docker – 继续使用：Stack服务器无休止地加载页面

我一直非常密切关注docker get started guide – 除了我的python应用程序中的一些更改,我已经确认这些更改从我推送到docker hub的版本没有问题.

但是,当我到达第3部分并尝试加载localhost：80时,页面只是无休止地加载.

我的命令：

$docker swarm init
Swarm initiated: ...
$docker stack deploy -c docker-compose.yml
Creating network getstartedlab_webnet
Creating service getstartedlab_web
$docker stack ps getstartedlab

最佳答案

在某些系统中,curl默认为localhost连接到ip6.所以你可以运行curl：

$curl 127.0.0.1:80

要么

$curl -4 localhost:80
