in redis master-slave-sentinel configuration and Spring boot application, RedisConnectionException occured - spring-boot

Question

I configured redis master-slave-sentinel environment using docker-compose.
and I completed it and tested it.
but, in my spring boot application, I wrote a redis sentinel config code.
below spring config class.
#Configuration
#EnableRedisRepositories
public class RedisConfig {
#Bean
public RedisConnectionFactory redisConnectionFactory(){
RedisSentinelConfiguration redisSentinelConfiguration = new RedisSentinelConfiguration()
.master("redis-master")
.sentinel("localhost",26379)
.sentinel("localhost",26380)
.sentinel("localhost",26381);
LettuceConnectionFactory lettuceConnectionFactory = new LettuceConnectionFactory(redisSentinelConfiguration);
return lettuceConnectionFactory;
}
}
and then I did run application, then problem occured.
enter image description here
I think there are some docker-compose network configs....
I want to know why it was...
If you guys know, .. please let me know about it.
↓ redis master-slave-sentinel config docker-compose.yml code.
