Overview
Kea is a modern, high-performance open-source DHCPv4 and DHCPv6 server maintained by ISC, with a clean JSON configuration, a full management API, and pluggable back ends. Stork is its companion web dashboard: it monitors one or more Kea servers and surfaces daemons, subnets, shared networks, address pools, host reservations, and lease utilisation from a single screen. This AMI delivers Kea, Stork, the Stork agent, and their PostgreSQL back end installed, wired together, and secured - so an observable DHCP service is operational within minutes of launch.
Why This AMI
Standing up Kea with Stork by hand means installing pinned ISC packages from two repositories, configuring PostgreSQL, wiring the Kea control channel, seeding the Stork schema, rotating the default admin password, registering the Stork agent, and terminating TLS in front of the dashboard. This image completes every one of those steps at build time. It generates unique per-instance secrets on first boot and ships with a dedicated resizable data volume for the monitoring database.
Security Hardening
- No default credentials: Stork's default admin/admin login is rotated to a unique password generated on first boot, before the TLS port is reachable
- Per-instance secrets: Stork admin password, PostgreSQL role password, Kea control API credential, and self-signed TLS certificate are all generated per instance and written only to a root-only file
- Network isolation: Stork server, PostgreSQL, and the Kea control socket bind exclusively to loopback; only the nginx TLS reverse proxy is exposed
- Encrypted front door: nginx terminates TLS on port 443 with a per-instance self-signed certificate; port 80 redirects to HTTPS
- Safe-by-default DHCP: Kea serves no network interface out of the box, so the appliance cannot act as a rogue DHCP server on your VPC
- Dedicated data volume: the PostgreSQL cluster lives on its own EBS disk, surviving OS-disk changes and resizable independently
Concrete Use Cases
- ISP or campus network DHCP: manage tens of thousands of leases across multiple subnets with a high-performance DHCPv4/DHCPv6 server and monitor pool utilisation in real time through the Stork dashboard
- Multi-site enterprise: centrally monitor subnet allocation, shared networks, and lease exhaustion across distributed Kea servers from a single Stork instance
- Hospital or university network administration: maintain static host reservations for medical devices or lab equipment with full audit visibility through the browser UI
AWS Integration
Deploy on any EC2 instance type; the recommended size is m5.large. Terminate TLS at an Application Load Balancer with your own certificate, or keep the per-instance self-signed certificate. Back up the Stork monitoring database using EBS snapshots or AWS Backup, and resize the dedicated data volume independently as the estate of monitored Kea servers grows.
Quick-Start Deployment
- Launch the AMI on m5.large (or larger) with a security group allowing TCP 443 inbound for the dashboard and, if you bind Kea to serve your network, UDP 67-68 for DHCP clients
- Wait approximately 2 minutes for first-boot secret generation to complete
- SSH into the instance and retrieve the generated admin credentials from the root-only secrets file
- Browse to https:// and log in to the Stork dashboard
- Bind Kea to your target network interface and configure your subnets via the JSON config or API
Kea Open-Source Ecosystem
Kea is developed by ISC and widely adopted by ISPs, enterprises, and universities worldwide. The open-source community actively contributes to its development, and Stork provides the graphical management layer that makes Kea accessible to operations teams who prefer browser-based administration over CLI configuration.
cloudimg Support
24/7 technical support by email and chat. Help with deployment, binding Kea to your own network interfaces and subnets, adding further Kea servers to the Stork dashboard, reverse-proxy termination with your own domain and certificate, and backup planning for the monitoring database.
Highlights
- Operational in minutes with zero manual configuration: launch the AMI and reach a fully functional DHCP service with a web dashboard over TLS without installing packages, seeding databases, or editing config files. This image completes every build, wiring, and hardening step at image creation time, eliminating the manual setup a hand-built deployment requires.
- Secure by default with unique per-instance secrets: every instance generates its own Stork admin password, PostgreSQL credential, Kea control API key, and self-signed TLS certificate on first boot. The Stork server, PostgreSQL, and Kea control socket bind exclusively to loopback - only the nginx TLS reverse proxy is network-exposed. No default or shared credentials ever leave the build pipeline.
- Enterprise DHCP visibility with dedicated storage and 24/7 support: monitor DHCPv4 and DHCPv6 servers, subnets, address pools, lease utilisation, and host reservations through the Stork browser dashboard. The monitoring database lives on a dedicated EBS volume that is resizable independently of the OS disk. Backed by 24/7 cloudimg technical support via email and live chat for deployment, configuration, and ongoing operations.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
Version release notes
Initial release of Kea DHCP with the Stork web dashboard as a ready-to-use appliance: ISC Kea 3.0.3 DHCPv4 and the Stork 2.4.1 monitoring server and agent with a bundled PostgreSQL 16 back end, fronted by an nginx TLS reverse proxy, secured with a rotated Stork admin password and unique per-instance PostgreSQL, Kea control and TLS secrets generated on each instance's first boot, the local Kea pre-registered and monitored, and a dedicated data volume for the monitoring database.
Additional details
Usage instructions
Connect via SSH on port 22 as the default login user for your operating system variant (for the Ubuntu 24.04 variant the user is ubuntu). Read the per-instance Stork admin password with: sudo cat /root/kea-dhcp-stork-credentials.txt. Open the Stork web UI in a browser at https://<instance-public-ip>/ (the instance uses a per-instance self-signed TLS certificate, so accept the browser certificate warning, or front it with your own domain and certificate); plain HTTP on port 80 redirects to HTTPS. Sign in with the admin username and the STORK_ADMIN_PASSWORD from that file. The local Kea DHCPv4 server is already registered and authorised under Machines, with a demo subnet (192.0.2.0/24) so the dashboard renders real content. To serve your own network, edit the interfaces-config and subnet4 sections of /etc/kea/kea-dhcp4.conf and run: sudo systemctl restart isc-kea-dhcp4-server. The Stork server, PostgreSQL and the Kea control socket bind to loopback only; only the nginx TLS reverse proxy on port 443 is public. The PostgreSQL cluster lives on the dedicated data volume at /var/lib/postgresql. The instance security group opens ports 22, 80 and 443. The services run under systemd: systemctl status postgresql isc-kea-dhcp4-server isc-stork-server isc-stork-agent nginx.
