Keycloak is a robust open-source identity and access management solution for securing web applications and services. It offers a range of authentication and authorization features, making it a valuable tool for safeguarding your resources.
In this blog, I'll guide you through the process of setting it up and then I'll provide a link where you can integrate it seamlessly with Oracle APEX.
Keycloak needs SSL, so you need a custom domain (unconfirmed: or a self-signed certificate). The easiest way to get Keycloak working on Oracle Compute
Install Nginx Proxy Manager using this guide (including the recommended Docker installation)
Create a keycloak-compose.yml file
Paste in the following
version: '3' services: keycloak: image: quay.io/keycloak/keycloak:latest ports: - "8280:8080" environment: - KEYCLOAK_ADMIN=admin - KEYCLOAK_ADMIN_PASSWORD=admin - PROXY_ADDRESS_FORWARDING=true command: - start-dev - --proxy=edge - --hostname-strict=false - --hostname-strict-https=false container_name: keycloak
Then start docker-compose
docker-compose -f keycloak-compose.yml up -d
In your Domain Administration page (I'm using Cloudflare) create a proxied A type subdomain as keycloak and point it at the Public IP address of your Compute box
Note: If you've forgotten your Public IP address. Take a look here
Visit your Nginx Proxy Manager admin page
Reminder: If you followed the guide in the first step, you might've used a dashboard subdomain
Click Proxy Hosts > Add Proxy Host
Add your domain name e.g. keycloak.snescentral.com and complete the form as per the picture below
Switch to Custom locations and complete the form as per the picture below
For the configuration, use this
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $http_host; proxy_redirect off; proxy_buffer_size 128k; proxy_buffers 4 256k; proxy_busy_buffers_size 256k;
Switch to SSL and select your SSL Certificate
Try out your subdomain name in your browser. You should see the below.
Click on Adminstration Console
Sign in with the following details
username: admin password: admin
Click Admin > Manage Account > Signing in
Click on Update and change your password
