问题
I am running a simple rest app with redis running in a docker container/docker-compose. I believe, redis must be accessible to spring boot using http://redis:6379. But, it throws the error:
018-07-22 21:53:33.972 ERROR 1 --- [nio-8080-exec-1] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.data.redis.RedisConnectionFailureException: Cannot get Jedis connection; nested exception is redis.clients.jedis.exceptions.JedisConnectionException: Could not get a resource from the pool] with root cause
java.net.ConnectException: Connection refused (Connection refused)
My code is here.

Since you are using alias in links, you have to use the hostname identical to the alias to access the container. Therefore you can do one of following,
use http://localhost:6379 instead of http://redis:6379 in your spring boot application
or,
change
links:
- "redis:localhost"
to
links:
- "redis"
