问题描述
我的docker版本是1.13.1.我正在尝试从Docker容器连接到Redis服务器，但出现连接被拒绝错误.详细日志如下:
My docker version is 1.13.1.I am trying to connect to redis-server from my docker container,but I am getting connection refused error.Detailed logs are given below:
当我给出-net ="host" 选项时，此错误消失了，但是当我给出
when i give --net="host" option this error is gone,but when i give
--add-host=parent-host:`ip route show | grep docker0 | awk '{print \$9}'`
我得到了错误，尽管容器能够连接到不同VM上的Db，但不能连接到自托管计算机上的redis-server.
I get the error,although the container is able to connect to Db on a different VM,but not connecting to redis-server present on self hosting machine.
推荐答案
我怀疑问题是您正在尝试通过 localhost 而不是 parent-host .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.
