Keycloak Docker setup with PostgreSQL

A Keycloak setup for development and production.

Guide

Download and build the latest versions of the images

docker-compose build --pull --no-cache

Start Docker Compose in detached mode:

For Development

docker compose up -d

For Production

Create a .env.prod file and paste the code below :

SERVER_NAME=example.com

KEYCLOAK_ADMIN=admin
KEYCLOAK_ADMIN_PASSWORD=admin

POSTGRES_VERSION=14.5
POSTGRES_DB=keycloak
POSTGRES_USER=keycloak
POSTGRES_PASSWORD=keycloak

Be sure to replace example.com with your actual domain name and to set the values of KEYCLOAK_ADMIN, KEYCLOAK_ADMIN_PASSWORD, POSTGRES_DB, POSTGRES_USER, POSTGRES_PASSWORD to cryptographically secure random values.

Then run : docker compose -f docker-compose.yml -f docker-compose.prod.yml --env-file .env.prod up -d
