问题描述
使用Docker教程，我被困在这一部分: https://docs.docker.com/get-started/part3/#run-your-new-load-balanced-app
Using the Docker tutorial I'm stuck at this part: https://docs.docker.com/get-started/part3/#run-your-new-load-balanced-app
我使用curl -4 http://localhost，但出现curl: (7) Failed to connect to localhost port 80: Connection refused错误.
输出:docker service ps getstartedlab_web
ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS

所以error和ports为空.
我应该分析什么来解决此问题?

推荐答案
对于第4部分，当部署到集群时，您将获得带有docker-machine ls的URL.
For part 4 when you deploy to your swarm, you get an URL with docker-machine ls.
NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS
myvm1 * virtualbox Running tcp://192.168.99.100:2376 v17.10.0-ce
myvm2 - virtualbox Running tcp://192.168.99.101:2376 v17.10.0-ce
将docker-compose.yml文件80:80更改为4000:80
Change in docker-compose.yml file 80:80 to 4000:80
使用192.168.99.100:4000，它应该可以正常工作.
Use 192.168.99.100:4000 and it should be working.
