I'm trying to run a vert.x java app inside a docker container. The app connects to a zookeeper instance running on another host. Connectivity to the zookeeper instance has been tested from the host and container. The app runs fine when I run it directly on the host. However, when I try to run the jar file inside the container it throws an error stating the following:
我正在尝试在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它时,应用程序运行正常。但是,当我尝试在容器内运行jar文件时,它会抛出一个错误,说明以下内容:

Your exception indicates that binding fails, I'm pretty sure the values you set for your zookeeper config are either not set or invalid.
您的异常表示绑定失败,我很确定您为zookeeper配置设置的值未设置或无效。
Debug the values of ${zookeeper.host}, ${zookeeper.cluster.host} and ${zookeeper.cluster.port}and if they're not set configure them properly
调试$ {zookeeper.host},$ {zookeeper.cluster.host}和$ {zookeeper.cluster.port}的值,如果没有设置,请正确配置它们

when you run the docker instance
当您运行docker实例时
docker run --network host
docker run --network host
The problem is the interface (and the address) you are trying to bind to is not available inside the docker (inside the container it's usually 172.17.x.x)
问题是您尝试绑定的接口(和地址)在docker中不可用(在容器内部通常是172.17.x.x)
when you specify the the host type networking (read here for more info https://docs.docker.com/network/#scope-of-this-topic) the container can use the ip of the host
当你指定主机类型网络时(在这里阅读更多信息https://docs.docker.com/network/#scope-of-this-topic)容器可以使用主机的IP
