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.

    Azure launch steps
AWS

Getting started on Amazon Web Services

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 AWS 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.

Azure

Getting started on Microsoft Azure

From launch to signed in, step by step.

  1. Create the VM from the Azure Marketplace listing with TCP 22, 80, 443 and 8000 open in your network security group. Choose ubuntu as the administrator username so SSH and the script paths match, and wait a few minutes for first boot to finish.

  2. Open https://<vm-public-ip>/admin/ (the first certificate is self-signed, so your browser shows a warning) and sign in as admin. The password is your VM ID (Azure portal > the virtual machine > Properties > VM ID, for example 02aab8a4-74ef-476e-8182-f6d2ba4166a6). Webmin (port 8000, user admin) uses the same password. Change it with sudo bash ~/iscripts/pass_keycloak.sh, then add your domain and a trusted certificate.

  3. For production, limit admin ports to your own IP address.

Security posture

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

  • Clean-room build on Canonical's official Ubuntu 24.04 LTS image from the Azure Marketplace: every component comes from its own official source and no third-party image was launched or copied.

  • No two VMs share a login: first boot sets every password and secret key from the new VM's own vmId (read from Azure IMDS) or from fresh random values, and creates new SSH host keys.

  • The ubuntu login account ships password-locked with an empty authorized_keys, and Azure installs your own SSH key at deploy time.

  • Shell history, logs and cloud-init state are cleared before capture, and the image carries every Ubuntu 24.04 LTS security update with nothing pending.

  • Each gallery version is deployed as a Trusted Launch VM and checked against Microsoft's documented Linux certification test cases, the product's own end-to-end login tests and a stop/start cycle before it is published.

  • Restrict port 22 and the admin consoles to trusted IP ranges, and put public web consoles behind HTTPS with your own certificate.
