Docker: Trying to run java vert.x app inside a container.

Question

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:

SLF4J: Actual binding is of type          [ch.qos.logback.classic.util.ContextSelectorStaticBinder]

    }

}

when you run the docker instance

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)

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

Your exception indicates that binding fails, I'm pretty sure the values you set for your zookeeper config are either not set or invalid.

Debug the values of ${zookeeper.host}, ${zookeeper.cluster.host} and ${zookeeper.cluster.port}and if they're not set configure them properly
