Keycloak with Let's Encrypt Using Docker Compose

📙 The complete installation guide is available on my website.

❗ Change variables in the .env to meet your requirements.

💡 Note that the .env file should be in the same directory as keycloak-traefik-letsencrypt-docker-compose.yml.

Create networks for your services before deploying the configuration using the commands:

docker network create traefik-network

docker network create keycloak-network

Deploy Keycloak using Docker Compose:

docker compose -f keycloak-traefik-letsencrypt-docker-compose.yml -p keycloak up -d

Backups

The backups container in the configuration is responsible for the following:

1. Database Backup: Creates compressed backups of the PostgreSQL database using pg_dump. Customizable backup path, filename pattern, and schedule through variables like POSTGRES_BACKUPS_PATH, POSTGRES_BACKUP_NAME, and BACKUP_INTERVAL.

2. Backup Pruning: Periodically removes backups exceeding a specified age to manage storage. Customizable pruning schedule and age threshold with POSTGRES_BACKUP_PRUNE_DAYS and DATA_BACKUP_PRUNE_DAYS.

By utilizing this container, consistent and automated backups of the essential components of your instance are ensured. Moreover, efficient management of backup storage and tailored backup routines can be achieved through easy and flexible configuration using environment variables.

keycloak-restore-database.sh Description

This script facilitates the restoration of a database backup:

1. Identify Containers: It first identifies the service and backups containers by name, finding the appropriate container IDs.

2. List Backups: Displays all available database backups located at the specified backup path.

3. Select Backup: Prompts the user to copy and paste the desired backup name from the list to restore the database.

4. Stop Service: Temporarily stops the service to ensure data consistency during restoration.

5. Restore Database: Executes a sequence of commands to drop the current database, create a new one, and restore it from the selected compressed backup file.

6. Start Service: Restarts the service after the restoration is completed.

To make the keycloak-restore-database.shh script executable, run the following command:

chmod +x keycloak-restore-database.sh

Usage of this script ensures a controlled and guided process to restore the database from an existing backup.
