java - 如何从本地主机连接到 docker redis 集群

Question

我使用脚本创建了 redis docker 集群：

cluster_creation.sh

#------------ bootstrap the cluster nodes --------------------

start_cmd='redis-server --port 6379 --cluster-enabled yes --cluster-config-file nodes.conf --cluster-node-timeout 5000 --appendonly yes'
redis_image='redis:5.0-rc'
network_name='docker-it-network'

docker network create $network_name
echo $network_name " created"

#---------- create the cluster ------------------------

for port in `seq 6379 6384`; do \
 docker run -d --name "redis-"$port -p $port:6379 --net $network_name $redis_image $start_cmd;
 echo "created redis cluster node redis-"$port
done

cluster_hosts=''

for port in `seq 6379 6384`; do \
 hostip=`docker inspect -f '{{(index .NetworkSettings.Networks "docker-it-network").IPAddress}}' "redis-"$port`;
 echo "IP for cluster node redis-"$port "is" $hostip
 cluster_hosts="$cluster_hosts$hostip:6379 ";
done

echo "cluster hosts "$cluster_hosts
echo "creating cluster...."
echo 'yes' | docker run -i --rm --net $network_name $redis_image redis-cli --cluster create $cluster_hosts --cluster-replicas 1;

该脚本创建了集群，并且所有节点都已连接。

但是我无法通过我的 spring boot 应用程序连接到这个 redis 集群。我尝试使用 localhost:6379 , 127.0.0.1:6379, host.docker.internal:6379 但这些都不起作用。

如何在本地公开redis集群docker容器以供应用程序使用？

注意：应用程序没有在 docker 中运行。如果应用程序在 docker 中运行，我可以使用 redis 端点作为redis-6379:6379访问 redis 。但是无法使用 localhost:6379 从本地主机直接访问

错误：

gframework.data.redis.TooManyClusterRedirectionsException: No more cluster attempts left.; nested exception is redis.clients.jedis.exceptions.JedisClusterMaxAttemptsException: No more cluster attempts left.
