我试图在docker容器中运行vert.x java app。该应用程序连接到在另一台主机上运行的zookeeper实例。已经从主机和容器测试了与zookeeper实例的连接。当我直接在主机上运行应用程序时运行正常。但是，当我尝试在容器内运行jar文件时，它会引发错误，说明以下内容：

运行docker实例时
docker run -网络主机
问题是您要绑定的接口（和地址）在docker内部（通常在容器内部172.17.x.x）不可用
当您指定主机类型的网络连接（有关更多信息，请阅读此处https://docs.docker.com/network/#scope-of-this-topic）时，容器可以使用主机的ip
答案 1 :(得分：0)
您的异常表示绑定失败，我非常确定您为zookeeper配置设置的值未设置或无效。
调试library(stringi)
json <- stringi::stri_trans_general(json, "latin-ascii")
，${zookeeper.host}和${zookeeper.cluster.host}的值，如果未设置，请正确配置
