在Debian上安装Kubernetes时,权限设置是一个重要的环节。以下是一些关键步骤和注意事项,以确保安装过程的顺利进行和系统的安全性。
useradd 命令创建新用户,例如:sudo useradd zhangsan
openssl genrsa -out zhangsan.key 2048
openssl req -new -key zhangsan.key -out zhangsan.csr -subj "/CNzhangsan/OCSDN"
openssl x509 -req -days 3650 -CA /etc/kubernetes/cert/ca.pem -CAkey /etc/kubernetes/cert/ca-key.pem -CAcreateserial -in zhangsan.csr -out zhangsan.crt
apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
namespace: default
name: pod-reader
rules:
- apiGroups: [""]
resources: ["pods"]
verbs: ["get", "watch", "list"]
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
name: node-reader
rules:
- apiGroups: [""]
resources: ["nodes"]
verbs: ["get", "list"]
apiVersion: rbac.authorization.k8s.io/v1
kind: RoleBinding

apiGroup: rbac.authorization.k8s.io
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding

subjects:
- kind: User
name: zhangsan
apiGroup: rbac.authorization.k8s.io
roleRef:
kind: ClusterRole
name: node-reader
apiGroup: rbac.authorization.k8s.io
kubectl 命令验证用户权限:kubectl auth can-i list pods --as=zhangsan
通过以上步骤和注意事项,可以在Debian上成功安装并配置Kubernetes,同时确保系统的权限设置符合安全要求。建议在生产环境中根据具体需求进行详细配置和测试。
