Describe the bug
Unable to connect Redis to Spring boot dockerize application
To reproduce
I'm using a Redis image for my Spring Boot application and its running perfectly in my local. However in docker-compose environment, although I have followed every instruction, document, tried every configuration, I still cannot connect it to my Dockerize Spring Boot application.

![Redis [BUG] Unable to connect to Redis](https://www.nineya.com/upload/2025/1/0303512119754726)
Expected behavior
Redis can connect to spring boot dockerize application
Comment From: sundb
@diegok what's the config in your spring app.
and you can first use redis-cli to check if you can connect Redis, if it works, then you need to make sure the spring config is correct.
Comment From: dvcminh
Hi, thank you for your reply. The config in my spring app is the application.yml I have sent above I do use redis-cli to ensure redis is healthy before my spring app can connect with it (you can see it in the docker-compose.yml file)
Comment From: iyahimovitz
Sounds like a docker DNS cache problem to me since you're trying to connect using redis but your health check is using localhost. I would try to telnet to redis using theredis hostname from app container and see if it connects.
Also, did you try to recreate the containers? sometimes that does help with DNS cache issues.
