This is a repackaged open source software product wherein additional charges apply 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.
Overview
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 Inc.
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).
Highlights
- Production-ready: Keycloak 26.7 on Amazon Corretto 21, systemd-managed, health endpoints enabled; swap the embedded database for PostgreSQL when you scale.
- 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.

Pricing
Pricing is based on actual usage, with charges varying according to how much you consume. Subscriptions have no end date and may be canceled any time.
Additional AWS infrastructure costs may apply. Use the AWS Pricing Calculator to estimate your infrastructure costs.
Dimension | Cost/hour |
|---|---|
c7i.2xlarge Recommended | $0.92 |
c7i.4xlarge | $1.84 |
c7i.xlarge | $0.46 |
Dimensions summary
You pay by the hour for the instance size you launch. All three options run the same hardened image; they differ only by compute capacity. The c7i.xlarge gives you 4 vCPU and 8 GiB memory. The c7i.2xlarge gives you 8 vCPU and 16 GiB. The c7i.4xlarge gives you 16 vCPU and 32 GiB. Software charges scale with the size you pick. There is no subscription and no minimum. AWS infrastructure charges are billed separately by AWS. Charges stop when you terminate the instance.
Top-of-mind questions for buyers
The software charge covers image hardening, continuous patching, vulnerability scanning, and business-day support. It does not cover the underlying Keycloak software, which stays free under its open-source license. You pay for the maintained, security-hardened image and the support around it.
Software charges stop when you terminate the instance. There is no subscription and no minimum, so metering follows running time. A stopped instance may still incur AWS storage fees for its EBS volume, billed separately by AWS.
Yes. The software charge is tied to the instance size you launch. Moving from c7i.xlarge to c7i.2xlarge or c7i.4xlarge changes the hourly rate. You pick the size at launch; scaling up means launching a larger type, not an automatic upgrade.

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.
Version release notes
[Security] Refreshed image: rebuilt on the latest hardened Amazon Linux 2023 baseline; all OS packages current at build.
Additional details
Usage instructions
- Launch from AWS Marketplace (1-Click or EC2 console).
- Use a web browser to access the application at http://<public-ip>:8080. 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 access: ssh -i <key> ec2-user@<public-ip>. Root login is disabled; use sudo.
- Verify: sudo systemctl status keycloak (health endpoints are enabled).
- Sensitive data: the only credential is the temporary admin password (the EC2 instance ID), which you replace at first login. Logs under /var/log may contain client IPs - treat as personal data.
- Backup: snapshot the EBS volume (it contains all configuration and data).
- Resources: a single instance uses 1 EC2 instance and 1 gp3 EBS volume; no other AWS resources are created.
- Support: support@dcassociatesgroup.com .
