infracamp/redis repository overview

⁠Infracamp Redis container (infracamp:redis)

This container is build upon the official redis-container. But it offers two extensions:

• It runs as non-root user by default
• It is easily configurable by environment variables (eg. in a docker stack)
• It comes with presets for
  • In Memory only usage
  • Snapshot usage
  • AOF Logfiles

⁠Presets available

See the examples below on how to use the container. The container will be rebuild daily (:testing) or weekly (:latest).

Make sure no ports are exposed to the outside world - no security configuration is available. It is considered for stack-inside use only.

⁠Configuration for all presets

Example for your stack-file to spin up a memory only redis instance with 100mb memory limit.

⁠Memory Only (Caches, etc)

• Redis Documentation about persistence⁠
• Config file preset⁠

No persistence to disk. Usage for caching / volatile data only.

services:
  redis:
    image: infracamp/redis
    environment:
      - PRESET=memory_only
      - MEMORYLIMIT=500mb

⁠RDB Snapshot Persistence (Session storage)

• Redis Documentation about persistence⁠
• Config file preset⁠

The Memory is snapshotted at specified interval to the disk. RDB is very compact and very perfomant. But you might loose between two snapshots

Example:

services:
  redis:
    image: infracamp/redis
    environment:
      - PRESET=rdb_snapshots
      - MEMORYLIMIT=500mb
      - SNAPSHOT_INTERVAL=30
    volumes:
      - redisVolume:/data

⁠Append-only file persistence (AOF)
