Spark Cluster with Docker 🐳 This repository contains a containerized setup for deploying an Apache Spark cluster using Docker and Docker Compose. It simplifies the process of running a distributed Spark environment for local development, testing, or deployment in production.

📚 Features Pre-configured Spark Master and Worker Nodes Horizontal Scaling: Easily scale worker nodes with Docker Compose. Custom Spark Configurations: Update Spark settings via configuration files. Multi-host Deployment: Suitable for deployment on Hetzner servers or similar platforms. Monitoring Tools: Access Spark Web UI to monitor tasks and jobs. 🚀 Quick Start Guide Prerequisites Ensure you have the following installed:

Docker Docker Compose Steps to Get Started Clone the repository:

bash Copy code docker-compose build Start the Spark Cluster:

bash Copy code docker-compose up -d Access the Spark Master Web UI:

arduino Copy code http://localhost:8080 Scale the worker nodes as needed:

bash Copy code docker-compose up --scale spark-worker=3 🛠️ Configuration Modify Spark configurations in the config/ folder. Update docker-compose.yml to adjust the number of workers or ports. 📂 Repository Structure plaintext Copy code spark-cluster-docker/ ├── config/ │ ├── spark/ # Spark configuration files ├── workspace/ # Workspace for Spark jobs and scripts ├── docker-compose.yml # Docker Compose configuration file ├── Dockerfile.spark-cluster # Dockerfile for Spark cluster setup ├── entrypoint.sh # Entrypoint script for containers └── README.md # Project documentation 🌐 Access Points Service URL Default Port Spark Master UI http://localhost 8080 Spark Worker UI http://localhost 8081+ 📦 Scaling the Cluster To scale worker nodes, use Docker Compose's --scale option:
