生菜無法連接到 docker redis

[英]lettuce can't connect to docker redis

問題描述

我使用 docker-compose 創建了一個 redis 集群，當我嘗試使用 java 應用程序從我的本地計算機連接該集群時，docker 也位於該應用程序中，但是當 jedis 連接到集群時生菜超時。 Lettuce 連接到主服務器 7001 7002 7003 之后它發現其他節點並再次嘗試連接它們並超時。 這是我的代碼。

Docker-compose.yml

version: '3.8'

networks:
  redis-net:
    name: redis-net
    driver: bridge
    ipam:
      driver: default
      config:

services:

  redis-cluster:

    image: redis-cluster-node
    container_name: redis-2
    networks:
      redis-net:
        ipv4_address: 10.0.0.12

      - redis-2
      ...
    networks:

測試 class

public static void lettuce() {
        RedisURI node1 = RedisURI.Builder.redis("localhost",7001).build();
        RedisURI node2 = RedisURI.Builder.redis("localhost",7002).build();
        RedisURI node3 = RedisURI.Builder.redis("localhost",7003).build();

        RedisClusterClient redisClient = RedisClusterClient.create(Arrays.asList(node1, node2, node3));
        ClusterTopologyRefreshOptions topologyRefreshOptions = ClusterTopologyRefreshOptions.builder().dynamicRefreshSources(false).build();

        redisClient.setOptions(ClusterClientOptions.builder()
                .topologyRefreshOptions(topologyRefreshOptions)
                .build());
        StatefulRedisClusterConnection<String, String> connection = redisClient.connect();
        RedisAdvancedClusterCommands<String, String> syncCommands = connection.sync();
        syncCommands.set("test key", "test value");
}

我在這里找到了 bitnami-redis 的解決方案是我的 docker-compose.yml

services:
  redis-0:
    image: bitnami/redis-cluster
    container_name: redis-0
    restart: always
    networks:
      redis-net:
        ipv4_address: 172.22.0.100
    environment:
      - 'REDIS_PORT_NUMBER=7000'
      - 'ALLOW_EMPTY_PASSWORD=yes'
      - 'REDIS_NODES=redis-0 redis-1 redis-2 redis-3 redis-4 redis-5'
      - 'REDIS_CLUSTER_ANNOUNCE_PORT=7000'
      - 'REDIS_CLUSTER_ANNOUNCE_IP=192.168.0.13' --local ip--
      - 'REDIS_CLUSTER_BUS_ANNOUNCE_PORT=17000'
      - 'REDIS_CLUSTER_DYNAMIC_IPS=no'
    ports:
      - "7000:7000"
      - "17000:17000"

  redis-1:
    image: bitnami/redis-cluster
    container_name: redis-1
    restart: always
    networks:
      redis-net:
        ipv4_address: 172.22.0.101
    environment:
      - 'REDIS_PORT_NUMBER=7001'
      - 'ALLOW_EMPTY_PASSWORD=yes'
      - 'REDIS_NODES=redis-0 redis-1 redis-2 redis-3 redis-4 redis-5'
      - 'REDIS_CLUSTER_ANNOUNCE_PORT=7001'
      - 'REDIS_CLUSTER_ANNOUNCE_IP=192.168.0.13' --local ip--

    ports:
      - "7001:7001"
      - "17001:17001"

  redis-2:
    image: bitnami/redis-cluster
    container_name: redis-2
    restart: always
    networks:
      redis-net:
        ipv4_address: 172.22.0.102
    environment:
      - 'REDIS_PORT_NUMBER=7002'
      - 'ALLOW_EMPTY_PASSWORD=yes'

    ports:
      - "7002:7002"
      - "17002:17002"

  --- other nodes

  redis-cluster-init:
    image: redis:6.2
    container_name: redis-cluster-init
    restart: 'no'
    networks:
      redis-net:
        ipv4_address: 172.22.0.106
    depends_on:
      - redis-0
      - redis-1
      - redis-2
      - redis-3
      - redis-4
      - redis-5
    entrypoint: []
    command:
      - /bin/bash
      - -c
      - redis-cli --cluster create 172.22.0.100:7000 172.22.0.101:7001 172.22.0.102:7002 172.22.0.103:7003 172.22.0.104:7004 172.22.0.105:7005 --cluster-replicas 1 --cluster-yes

  redis_commander:
    image: rediscommander/redis-commander:latest
    container_name: redis_web
    environment:
      REDIS_HOSTS: "local:redis-0:7000,local:redis-1:7001,local:redis-2:7002,local:redis-3:7003,local:redis-4:7004,local:redis-5:7005"
    ports:
      - "5000:8081"
    depends_on:
      - redis-1
      - redis-2
      - redis-3
      - redis-4
      - redis-5
      - redis-0
      - redis-cluster-init
    networks:
      redis-net:
        ipv4_address: 172.22.0.107
networks:
  redis-net:
    name: redis-net
    driver: bridge
    ipam:
      config:
        - subnet: 172.22.0.0/16

這是我的生菜代碼

RedisURI redis0 = RedisURI.create("127.0.0.1",7000);
RedisURI redis1 = RedisURI.create("127.0.0.1",7001);
RedisURI redis2 = RedisURI.create("127.0.0.1",7002);

RedisClusterClient clusterClient = RedisClusterClient.create(Arrays.asList(redis1,redis2,redis0));

StatefulRedisClusterConnection<String, String> connection = clusterClient.connect();

RedisAdvancedClusterCommands<String, String> syncCommands = connection.sync();
