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.

Quick Start

Pull Latest Image

Download the container image from the registry:

docker pull ghcr.io/cleanstart-containers/memcached:latest
docker pull ghcr.io/cleanstart-containers/memcached:latest-dev

Basic Run

Run the container with basic configuration:

docker run -d --name memcached-instance -p 11211:11211 ghcr.io/cleanstart-containers/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 \
  ghcr.io/cleanstart-containers/memcached:latest

Volume Mount

Mount local directory for persistent data:

docker run -d -v $(pwd)/memcached-data:/data ghcr.io/cleanstart-containers/memcached:latest

Port Forwarding

Run with custom port mappings:

docker run -d -p 11222:11211 ghcr.io/cleanstart-containers/memcached:latest

Environment Variables

Variable	Default	Description
PATH	/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin	System PATH configuration

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
