docker - 从主机访问 Redis Docker 容器

问题描述

我想创建 6 个 Redis Docker 容器并将它们设置为从我的 Windows 主机作为集群工作。为此，首先，我创建了一个 redis 配置文件：

port 6379
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
appendonly yes

和 Dockerfile：

FROM redis
COPY clusterconfig.conf /usr/local/redis.conf
CMD ["redis-server", "/usr/local/redis.conf"]

在此之后，创建了一个 docker-compose.yml （删除了一些行以减少行数。完整文件在这里。）

version: "3.1"
services:
  redis-master-1:
    build: ./
    networks:
      redisnet:
        ipv4_address: 10.0.0.2
    command: sh -c "redis-server /usr/local/redis.conf --port 7000 --cluster-enabled yes --cluster-config-file nodes.conf --cluster-node-timeout 5000"
  redis-master-2:
    build: ./
    networks:
      redisnet:
        ipv4_address: 10.0.0.3
    depends_on:
      - redis-master-1
    command: sh -c "redis-server /usr/local/redis.conf --port 7001 --cluster-enabled yes --cluster-config-file nodes.conf --cluster-node-timeout 5000"
  // Goes like this and created 4 more redis containers
  redis-setup:
    image: ruby
    command: sh -c "gem install redis && wget http://download.redis.io/redis-stable/src/redis-trib.rb && yes yes | ruby redis-trib.rb create --replicas 1 10.0.0.2:7000 10.0.0.3:7001 10.0.0.4:7002 10.0.0.5:7003 10.0.0.6:7004 10.0.0.7:7005 && while sleep 3600; do :; done"
    networks:
      redisnet:
        ipv4_address: 10.0.0.8
    depends_on:
      - redis-master-1
      - redis-master-2
      - redis-master-3
      - redis-slave-1
      - redis-slave-2
      - redis-slave-3
networks:
  redisnet:
    driver: bridge
    ipam:
      config:
        - subnet: 10.0.0.0/16

现在，当我执行docker-compose up命令 6 时，Redis 实例开始按预期以集群模式运行。现在如何从主机访问我的 Redis 实例？

解决方案

根据您的完整docker-compose.yaml文件（配置中的一些示例）：

services:
  redis-master-1:
    build: ./
    ports:
      - 7000:7000
    networks:
      redisnet:
        ipv4_address: 10.0.0.2
    command: sh -c "redis-server /usr/local/redis.conf --port 7000 --cluster-enabled yes --cluster-config-file nodes.conf --cluster-node-timeout 5000"

您可以通过在 上指定的端口访问任何redis容器localhost。

例如，对于上述redis-master-1容器，您需要使用localhost:7000它才能到达它等。
