⁠Python Log Generator for Elasticsearch (by OpenThreat)

A lightweight Python-based log generator designed to simulate real-world application logs and send them to Elasticsearch. Ideal for testing log pipelines, Kubernetes monitoring setups, and security analysis.

⁠Features

✅ Generates realistic JSON logs similar to a Python microservice
✅ Simulates multiple services (auth-service, payment-service, etc.)
✅ Sends logs directly to Elasticsearch
✅ Supports random log levels (INFO, ERROR, DEBUG, etc.)
✅ Includes user IDs, trace IDs, and hostnames for observability
✅ Runs efficiently in Kubernetes

⁠Use Cases

🔹 Kubernetes logging testing – Simulate application logs in EFK/ELK stacks
🔹 Security monitoring validation – Generate structured logs for SIEM tools
🔹 Incident response training – Use fake logs to test forensic analysis
🔹 Performance testing – Benchmark log ingestion at scale

⁠🚀 Quick Start

1️⃣ Pull the image from Docker Hub

docker pull razvan1/elasticsearch-log-generator:latest

2️⃣ Run the container (with default Elasticsearch target)

docker run -e ELASTICSEARCH_HOST="http://my-es-server:9200" -e ELASTICSEARCH_INDEX="custom-logs" razvan1/elasticsearch-log-generator:latest

3️⃣ Deploy in Kubernetes
