MinIO's open-source edition is de-prioritised (console removed, commercial
pivot), so swap the off-cluster S3 backup target on the Proxmox host to
versitygw v1.7.0 (github.com/versity/versitygw) — a maintained Go S3 gateway
serving a POSIX filesystem as S3.
Rename role minio_backup_target -> s3_backup_target and playbook backup-minio
-> backup-s3. The role now:
- decommissions any pre-existing MinIO (service/binary/env/mc-client/user/
object-layout), KEEPING the ZFS dataset Storage/k3s-backups and its mount
- installs the pinned, checksummed versitygw binary (fetched+extracted on the
controller, host has no internet), a dedicated versitygw system user, and a
Type=simple hardened systemd unit running the posix backend rooted at
/mnt/Storage/k3s-backups/data, bound to 192.168.1.9:9000 (same endpoint),
plain HTTP / path-style
- ensures the dataset has xattr=sa (versitygw stores object metadata in xattrs)
- pre-creates the velero + cnpg buckets (bucket == top-level subdir)
Credentials are REUSED: versitygw's ROOT key is set to the same scoped
access_key/secret the cluster already uses, so endpoint + key + secret + bucket
names are byte-identical to the old MinIO target. The GitOps SOPS secret
(platform/backup/minio-credentials.sops.yaml) and all cluster-side Velero/CNPG
config need ZERO change. The vaulted group_vars now expose
s3_backup_target_access_key/_secret_key (same values, MinIO root creds retired).
Verified live on the Proxmox host: versitygw active+enabled on 192.168.1.9:9000,
MinIO fully removed, dataset intact; SigV4 ListBuckets with the reused key
returns velero+cnpg; a throwaway in-cluster pod reaches http://192.168.1.9:9000
(versitygw S3 response). Re-run is idempotent (no host changes).

infra/ — node provisioning and the toolchain
OpenTofu (Proxmox VE) + cloud-init + Ansible bring up the 3-node k3s/Cilium dev cluster.
Spec: ../home-network-k3s/docs/02-environments-and-provisioning.md.
| Path | What |
|---|---|
tofu/ |
The "Create" stage: 3 cloud-init'd VMs on the Proxmox box (bpg/proxmox provider) |
cloud-init/ |
First-boot baseline shipped as a Proxmox user-data snippet |
ansible/ |
The "Baseline"/"Configure" stages: k3s HA, Cilium, kube-vip, the VPN egress gateway |
devcontainer/ |
The pinned toolchain (tofu, ansible, sops, age, flux, kubectl, helm and the whole CI gate toolchain) |
cluster.sh |
RETIRED — drove the old libvirt VMs; does not work against Proxmox |
PHASE1-STATUS.md |
Current state of the cluster and how to reconnect to it |
PHASE1-SCOPE.md |
Historical Phase-1 scoping doc (libvirt era — superseded) |
Where the cluster actually lives
The dev cluster is not on this workstation. It runs on a Proxmox VE host; the nodes sit on the Proxmox LAN and are reached across a pfSense NAT:
| Nodes | k3s-dev-1/2/3 at 192.168.1.50/.51/.52 — 6 vCPU, 16 GiB, Debian 12, k3s v1.31.5 |
| kube-API | kube-vip VIP 192.168.1.49:6443, reached from the workstation via NAT 192.168.2.50:6443 |
| Node SSH | pfSense NAT 192.168.2.102:2250/2251/2252 → node :22 (Ansible only) |
| Ingress VIP | 192.168.1.53 (Cilium L2, shared Gateway); .53–.60 reserved for LB VIPs |
The earlier libvirt/KVM cluster on 10.73.0.0/24 is retired. Any doc or command referencing
virsh, qemu:///system, or 10.73.0.x for the cluster is historical.
