; Gitea release workflow on tag - README/LICENSE/.gitignore/.gitattributes (force LF); repo URLs -> Gitea

# cloud-init/
|
|
|
|
Generic, distro-agnostic cloud-init templates for standing up a **base host**
|
|
or a **bastion** from scratch. They run on Alpine, Debian, or Alma — the
|
|
runcmd prelude detects the package manager and installs `bash`/`git`/`curl`
|
|
before invoking the scripts.
|
|
|
|
| Template | What it does |
|
|
|----------|--------------|
|
|
| [`base.yml`](base.yml) | Hostname (per the schema) + shared MOTD + seed root keys from `globals/` + SSH hardening (`harden-ssh.sh`). |
|
|
| [`jumphost.yml`](jumphost.yml) | Same base, but bastion hardening (`harden-jumphost.sh`) with an `ssh-admins`/`ssh-jumpers` split and a ProxyJump whitelist. |
|
|
|
|
These are for the **host itself**. To stand up a Docker stack on a host,
|
|
use the per-deployment `cloud-init.yml` under `deployments/<name>/` instead
|
|
(those clone the repo and run the stack's `deploy.sh`).
|
|
|
|
## Usage
|
|
|
|
1. Copy the template, fill in `REPO_URL`, `HOST` (`<svc>-<n>`, e.g. `sto-1`),
|
|
and the other values at the top of the `runcmd` block.
|
|
2. Paste it as the instance's **user-data** when creating the VM.
|
|
3. On first boot the host names itself, installs the MOTD, seeds admin keys
|
|
from `globals/`, and hardens SSH.
|
|
|
|
Hostnames follow [`../globals/Network Domain Name Schema.md`](../globals/Network%20Domain%20Name%20Schema.md);
|
|
our VMs skip the region code and use `srvno.de` as the base.
|
|
|
|
> The harden scripts print a generated root private key to stdout, which lands
|
|
> in the cloud provider's serial/console log. Capture it there, or rely on the
|
|
> keys seeded from `globals/authorized_keys` (or `SSH_KEYS_URL`) and ignore it.
