Keycloak (Hardened) on Amazon Linux 2023
This product has charges associated with it for image hardening, maintenance, and support. Keycloak identity and access management on Amazon Linux 2023 with Amazon Corretto 21, security-hardened for production: minimal package set, SSH key-only access, IMDSv2-only, no default admin password (per-instance bootstrap credential), and continuously patched images.
Why this image
- Security-hardened at build time: minimal packages, key-only SSH, IMDSv2-only, no default admin password - bootstrap credential is per-instance (the EC2 instance ID).
- Continuously patched: rebuilt, vulnerability-scanned, and republished on a regular cadence.
- Production-ready: Keycloak 26.7 on Amazon Corretto 21, systemd-managed, health endpoints enabled; swap the embedded database for PostgreSQL when you scale.
About
Keycloak (Hardened) on Amazon Linux 2023 is a production-ready, security-hardened image of the Keycloak identity and access management server (OpenID Connect, OAuth 2.0, SAML 2.0), maintained and supported by Derek Coleman & Associates Incorporated.
This is repackaged open-source software. Keycloak is a Cloud Native Computing Foundation project distributed under the Apache License 2.0. Keycloak is a trademark of Red Hat, Inc.; this listing is not endorsed by or affiliated with Red Hat or the CNCF. This product bundles unmodified upstream Keycloak on a hardened Amazon Linux 2023 base; the charges associated with this listing are for image hardening, continuous patching, vulnerability scanning, and business-day support - not for the underlying open-source software, which remains free.
Hardening baseline: minimal package footprint, SSH key-only access (password authentication disabled), IMDSv2 enforced, and no default admin credentials - the temporary bootstrap admin password is generated per instance on first boot (set to the EC2 instance ID); Keycloak requires you to create a permanent admin account on first login. Images are rebuilt, scanned for HIGH and CRITICAL vulnerabilities, and republished on a regular cadence so that new launches start current. Ships with the embedded dev-file database for evaluation and small deployments; point it at PostgreSQL for production clusters (documented in the usage instructions).
Pricing (hourly usage, AWS Marketplace)
| Instance type | Size | Software price |
|---|---|---|
| c7i.xlarge | 4 vCPU / 8 GiB | $0.46/hr |
| c7i.2xlarge | 8 vCPU / 16 GiB | $0.92/hr |
| c7i.4xlarge | 16 vCPU / 32 GiB | $1.84/hr |
Recommended: c7i.2xlarge. AWS infrastructure charges are separate and billed by AWS. Charges stop when instances are terminated. No subscription, no minimum.
Getting started
Launch from AWS Marketplace (1-Click or EC2 console). Browse to http://<public-ip>:8080 and sign in with username admin and the temporary password equal to the EC2 instance ID (e.g. i-0abc123...); Keycloak then requires you to create a permanent admin account. For production, terminate TLS on 8443 or a load balancer, set a hostname, and configure an external PostgreSQL database in /opt/keycloak/conf/keycloak.conf, then: sudo systemctl restart keycloak. SSH: ssh -i <key> ec2-user@<public-ip>; root login is disabled; use sudo.
