Docker 机器和 Openstack / SSH

Question

我对 docker-machine 和 openstack 有疑问

运行这个命令 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

给我如下输出

然后当我尝试运行 docker-machine ls

我确定在 OpenStack 的机器上打开了端口 22、80 和 2376。

谢谢，如果有人可以帮助我，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

原答案：

在使用 openstack 驱动程序运行 docker-machine 0.6.0 时，我得到了同样的结果。但是 v0.7.0（构建 a650a40）对我来说效果很好。我正在运行一个不是 ubuntu 的 centos 映像，但在其他方面是一样的。抱歉，我有一段时间没有使用 docker-machine，但尝试获取最新版本，看看是否有帮助。

更新：

刚刚仔细检查了我上面运行的内容，我实际上使用环境变量配置了它，并在上面指定了一些额外的东西。不过具体来说，除了我的openstack RC file，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

然后跑：

docker-machine create -d=openstack testmachine
