Keycloak is an open-source identity and access management server (Java/Quarkus) providing single sign-on, OpenID Connect, OAuth 2.0, SAML 2.0, user federation, and social login. This Lynxroute build is hardened and ready out of the box: production mode on a bundled local PostgreSQL, a random admin password generated at first boot, an nginx TLS perimeter on port 443, Keycloak's HTTP, management and database ports bound to localhost, UFW firewall pre-configured, and a CIS Level 1 hardened Ubuntu 24.04 LTS base.

Overview
This is a repackaged software product wherein additional charges apply for hardening, security configuration, and support.
WHAT IS KEYCLOAK
Keycloak is an open-source identity and access management (IAM) server built on Java and Quarkus. It gives applications single sign-on and standards-based authentication and authorization through OpenID Connect, OAuth 2.0, and SAML 2.0, plus realm-based multi-tenancy, role-based access control, user federation against LDAP and Active Directory, identity brokering, social login, fine-grained authorization, and a full admin and account console. Applications integrate through the per-realm OIDC discovery document and standard token endpoints, so any compliant OIDC or SAML client works without vendor SDKs. Keycloak requires a production relational database; this image bundles a local PostgreSQL instance and rotates its password at first launch. Apache-2.0 license, no vendor lock-in - the same codebase as the Red Hat build of Keycloak, with no open-core feature gating.
WHAT THIS AMI ADDS
Security hardening:
- Production mode (kc.sh build, then start --optimized) against a bundled local PostgreSQL - the embedded H2 database, which upstream supports for development only, is not used
- Random admin password generated at first launch and written to /root/keycloak-credentials.txt (root-only); no password is baked into the image
- PostgreSQL password also generated per instance at first launch
- nginx TLS perimeter on port 443 (self-signed certificate; Certbot pre-installed so a CA-signed certificate is one command away)
- Keycloak HTTP (8080), management and health (9000), and PostgreSQL (5432) all bound to 127.0.0.1 only
- UFW firewall pre-configured (ports 22, 80 and 443 only; 80 redirects to HTTPS)
- fail2ban, auditd, AppArmor pre-configured
- 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
- Keycloak security baked in: production mode on a bundled local PostgreSQL, a random admin password generated at first launch and stored root-only, an nginx TLS perimeter on port 443 with Certbot pre-installed, and Keycloak's HTTP (8080), management (9000) and PostgreSQL (5432) ports all bound to 127.0.0.1. UFW pre-configured for ports 22, 80 and 443 only.
- 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.
- Standards-based single sign-on: OpenID Connect, OAuth 2.0, SAML 2.0, realms, role-based access control, user federation (LDAP/Active Directory), identity brokering, and social login for any compliant client. Apache-2.0 license - fully auditable, no vendor lock-in.

Dimensions summary
You pay by the hour for the EC2 instance size you choose to run this hardened Keycloak image. Four instance sizes are available: t3.large, m6i.large, m6i.xlarge, and m6i.2xlarge. Each represents a different compute and memory allocation, so pricing scales with the capacity you select. The larger m6i sizes give more resources for heavier workloads, while t3.large and m6i.large suit lighter needs. All sizes deliver the same hardened image; you pick based on how much compute you need. Billing runs on usage, so you only pay for the hours you run.
Top-of-mind questions for buyers
Each dimension bills per hour for one running EC2 instance of that size. t3.large is a burstable general-purpose type, while m6i.large, m6i.xlarge, and m6i.2xlarge are general-purpose types with increasing vCPU and memory. The size you launch determines your hourly software rate.
The software rate meters running instance-hours. A fully stopped instance does not accrue software charges. Stopped instances may still incur underlying AWS storage fees for attached volumes, but those are separate AWS charges, not the hourly software rate for this image.
Every size runs the same hardened Ubuntu 24.04 LTS base with CIS Level 1 benchmarks applied. Each deployed instance includes a software bill of materials, a CIS Conformance Report, unique credentials generated at first boot, firewall, and intrusion-prevention tooling. Instance size changes only compute and memory, not the bundled contents.

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 (m6i.large recommended; t3.large minimum)
- Open Security Group - allow TCP 443 and TCP 22 from your IP
- SSH: ssh -i key.pem ubuntu@<PUBLIC_IP>
- Read the generated login: sudo cat /root/keycloak-credentials.txt
- Open https://<PUBLIC_IP>/admin/ in your browser - accept the self-signed certificate warning. First launch takes about 1-2 minutes while the database schema is prepared and the JVM warms up; until Keycloak is ready the page shows a loading screen that refreshes itself.
- Sign in as "admin" with the password from step 4, then create your own administrator under the master realm and remove or change the generated bootstrap account.
- Create your first realm, register your applications as clients, and add users under that realm.
Keycloak runs in production mode (start --optimized) against a bundled local PostgreSQL - no external database is required, and the embedded H2 database (upstream supports it for development only) is not used. Keycloak's HTTP listener, its management and health port, and PostgreSQL are bound to 127.0.0.1; nginx terminates TLS on port 443 and reverse-proxies to Keycloak. The admin console, the account console, and the OIDC/OAuth2/SAML token endpoints are all served over HTTPS on port 443. Each realm publishes an OIDC discovery document under the path /realms/REALM/.well-known/openid-configuration on the same host, where REALM is the realm name (the built-in realm is named master).
The admin password and the PostgreSQL password are generated uniquely per instance at first launch and saved to /root/keycloak-credentials.txt. Restrict Security Group port 443 to your own IP until you have signed in and created your own administrator.
For production, replace the self-signed certificate and the IP-based hostname with your own domain: sudo certbot --nginx -d yourdomain.com sudo sed -i 's|^hostname=.*|hostname=https://yourdomain.com |' /opt/keycloak/conf/keycloak.conf sudo systemctl restart keycloak
