Overview
This is a repackaged software product wherein additional charges apply for hardening, security configuration, and support.
WHAT IS TEMPORAL
Temporal is an open-source durable execution platform for orchestrating long-running, fault-tolerant application workflows. Developers write workflows and activities as ordinary code (with Go, Java, Python, TypeScript, .NET, and PHP SDKs) and the Temporal Server guarantees they run to completion despite process crashes, restarts, or infrastructure failures - persisting every step and driving automatic activity retries, durable timers, signals, queries, schedules, and child workflows. The server is written in Go and runs four services (frontend, history, matching, worker); a separate Web UI provides workflow visibility, search, and history inspection. This image bundles a local PostgreSQL for event history and advanced (searchable) visibility, so the whole platform runs on one instance with no external dependencies. MIT license - a self-hosted durable workflow engine with no per-action fees and no vendor lock-in.
WHAT THIS AMI ADDS
Security hardening:
- Unique Web UI admin password and PostgreSQL password generated per instance at first boot
- Web UI gated by an nginx TLS reverse proxy with HTTP Basic Auth; TLS terminated on 443
- gRPC frontend (port 7233) bound to 127.0.0.1 only - never exposed; attach VPC workers explicitly
- Bundled PostgreSQL bound to 127.0.0.1 only
- UFW firewall - ports 22 (SSH) and 443 (HTTPS) only
- fail2ban, AppArmor
- CVE scan - every image is scanned for vulnerabilities before release
OS hardening (CIS Level 1):
- CIS Ubuntu 24.04 LTS Level 1 benchmark applied via ansible-lockdown
- auditd, SSH hardening, Kernel hardening, IMDSv2 enforced
Compliance artifacts:
- SBOM - CycloneDX 1.6 at /etc/lynxroute/sbom.json
- CIS Conformance Report at /etc/lynxroute/cis-report.html
- CIS Tailored Profile at /usr/share/doc/lynxroute/CIS_TAILORED_PROFILE.md
Highlights
- Temporal security baked in: a unique Web UI password and PostgreSQL password generated at first boot, the Web UI behind an nginx TLS reverse proxy with HTTP Basic Auth, and the gRPC frontend plus the bundled PostgreSQL bound to loopback only behind a UFW firewall that opens just SSH and HTTPS.
- CIS Level 1 hardened Ubuntu 24.04 LTS: auditd, fail2ban, AppArmor, SSH key-only, IMDSv2 enforced. CVE-scanned before every release. SBOM (CycloneDX) and CIS Conformance Report included.
- Durable execution for application workflows: fault-tolerant workflows and activities as code, automatic retries, durable timers, signals, schedules, and full event history with a visibility Web UI, backed by PostgreSQL. MIT license - fully auditable, no vendor lock-in.

64-bit (x86) Amazon Machine Image (AMI)
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.

Additional details
Usage instructions
- Launch instance (t3.large recommended; t3.medium minimum)
- Open Security Group - allow TCP 443 from your IP
- SSH: ssh -i key.pem ubuntu@<PUBLIC_IP>
- Read credentials: sudo cat /root/temporal-credentials.txt
- Open https://<PUBLIC_IP>/ in your browser - accept the self-signed certificate warning
- Log in to the Temporal Web UI with the admin username and password from the credentials file (HTTP Basic Auth)
The default namespace is registered at first boot, and the bundled temporal CLI is on PATH (for example: temporal workflow list --namespace default). The Web UI runs on 127.0.0.1:8080 and the gRPC frontend on 127.0.0.1:7233; nginx is the TLS and Basic Auth perimeter on 443. To connect workers from elsewhere in your VPC, follow the steps in the credentials file and open TCP 7233 to your VPC CIDR only - never to 0.0.0.0/0. Credentials are saved to /root/temporal-credentials.txt at first boot. Replace the self-signed TLS certificate with a CA-signed certificate (certbot is pre-installed) for production use.
