使用 Docker 教程我被困在这部分：https://docs.docker.com/get-started/part3/#run-your-new-load-balanced-app https://docs.docker.com/get-started/part3/#run-your-new-load-balanced-app
I use curl -4 http://localhost但我得到了curl: (7) Failed to connect to localhost port 80: Connection refused error.
上一步的输出：docker service ps getstartedlab_web
ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS
kqu5qggifnlm getstartedlab_web.1 s1mpl3/get-started:part2 moby Running Running 29 minutes ago

r625x2k7n6ta getstartedlab_web.5 s1mpl3/get-started:part2 moby Running Running 29 minutes ago
So error and ports是空的。
我应该分析什么来解决这个问题？
对于第 4 部分，当您部署到 swarm 时，您将获得一个 URLdocker-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
docker-compose.yml 文件中的更改80:80 to 4000:80
Use 192.168.99.100:4000它应该可以工作。
