kublet配置：

###

# The address for the info server to serve on (set to 0.0.0.0 or "" for all interfaces)
KUBELET_ADDRESS="--address=0.0.0.0"

# The port for the info server to serve on
# KUBELET_PORT="--port=10250"

# You may leave this blank to use the actual hostname
KUBELET_HOSTNAME="kube-node1"

配置：

###
# kubernetes system config
#
# The following values are used to configure various aspects of all
# kubernetes services, including
#
#   kube-apiserver.service
#   kube-controller-manager.service
#   kube-scheduler.service
#   kubelet.service
#   kube-proxy.service
# logging to stderr means we get it in the systemd journal

# Should this cluster be allowed to run privileged docker containers
KUBE_ALLOW_PRIV="--allow-privileged=false"

# How the controller-manager, scheduler, and proxy find the apiserver
KUBE_MASTER="--master=http://kube-master:8080"

云配置：

user-id = nova
api-key = password
region = RegionOne
tenant-id = service
tenant-name = service

不知道我在这里错过了什么。不幸的是，openstack提供程序的代码没有告诉您参数何时丢失或格式错误。任何帮助都将不胜感激。

这在github上讨论过：

用户名和密码受支持，但用户id和api密钥显然不受支持。

这可能是由配置文件引起的。我建议删除所有可选或不需要的键，然后重试。需要检查的另一件事是证书。我在上面发布了我的配置，您能告诉我哪些密钥可能导致问题吗？请尝试使用以下内容：[Global]auth url用户名密码区域租户ID这可能是由配置文件引起的。我建议删除所有可选或不需要的键，然后重试。需要检查的另一件事是证书。我在上面发布了我的配置，您能告诉我哪些密钥可能导致问题吗？请尝试使用以下内容：[Global]auth url用户名密码区域租户id
