Add ACME DNS-01 (TXT-record) validation alongside the existing HTTP-01,
for internal/isolated clusters with no public port 80 and for wildcard
certificates. Opt-in via a global kill-switch (default off); HTTP-01 is
byte-for-byte unchanged, with zero agent or rendered-config changes.
- Pluggable DNS provider interface (Manual + Cloudflare). Per-account
credentials are Fernet-encrypted at rest, verified on save, and never
returned by the API or written to logs/events/error_detail.
- Non-blocking per-cycle orchestrator: publish (CAS) -> propagation grace
(across cycles, no in-loop sleep) -> respond -> finalize/download, with a
bounded fresh-order retry chain (1 original + 3 retries) on propagation lag.
- Manual flow: user publishes the TXT record and confirms; manual DNS-01
cannot auto-renew unattended (auto-renew forced off and surfaced in the UI).
- Migration v8: additive, idempotent columns on letsencrypt_accounts/orders
and acme_challenges, plus a new letsencrypt_account_dns_credentials table.
- Challenge-type-aware diagnostics (port80/routing/DNS checks skipped for
DNS-01) and a DNS-01 event timeline in the order detail.
- Frontend: DNS-01 account + credentials management, cert wizard adaptation,
order-detail TXT records + verify, orders/renewal Method columns, and a
Settings kill-switch. README, release notes, and API docs updated.
Implements #35.
Manage highly-available virtual IPs backed by Keepalived (VRRP) directly from the OpenManager
UI — no more SSHing into nodes to install/configure Keepalived by hand. Builds on the agent
pull-architecture: define the VIP centrally, click Apply, and the agents converge.
Highlights:
- New "HA / VIP" tab: create a virtual IP, pick a per-node interface, select which pool nodes
participate (MASTER/BACKUP roles + priorities); live MASTER/BACKUP/FAULT per node.
- On Apply, agents install & configure Keepalived (unicast VRRP, cloud-safe default) across the
major distros (Debian/Ubuntu, RHEL/CentOS/Alma/Rocky, Fedora, SUSE/openSUSE, Alpine) with a
HAProxy health-check, so the VIP fails over automatically when HAProxy drops.
- Single-node (a managed floating IP without failover) and multi-node VRRP failover both work.
- VIP changes ride the standard Apply Management flow with the standard "View Change" diff.
- Approval-gated deletion (safety): deleting a running VIP is staged for approval and the VIP
keeps running, untouched, until you approve it — an agent never tears a VIP down without an
explicit human approval. Per-VIP Diagnostics view; opt-in package uninstall (only on nodes
where OpenManager installed it). A node already running a hand-managed Keepalived is detected
and never overwritten ("externally managed").
- Fully opt-in and backward compatible: nodes/clusters without a VIP are unaffected. Adds
vip_instances + vip_members tables (idempotent SCHEMA_VERSION bump; existing data and
passwords unaffected) and a `vip` RBAC permission group.
- Also includes a HAProxy config-generator robustness fix: auto-inject a stick-table when a
frontend uses a stick counter (track-sc / sc_*_rate) but declares none.
On-prem / L2 (VRRP) scope; the UI notes the cloud caveat.
