我正在EC2实例上将Spring Boot应用程序作为Docker容器运行。 我已经创建了redis集群（AWS上的弹性缓存）并在运行中和静止时启用了加密。
就VPC和安全组配置而言，一切都是正确的。 问题是，当我看到Spring Boot应用日志时，它会抛出

我敢肯定，redis集群是可以访问的，因为我有另一个具有相同配置的redis集群，除了传输中加密和禁用了静态休息对我来说都很好。
这是我的docker文件快照（我使用的是ENV变量而不是application.yml）：
ENV SPRING_REDIS_HOST m.d-r-s.us.usblahe2.cblhaahe.amazonaws.com ENV SPRING_REDIS_SSL是 ENV SPRING_REDIS_PASSWORD blahblahblahblah ENV SPRING_REDIS_JEDIS_POOL_MAX_ACTIVE 8 ENV SPRING_REDIS_JEDIS_POOL_MAX_IDLE 8 ENV SPRING_REDIS_JEDIS_POOL_MAX_WAIT -1ms ENV SPRING_REDIS_JEDIS_POOL_MIN_IDLE 0
更新：我尝试从同一ec2实例（运行java spring boot应用程序的地方）使用stunnel，并且能够访问redis集群。
