Springboot docker-compose redis Cannot get Jedis connection; - spring-boot

Question

This may seems as duplicate of docker-compose with springboot and redis and docker-compose redis connection issue but the solutions proposed there are not working in my case.
I am using springboot and the other services are unable to connect to redis service.
Below is my docker compose file:
version: "3.7"
services:
...
users:
build: ./users
ports:
- "8081:8081"
networks:
- jiji-microservices-network
depends_on:
- registry
- gateway
- redis_cache
- postgresDB
- rabbitmq
links:
- redis_cache
- postgresDB
- rabbitmq
environment:
# SPRING_CACHE_TYPE: redis
# SPRING_REDIS_HOST: redis_cache
# SPRING_REDIS_PORT: 6379
# SPRING_REDIS_PASSWORD:
SPRING_DATASOURCE_URL: jdbc:postgresql://postgresDB:5432/jiji_users
SPRING_DATASOURCE_USERNAME: postgres
SPRING_DATASOURCE_PASSWORD: postgres
SPRING_JPA_HIBERNATE_DDL_AUTO: update
EUREKA_CLIENT_SERVICEURL_DEFAULTZONE: http://registry:8090/eureka
postgresDB:
image: postgres
restart: unless-stopped
ports:
- "5432:5432"
networks:
- jiji-microservices-network
environment:
POSTGRES_PASSWORD: postgres
POSTGRES_USER: postgres
POSTGRES_DB: jiji_users
redis_cache:
image: redis:latest
restart: on-failure
command: ["redis-server","--bind","redis_cache","--port","6379"]
ports:
- "6379:6379"
networks:
- jiji-microservices-network
rabbitmq:
image: rabbitmq:management
ports:
- "5672:5672"
- "15672:15672"
networks:
- jiji-microservices-network
networks:
jiji-microservices-network:
driver: bridge
Here below is my application.yml file:
...
cache:
type: redis
redis:
host: redis_cache
port: 6379
# cache-null-values: true
time-to-live: 2592000 #30 days
...
The error message I am getting:
users_1 | 2022-03-28 02:53:40.417 INFO 1 --- [nio-8081-exec-4] c.o.u.s.CustomAuthorizationFilter : /api/v1/users/getCode
users_1 | Cannot get Jedis connection; nested exception is redis.clients.jedis.exceptions.JedisConnectionException: Could not get a resource from the pool
docker ps shows that all the containers are up and running and that redis is listening on port 6379.
PS: It works fine without docker.

The issue was related to my Redisconfiguration. Fixed bit adding redis host and redis port to JedisConnectionFactory Bean.
#Configuration
#Slf4j
public class RedisConfiguration {
#Value("${spring.redis.host}")
private String REDIS_HOST;
#Value("${spring.redis.port}")
private Integer REDIS_PORT;
#Bean
public JedisConnectionFactory jedisConnectionFactory() {
RedisStandaloneConfiguration config = new RedisStandaloneConfiguration(REDIS_HOST, REDIS_PORT);
return new JedisConnectionFactory(config);
}
#Bean
public RedisTemplate<String, Object> redisTemplate() {
RedisTemplate<String, Object> template = new RedisTemplate<>();
template.setEnableTransactionSupport(true);
template.setConnectionFactory(jedisConnectionFactory());
return template;
}
}
