The Redis image packages the Redis server binary and its runtime dependencies, default configuration files, the command‑line client (redis-cli), and optional modules. It exposes ports and mounts for persistence (RDB/AOF), supports cluster and sentinel setups, and is intended to run as a single-instance container under an orchestrator with resource limits, liveness/readiness probes, and persistent volumes for durability.
Typical workloads include low‑latency caching, session stores, pub/sub, streams, real‑time counters and leaderboards, and lightweight message queues. Teams evaluating a Redis hardened image do so to reduce attack surface and meet regulatory controls — for example, enforcing non‑root operation, up‑to‑date OS libraries, TLS, disabled or renamed risky commands, strict file permissions, reproducible builds, and image signing to support compliance and operational security requirements.
The Minimus Redis image differs from typical Redis container images by being built from scratch with only the essential runtime components and dependencies included. By excluding shells, package managers, and extraneous libraries, the Minimus Redis image significantly reduces the available attack surface, boots faster, consumes fewer resources, and is simpler to audit and maintain over time.
The Minimus hardened Redis image applies additional operational and configuration hardening—configured to run with least privilege, immutable filesystem options, and a reduced set of enabled modules—aligned with industry guidance such as NIST SP 800-190 and CIS Benchmarks. These deliberate minimization and hardening choices make the image easier to integrate into secure CI/CD pipelines and production runtimes where predictable, auditable behavior is required.
A Redis image is a container image that packages the Redis server, its runtime, and configuration so it can run in a container. It typically includes the Redis binary, required libraries, and an entrypoint that starts the server when the container starts. You pull it from a registry (like Docker Hub) and run it with a container runtime such as Docker or Podman.
In production, consider a hardened Redis image, which minimizes attack surface (small base image, non-root user, up-to-date patches) and adds security best practices to reduce risk while running Redis in containers.
Yes. The image for Redis is free to use. It is open-source software published on Docker Hub under a permissive license, so you can pull and run it locally or on your own infrastructure without license charges from the maintainers. You may incur hosting or cloud costs based on where you deploy and how many instances you run.
For security-focused deployments, a hardened Redis image is available from trusted sources. Always verify provenance, use least-privilege container configurations, and apply regular updates. If you plan to run Redis in production, review security best practices and consider official images or enterprise options.
docker pull redis:latest
docker run -d --name my-redis -p 6379:6379 redis:latestTo pull a Redis container image from Docker Hub, use Docker's pull command with a tag that matches your needs.
Examples:
docker pull redis:latestdocker pull redis:7-alpineAfter pulling, start a container as usual:
docker run -d --name my-redis -p 6379:6379 redis:latestFor security, consider a hardened Redis image from a trusted source and pin to a specific tag.
