我正在做docker入门指南： docs.docker/get-started/part3/#recap-and-cheat-sheet-optional

I'm doing the docker getting started guide: docs.docker/get-started/part3/#recap-and-cheat-sheet-optional

docker -compose.yml：

version: "3" services: web: # replace username/repo:tag with your name and image details image: username/repo:tag deploy: replicas: 5 resources: limits: cpus: "0.1" memory: 50M restart_policy: condition: on-failure ports: - "80:80" networks: - webnet networks: webnet:

我通过运行 docker stack deploy -c docker-compose.yml getstartedlab 部署了我的应用程序。 然后从curl上访问我的服务，它可以正常工作 curl -4 http：// localhost

I deployed my app by running docker stack deploy -c docker-compose.yml getstartedlab. Then Accessing my service from curl which working fine curl -4 localhost

<h3>Hello World!</h3><b>Hostname:</b> 1532cae6e06f<br/>....

但是我无法从Chrome或邮递员访问它通过转到 http：// localhost：80 （它将永远加载）。为什么以及如何解决它？

But I can't access it from chrome or postman by going to localhost:80 (it loads forever). Why and how can I fix it?

我可以从以下浏览器访问我的服务： 192.168.1.68:80 。 这是领导节点的地址（也是我的真实机器的IP。）。

I can access my service in the browser from: 192.168.1.68:80 . It is the address of the leader node (which is the ip of my real machine also..).

但是为什么我不能

推荐答案

看到 curl -4 ... 使我怀疑这是ipv6问题。如果未为ipv6配置本地计算机，并且localhost在hosts文件中引用了ipv6地址，则对localhost的调用将挂起。

Seeing the curl -4 ... makes me suspect this is an ipv6 issue. If your local machine isn't configured for ipv6 and localhost has a reference to the ipv6 address in the hosts file, then calls to localhost will hang.

很简单，在您的网址中转到 127.0.0.1 而不是 localhost 。

The workaround is rather simple, go to 127.0.0.1 instead of localhost in your urls.
