etcd (Hardened) — documentation & support card

At a glance

Type	Hardened VM image
Upstream / license	etcd (Apache-2.0) — see licenses
Version	etcd 3.x from upstream release binaries (built from source where advisories require). Current builds: release notes.
Architecture	x86-64
Sizing	Any current-generation instance with ≥ 4 vCPU (pay-as-you-go floor); 8 vCPU recommended for production.

Marketplaces

• AWS Marketplace — submission in progress (image verified 2026-07-21) (base: Amazon Linux 2023)

Network ports

Port	Purpose	State
22	SSH (key-only)	default-open
2379	Client API — 127.0.0.1	customer-must-open (config + firewall)
2380	Peer — localhost (single node)	optional

"customer-must-open" means a cloud firewall rule and, where noted, an in-image configuration change — both deliberate. Closed by default is the design.

Access & credentials

No shared or default credentials are included in this image. Access uses the SSH key you supply at launch; any application credential is generated uniquely on your instance at first boot and stored only there — we never know it.

Log in: SSH with your launch key; `etcdctl` talks to 127.0.0.1:2379 without auth (local-only posture).

This product has no application credential of its own.

Data & dependencies

• Data locations: /var/lib/etcd — all data stays on your instance and volumes.
• Does any data leave your tenant? No. Telemetry: none. Our images contain no phone-home, no usage beacons, no license servers. The only parties that know you deployed our software are you and your cloud provider's billing system.
• We have no access to your deployment. Your instance runs in your tenancy under your IAM; remote access for a support session exists only if you explicitly grant it, and you can revoke it at any time.
• External dependencies at deploy/runtime: None — the image is fully self-contained at deploy time; no internet access is required to boot and run.

Operate

• First boot: Build-time member state is wiped at capture; a fresh member initializes on your first boot.
• Update / patch: Replace with the newest image version; etcd data migrates via snapshot/restore.
• Backup / restore: etcdctl snapshot save /path/backup.db (then copy off-box); restore with etcdctl snapshot restore.
• Uninstall: delete the VM/deployment and its volumes — nothing else persists, and software billing stops with the instance under your cloud's marketplace terms.
• Logs: journalctl -u etcd -f
• Health check: etcdctl endpoint health → 127.0.0.1:2379 is healthy

Known limitations

Single member; a production quorum is 3+ nodes you architect deliberately.
