錯誤： No API token found for service account "default",

[root@kubernetes-master pods]# kubectl create -f mysql.yaml
Error from server (ServerTimeout): error when creating "mysql.yaml": No API token found for service account "default", retry after the token is automatically created and added to the service account

 

 

解決認證問題：

1去除認證

創建pod:

# kubectl create -f mysql.yaml
此時有如下報錯：

Error from server (ServerTimeout): error when creating "mysql.yaml": No API token found for service account "default", retry after the token is automatically created and added to the service account
解決辦法是編輯/etc/kubernetes/apiserver 去除 KUBE_ADMISSION_CONTROL中的SecurityContextDeny,ServiceAccount，並重啟kube-apiserver.service服務：

#vim /etc/kubernetes/apiserver
KUBE_ADMISSION_CONTROL="--admission_control=NamespaceLifecycle,NamespaceExists,LimitRanger,ResourceQuota"

#systemctl restart kube-apiserver.service
之后重新創建pod:

# kubectl create -f mysql.yaml
pod "mysql" created

2建立證書

To get your setup working, you can do the same thing local-up-cluster.sh is doing:

Generate a signing key: 
openssl genrsa -out /tmp/serviceaccount.key 2048

Update /etc/kubernetes/apiserver: 
KUBE_API_ARGS=”–service_account_key_file=/tmp/serviceaccount.key”

Update /etc/kubernetes/controller-manager: 
KUBE_CONTROLLER_MANAGER_ARGS=”–service_account_private_key_file=/tmp/serviceaccount.key”
