docker Get started part 4: Accessing your cluster cannot curl

1. 问题描述

docker Get started part 4 can't visit myvm1 or myvm2.

curl: (7) Failed to connect to 192.168.99.* port 4000: Connection refused

docker 入门教程第四部分无法访问VM的地址

2. 解决方案

停止所有服务，从集群里脱离，重新创建的myvm1和myvm2

# stop getstartedlab
docker stack rm getstartedlab

# remove myvm1 and myvm2
$ docker-machine ssh myvm2 "docker swarm leave"
$ docker-machine ssh myvm1 "docker swarm leave --force"

# Unsetting docker-machine shell variable settings
$ eval $(docker-machine env -u)

# stop and remove myvm1, myvm2
$ docker-machine stop myvm1
$ docker-machine stop myvm2
$ docker-machine rm myvm1
$ docker-machine rm myvm2

# create myvm1, myvm2
$ docker-machine create --driver virtualbox --virtualbox-boot2docker-url=https://github.com/boot2docker/boot2docker/releases/download/v18.06.1-ce/boot2docker.iso myvm1
$ docker-machine create --driver virtualbox --virtualbox-boot2docker-url=https://github.com/boot2docker/boot2docker/releases/download/v18.06.1-ce/boot2docker.iso myvm2
