docker - 如何使Hazelcast Management Center在docker中找到其节点？

Question

我正在尝试使用docker设置hazelcast和管理中心以进行开发。不幸的是，管理中心找不到hazelcast节点。

我按照此处的指示在计算机上启动hazelcast和管理中心https://hub.docker.com/r/hazelcast/hazelcast

进入管理中心时，我会收到以下消息:



我试图以这种形式输入缺少的信息:



但是我找不到正确的值来使它工作。
有什么想法怎么了？

我使用以下命令来启动docker:

docker run -e JAVA_OPTS="-Dhazelcast.local.publicAddress=162.168.1.136:5701" -p 5701:5701 hazelcast/hazelcast:3.12.5
docker run -e MC_INIT_CMD="./mc-conf.sh cluster add -H=/data -ma 192.168.1.136:5701 -cn dev" -p 8080:8080 hazelcast/management-center:3.12.5

这给出了以下输出，对我来说看起来不错:

您使用Hazelcast(和管理中心)版本4.0的命令，但实际上运行的是图像3.12.5。管理中心的连接机制已更改。因此，您需要使用最新版本或应用instructions for 3.12.5，如下所示:

$ docker run -p 8080:8080 hazelcast/management-center:3.12.5
$ docker run -p 5701:5701 -e MANCENTER_URL="http://<host_ip>:8080/hazelcast-mancenter" -e JAVA_OPTS="-Dhazelcast.local.publicAddress=<host_ip>:5701" hazelcast/hazelcast:3.12.5
