Multi-tenant AI Platforms with Keycloak LDAP as Identity Provider
PythonTo set up a multi-tenant AI platform with Keycloak LDAP as the Identity Provider (IdP), we'll need to deploy Keycloak, configure it to use LDAP for user federation, and set up our AI services to authenticate against Keycloak. Pulumi doesn’t directly manage software configurations like Keycloak LDAP settings, but it's an excellent tool for deploying the required infrastructure, like virtual machines, container services, or serverless functions, depending on where and how you want to run your AI platform and Keycloak server.
Here’s a general outline of the steps we’ll take in a Pulumi Python program:
- Define a cloud infrastructure for a virtual machine or container service to host Keycloak.
- Deploy the virtual machine or container with the necessary image to run Keycloak.
- Set up network configurations like load balancing and firewalls to ensure secure access to Keycloak.
- Although Pulumi won’t configure Keycloak, I'll point out where you would manually set up LDAP integration after your Keycloak server is running.
Below is a Pulumi Python program that sets up the necessary cloud infrastructure for Keycloak on AWS. You would need to manually configure Keycloak with LDAP after the infrastructure is deployed.
import pulumi import pulumi_aws as aws # Step 1: Create a security group to allow inbound traffic on standard HTTP and HTTPS ports. security_group = aws.ec2.SecurityGroup('KeycloakSecurityGroup', description='Allow HTTP and HTTPS inbound traffic', ingress=[ {'protocol': 'tcp', 'from_port': 80, 'to_port': 80, 'cidr_blocks': ['0.0.0.0/0']}, {'protocol': 'tcp', 'from_port': 443, 'to_port': 443, 'cidr_blocks': ['0.0.0.0/0']} ] ) # Step 2: Create an EC2 instance to host the Keycloak server. ami_id = aws.ec2.get_ami(most_recent=True, owners=['amazon'], filters=[{ 'name': 'name', 'values': ['amzn2-ami-hvm-*-x86_64-gp2'] }]) instance = aws.ec2.Instance('KeycloakInstance', instance_type='t2.medium', # Choose the instance type according to your needs. security_groups=[security_group.name], ami=ami_id.id, tags={ 'Name': 'Keycloak-Instance' } ) # Step 3: Output the public IP to access the Keycloak Instance. pulumi.export('keycloak_public_ip', instance.public_ip) # Note that after the infrastructure is provisioned, you would need to: # - Access the newly created EC2 instance, install and configure Keycloak manually. # - Configure Keycloak to connect with your LDAP server. # - Ensure all AI services use this Keycloak server for authentication.
This program sets up the basic infrastructure to run your Keycloak server in the cloud. After deploying this Pulumi program, you'll log in to the EC2 instance, install Keycloak, and refer to Keycloak's documentation to connect with your LDAP server as an identity provider.
To complete the setup, you will configure each tenant of your AI platform to authenticate via the Keycloak server. These details are specific to the software platforms you choose to deploy for your AI applications and are configured within those applications, typically by pointing them to the Keycloak server's URL and configuring client IDs, secrets, and scopes accordingly.
