cleanstart/memcached repository overview

CleanStart Container for Memcached

Enterprise-grade Memcached distributed memory caching system container optimized for high-performance caching scenarios. This container includes the latest stable Memcached server with security hardening and enterprise features. Memcached is an in-memory key-value store for small chunks of arbitrary data from results of database calls, API calls, or page rendering. The container is configured for optimal performance in distributed systems with support for multiple protocols and authentication mechanisms.

📌 CleanStart Foundation: Security-hardened, minimal base OS designed for enterprise containerized environments.

Key Features

• High-performance distributed memory caching
• Multi-threaded architecture for concurrent connections
• Support for multiple protocols (ASCII and binary)
• Enterprise-grade security features and access controls

Common Use Cases

• Database query result caching
• Session storage for web applications
• API response caching
• Distributed caching layer in microservices architecture

Quick Start

Pull Latest Image Download the container image from the registry

docker pull cleanstart/memcached:latest
docker pull cleanstart/memcached:latest-dev

Basic Run Run the container with basic configuration

docker run -d --name memcached-instance -p 11211:11211 cleanstart/memcached:latest

Production Deployment Deploy with production security settings

docker run -d --name memcached-prod \
  --read-only \
  --security-opt=no-new-privileges \
  --user 1000:1000 \
  -p 11211:11211 \
  -m 1024m \
  cleanstart/memcached:latest

Volume Mount Mount local directory for persistent data

docker run -d -v $(pwd)/memcached-data:/data cleanstart/memcached:latest

Port Forwarding Run with custom port mappings

Security & Best Practices

Recommended Security Context

securityContext:
  runAsNonRoot: true
  runAsUser: 1000
  runAsGroup: 1000
  readOnlyRootFilesystem: true
  allowPrivilegeEscalation: false
  capabilities:
    drop: ['ALL']

Best Practices

• Use specific image tags for production (avoid latest)
• Configure resource limits: memory and CPU constraints
• Enable read-only root filesystem when possible
• Run containers with non-root user (--user 1000:1000)
• Use --security-opt=no-new-privileges flag
• Regularly update container images for security patches
• Implement proper network segmentation
• Monitor container metrics for anomalies
