Kubernetes 首次创建Pod报错No API token found for service account "default", retry after the token is auto

Kubernetes 初始集群创建首个Pod时候报错：

Error from server (ServerTimeout): error when creating "hello-world-pod.yaml": No API token found for service account "default", retry after the token is automatically created and added to the service account

解决方案：

1）禁用ServiceAccount

编辑/etc/kubernetes/apiserver:

删除配置文件中KUBE_ADMISSION_CONTROL的ServiceAccount的选项

即将：KUBE_ADMISSION_CONTROL="--admission-control=NamespaceLifecycle,NamespaceExists,LimitRanger,SecurityContextDeny,ServiceAccount,ResourceQuota"

改为：KUBE_ADMISSION_CONTROL="--admission-control=NamespaceLifecycle,NamespaceExists,LimitRanger,SecurityContextDeny,ResourceQuota"

2）配置ServiceAccount

1：首先生成密钥

openssl genrsa -out /etc/kubernetes/serviceaccount.key 2048

2： 编辑/etc/kubernetes/apiserver

添加内容

KUBE_API_ARGS="--service_account_key_file=/etc/kubernetes/serviceaccount.key"

3：编辑/etc/kubernetes/controller-manager

添加内容

KUBE_CONTROLLER_MANAGER_ARGS="--service_account_private_key_file=/etc/kubernetes/serviceaccount.key"

重启对应的服务： systemctl restart etcd kube-apiserver kube-controller-manager kube-scheduler

重新创建Pod， ok
