I created redis docker cluster using the script:
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_nameecho $network_name " created"#---------- create the cluster ------------------------for port in `seq 6379 6384`; do \ docker run -d --name "redis-"$port -p $port:6379 --net $network_name $redis_image $start_cmd; echo "created redis cluster node redis-"$portdonecluster_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$hostip:6379 ";doneecho "cluster hosts "$cluster_hostsecho "creating cluster...."echo 'yes' | docker run -i --rm --net $network_name $redis_image redis-cli --cluster create $cluster_hosts --cluster-replicas 1;this script created the cluster and all the nodes are connected.
However i am not able to connect to this redis cluster through my spring boot application.I tried using localhost:6379 , 127.0.0.1:6379, host.docker.internal:6379 but none of this worked.
How do I expose the redis cluster docker container to be consumed by the application in local?
Note: application isn't running in docker. If application is running in docker, I can access redis with redis endpoint as redis-6379:6379. However can't access directly from the local host machine using localhost:6379
