我怀疑问题是您正在尝试通过 localhost 而不是 parent-host 连接到Redis>.创建Jedis连接时，请确保通过 parent-host 连接到Redis.

I suspect the problem is that you are trying to connect to redis via localhost rather than parent-host. Make sure that you are connecting to redis via parent-host when creating the Jedis connection.

-net = host 选项起作用的原因是，在这种情况下， localhost 将引用主机的IP，而不是容器的IP.

The reason --net=host option works, is that in this case localhost will refer to the IP of the host machine and not to that of the container.

此外，请确保容器内/etc/hosts 中的 parent-host 有一个实体.

Also, make sure that there is an enty for parent-host in /etc/hosts inside the container.
