Keycloak Single Sign-On Server

Keycloak 26.8.1 in production mode with PostgreSQL 16, nginx and Webmin on Ubuntu 24.04 LTS. Add sign-in, single sign-on, user management and two-factor authentication to your web and mobile applications through OpenID Connect, OAuth 2.0 and SAML, connect LDAP or Active Directory, and secure APIs with tokens, without building login yourself. The server address and certificate follow the instance's public IP, and a domain name you set is left alone.

Getting started

From launch to signed in, step by step.

  1. Subscribe on AWS Marketplace and launch in your region with TCP 22, 80, 443 and 8000 open; wait about three minutes for first boot.

  2. Open https://<instance-public-ip>/admin/, accept the one-time self-signed certificate warning and sign in with username admin and your EC2 Instance ID, lowercase exactly as the console shows it (for example i-0123456789abcdef0). Sign-in from outside the server must use HTTPS.

  3. Applications use the same address, for example https://<instance-public-ip>/realms/<your-realm>/.well-known/openid-configuration.

  4. Webmin is on port 8000 with the same username and password. SSH as ubuntu with your key pair. Change passwords with sudo bash /home/ubuntu/iscripts/pass_keycloak.sh or pass_webmin.sh; check the server with sudo bash /home/ubuntu/iscripts/keycloak_status.sh.

  5. For production, point your own domain at the instance and replace the self-signed certificate with a trusted one.

Security posture

What this image does and does not ship with, one fact per line.

  • Clean-room build on Canonical's official Ubuntu 24.04 LTS image: every component comes from its own official source, and nothing is copied from any third-party image.

  • Keycloak is the official release tarball, run in production mode.

  • No credentials or keys ship in the image: on first boot every instance creates its own administrator, realm signing keys, database password and HTTPS certificate, and sets its own Webmin password, from EC2 instance metadata (IMDSv2).

  • Keycloak and PostgreSQL listen only on the server itself behind nginx, no cluster port is opened, and sign-in from outside requires HTTPS.

  • SSH is key-only, and build-time SSH keys, host keys, machine ID, shell history and logs were removed before imaging.

  • The bundled password tools enforce at least 10 characters with upper- and lower-case letters, a number and a symbol.

  • Replace the self-signed certificate with a trusted one before production use, and restrict ports 22 and 8000 to trusted IP ranges in your security group.
