Keycloak Deployment with PostgresSQL on Kubernetes

This repository contains Kubernetes manifests for deploying Keycloak with Postgres as database for persistance, an open-source Identity and Access Management (IAM) solution. The configuration uses an Nginx Ingress Controller to expose Keycloak to the public internet securely.

Prerequisites

  1. A Kubernetes cluster.
  2. kubectl configured to interact with your cluster.
  3. Nginx Ingress Controller installed in your cluster.
  4. Domain name (e.g., domain.com) pointing to your ingress controller's IP address.

Deployment Overview

This setup includes:

  • Deployment: Runs Keycloak in development mode (start-dev).
  • Service: Exposes Keycloak within the cluster.
  • Ingress: Provides external access to Keycloak via the configured domain.

Files

  • deployment.yaml: Defines the Keycloak Deployment, Service, and Ingress resources.

Keycloak Configuration

The Keycloak container is configured with the following environment variables:

Variable Value Description
KEYCLOAK_ADMIN admin Default admin username.
KEYCLOAK_ADMIN_PASSWORD admin Default admin password.
KC_HOSTNAME https://domain.com External hostname for Keycloak.
KC_PROXY edge Proxy setting for handling SSL termination.

Steps to Deploy

  1. Clone this repository:

    git clone https://github.com/your-username/your-repo.git
cd your-repo

  2. Apply the manifests:

    kubectl apply -f deployment.yaml

  3. Verify that all resources are created:

    kubectl get all

  4. Access Keycloak at https://domain.com. Use the admin credentials (admin/admin) to log in.
