我在谷歌云平台的CentOS 7实例上本地运行eclipse。 我能够在我的浏览器上获得che界面，但无法启动项目。
来自我的che.properties文件的
machine.docker.local_node_host=172.17.0.1
api.endpoint=http://_my instance external IP_:${SERVER_PORT}/ide/api
（putted manualy）：
172.17.0.1 che-host
安装Docker作为预先要求

这发生在启动工作区代理阶段，在以下阶段之后
Initializing workspace ... completed
Starting workspace runtime ... completed
```
我从che github repo的那些人那里得到的答案是：
这里的问题是浏览器尝试连接到工作区代理，它使用CHE_DOCKER_MACHINE_HOST，服务器也使用CHE_DOCKER_MACHINE_HOST ping ws-agent。
因此，docker0应该是外部可用的IP。
所以，我从中了解到172.17.0.1也需要有外部IP，
知道如何将IP从默认的docker0 IP切换到$(document).ready(function() {
$(".demoClass").click(function() {
$("#dialog-1").dialog({
resizable: false,
height: 140,
modal: true,
buttons: [{
text: "Yes",
click: function() {
$(this).dialog("close");
},
}, {
text: "No",
click: function() {
$(this).dialog("close");
},
}
],
});
});
});
接口的外部IP吗？
