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 withscripts/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 — seedocs/01-hardware-node1.md.
Repo layout
docs/— planning docs: hardware layout, storage migration, networking, security hardening. Readdocs/00-overview.mdfirst.scripts/— scripts to apply configuration on a node (SSH hardening, repo switch, firewall, updates, etc). Idempotent, safe to re-run.scripts/bootstrap.shruns the full Stage 1 sequence end to end;scripts/audit.shverifies 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.
