Redis-Sentinel无法连接到Docker中的主节点

问题描述

我一直在尝试为基于docker的应用设置主从标签设置。我很喜欢下面给出的docker-compose.yaml文件。但是它没有工作并且没有失败。 泊坞窗图像来自bitnami。

Docker-Compose文件：

version: '2'

networks:
  app-tier:
    driver: bridge

services:
  redis:
    image: 'bitnami/redis:latest'
    environment:
      - REdis_REPLICATION_MODE=master
      - ALLOW_EMPTY_PASSWORD=yes
    networks:
      - app-tier
    ports:
      - '6379'
  redis-slave:
    image: 'bitnami/redis:latest'
    environment:
      - REdis_REPLICATION_MODE=slave
      - REdis_MASTER_HOST=redis
      - ALLOW_EMPTY_PASSWORD=yes
    ports:
      - '6379'
    depends_on:
      - redis
    networks:
      - app-tier
  redis-sentinel:
    image: 'bitnami/redis-sentinel:latest'
    depends_on:
      - redis
      - redis-slave
    ports:
      - '26379:26379'
    networks:
      - app-tier

失败，并显示错误：
