Introduction

同盾 Redis 主从架构中的 Standby 副本镜像，从 Master 同步数据并提供只读查询，需配置主节点地址与持久化目录。

Details

tongduncloud/redis-standby 运行 Redis replica 模式，启动时 REPLICAOF 指向主 Redis 并持续 PSYNC 复制。Standby 节点可分担读流量但故障切换需外部 Sentinel 或 K8s Operator 编排。与官方 redis 镜像相比为同盾定制打包；生产应固定 tag、挂载 /data 做 RDB/AOF 持久化，并限制网络仅允许从 Master 与监控网段访问 6379。

快速启动

docker run -d --name redis-standby \
  -p 6379:6379 \
  -e REDIS_MASTER_HOST=redis-master \
  -e REDIS_MASTER_PORT=6379 \
  docker.io/tongduncloud/redis-standby:latest

推荐实践

docker run -d --name redis-standby \
  --restart unless-stopped \
  -p 6379:6379 \
  -v /data/redis-standby:/data \
  -e REDIS_MASTER_HOST=redis-master.internal \
  -e REDIS_MASTER_PORT=6379 \
  -e REDIS_PASSWORD=change-me \
  docker.io/tongduncloud/redis-standby:6.2.0

核心参数说明

  • -p 6379:6379 — Redis 复制与只读客户端端口
  • -e REDIS_MASTER_HOST — 主节点 hostname/IP
  • -e REDIS_MASTER_PORT — 主节点端口
  • -e REDIS_PASSWORD — 主从认证密码
  • -v /data/redis-standby:/data — RDB/AOF 持久化
  • --restart unless-stopped — 复制链路中断后自动重连

Master 独立 StatefulSet 或 Helm；Sentinel 或 Operator 负责 failover，StorageClass 按 IOPS 需求选型。
