Splits the repo into Stage 1 (base host config/hardening, applies to any node) and Stage 2 (future HA/Ceph cluster, deferred - pve1's mini-PC hardware can't support the assumed split-disk/multi-NIC layout). Adds the Stage 1 toolset: firewall deploy, named admin user creation, unattended security upgrades, subscription-nag removal (with an apt hook so the patch survives package updates), and a read-only audit script. Fixes switch-to-no-subscription-repo.sh, which only handled the legacy .list format and silently no-op'd against PVE 9's deb822 .sources files; it now removes enterprise sources outright rather than commenting them out. Shared logic (root check, idempotent file writes, backups) factored into scripts/lib/common.sh. Ran the full sequence against pve1 via scripts/bootstrap.sh + create-admin-user.sh; scripts/audit.sh confirms all checks pass.

# Proxmox Configuration
|
|
|
|
Base configuration and hardening toolset for Proxmox VE hosts, plus planning
|
|
docs for eventually growing this into a 3-node HA/Ceph cluster. See
|
|
`docs/00-overview.md` for the staging: **Stage 1** (base config/hardening,
|
|
applies to any host — active) vs. **Stage 2** (multi-node HA/Ceph — future,
|
|
deferred).
|
|
|
|
## Goals
|
|
|
|
- Stage 1: a reusable, idempotent base-hardening toolset (`scripts/`) that
|
|
can be run against any new Proxmox host — repo/updates, SSH, firewall, PVE
|
|
user/access hardening — verified with `scripts/audit.sh`.
|
|
- Stage 2 (future): 3-node cluster, quorum via corosync, HA-managed VMs
|
|
backed by Ceph. Needs dedicated hardware node 1 (`pve1`, an ASUS PN53 mini
|
|
PC) doesn't have — see `docs/01-hardware-node1.md`.
|
|
|
|
## Repo layout
|
|
|
|
- `docs/` — planning docs: hardware layout, storage migration, networking,
|
|
security hardening. Read `docs/00-overview.md` first.
|
|
- `scripts/` — scripts to apply configuration on a node (SSH hardening, repo
|
|
switch, firewall, updates, etc). Idempotent, safe to re-run.
|
|
`scripts/bootstrap.sh` runs the full Stage 1 sequence end to end;
|
|
`scripts/audit.sh` verifies it (read-only). `scripts/lib/` holds shared
|
|
helpers (`common.sh`) sourced by the other scripts.
|
|
- `config/` — reference config files/snippets to drop onto a node (firewall
|
|
rules, sshd config, etc.).
|
|
|
|
## Quick start (Stage 1, on a fresh node)
|
|
|
|
```
|
|
MGMT_CIDR=192.168.2.0/24 ./scripts/bootstrap.sh
|
|
./scripts/create-admin-user.sh <username>
|
|
# then enable 2FA for that user + root@pam via the web UI
|
|
./scripts/audit.sh
|
|
```
|
|
|
|
## Status
|
|
|
|
`pve1` built (ASUS PN53 mini PC, ZFS mirror boot+VM storage, single
|
|
2.5GbE NIC) and already running production VMs/CTs. Stage 1 base
|
|
hardening applied and verified (`scripts/audit.sh` all green): enterprise
|
|
repos removed, SSH key-only + fail2ban, unattended security upgrades,
|
|
PVE firewall (mgmt-only), subscription nag disabled, named admin user
|
|
(`wayne@pve`) created. Remaining manual step: enable 2FA/TOTP for
|
|
`wayne@pve` and `root@pam` via the web UI. Stage 2 (cluster/Ceph) not
|
|
started — needs nodes 2/3 on hardware that can actually support it.
