kublet並非以雲提供商“ openstack”開頭

Question

為了使用煤渣卷，我在我的kubelet配置中添加了--cloud-provider和--cloud-config選項：

$ cat /etc/kubernetes/kubelet
###
# kubernetes kubelet (node) config

# 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="--hostname_override=192.168.100.76"

# location of the api-server
KUBELET_API_SERVER="--api_servers=https://localhost:6443"

# Add your own!
KUBELET_ARGS="--cluster_dns=10.100.0.10 --cluster_domain=cluster.local --kubeconfig=/etc/kubernetes/kubelet.kubeconfig --config=/etc/kubernetes/manifests --cloud-provider=openstack --cloud-config=/etc/kubernetes/cloud_config"

我已經創建了具有必要憑據的文件：

$ sudo cat /etc/kubernetes/cloud_config
[Global]
auth-url=https://api.*********.com:5000/v2.0
user-id=kubecindertest
username=kubecindertest
password=*****
region=RegionOne
tenant-name=kubecindertest
tenant-id=6568768756a7886767e676f7efe76fe7
project-name=kubecindertest

（手動）啟動kubelet時，該過程僅記錄unknown cloud provider "openstack"並存在：

source /etc/kubernetes/kubelet; sudo /usr/bin/kubelet $KUBE_LOGTOSTDERR $KUBE_LOG_LEVEL $KUBELET_API_SERVER $KUBELET_ADDRESS $KUBELET_PORT $KUBELET_HOSTNAME $KUBE_ALLOW_PRIV $KUBELET_ARGS
unknown cloud provider "openstack"

在kubernetes存儲庫中定義openstack提供程序的openstack.go具有完全相同的名稱（小寫）：

const ProviderName =“ openstack”

更新

原來，該錯誤是解析配置文件時發生的期望。 我刪除了所有可選鍵或不需要的鍵，現在將其用作配置文件：

$ sudo cat /etc/kubernetes/cloud_config
[Global]
auth-url=https://api.*********.com:5000/v2.0
username=kubecindertest
password=*****
region=RegionOne
tenant-id=6568768756a7886767e676f7efe76fe7

但是，啟動Kublet僅會導致另一個錯誤：

第二個問題是證書問題。

Answer 1

錯誤消息在openstack cloud provider插件中不太清楚。 如果配置文件中沒有任何意外的字段，它將不會注冊，它將引發錯誤，不幸的是，該錯誤未正確冒泡。

這是插件可以識別的字段（及其標識符）

[Global] AuthUrl string gcfg：“ auth-url” Username string UserId string gcfg：“用戶ID” Password string ApiKey string gcfg：“ api-key” TenantId string gcfg：“ tenant-id” TenantName string gcfg：“ tenant- name“ DomainId DomainId string gcfg：”域ID“ DomainName string gcfg：”域名“ Region string

當然，並非所有課程都是必需的。 我通常有

[Global] auth-url username password region tenant-id
