Docker-machine和Openstack / SSH

Question

我对docker-machine和openstack有问题

运行此命令docker-machine --debug create -d openstack --openstack-username admin --openstack-password admin --openstack-tenant-name admin --openstack-auth-url http://163.172.5.197:5000/v2.0 --openstack-flavor-id bea5cb42-c0b3-46fd-96a6-2f4c5d4448c2 --openstack-image-id 871a5ddf-a888-4b45-9201-78da07e6cdcb testmachine

给出了如下输出

然后当我尝试运行docker-machine ls时

Ubuntu 14.04.4 LTS testmachine ttyS0

testmachine login: 

我精确地指出，在OpenStack上，机器上的端口22、80和2376是打开的。

谢谢，如果有人能帮我，那就太好了

Answer 1

TL;DR尝试添加以下选项：

• --openstack-net-id或--openstack-net-name
• --openstack-floatingip-pool
• --openstack-sec-groups

原始答案

当我使用openstack驱动程序运行docker-machine 0.6.0时，我得到了完全相同的结果。但是v0.7.0 (build a650a40)对我来说工作得很好。我运行的是centos镜像，不是ubuntu，而是其他相同的镜像。很抱歉，我已经有一段时间没有使用docker-machine了，但试着抓取最新的版本，看看是否有帮助。

更新

只需仔细检查我在上面运行的内容，我实际上使用环境变量对其进行了配置，并指定了一些附加于上面的内容。具体来说，除了我的openstack RC file之外，我还设置了：

export OS_SSH_USER=centos
export OS_IMAGE_ID=c31637b9-455a-4849-8f46-2af1715f9dee
export OS_FLAVOR_NAME=m1.small
export OS_FLOATINGIP_POOL=INTERNAL-NETWORK
export OS_SECURITY_GROUPS=default
export OS_NETWORK_ID=b32e2700-8eac-4b7c-b9a8-16b6403927a2

然后运行：

docker-machine create -d=openstack testmachine
