PodSecurityPolicy(PSP)是一種用于配置和管理Kubernetes中Pod安全性策略的資源對象。它可以定義哪些安全規則和限制應用于Pod的創建和執行。
要配置和管理PodSecurityPolicy,請按照以下步驟:
apiVersion: policy/v1beta1
kind: PodSecurityPolicy
metadata:
name: my-pod-security-policy
spec:
privileged: false
allowPrivilegeEscalation: false
defaultAllowPrivilegeEscalation: false
runAsUser:
rule: RunAsAny
seLinux:
rule: RunAsAny
fsGroup:
rule: RunAsAny
supplementalGroups:
rule: RunAsAny
readOnlyRootFilesystem: false
volumes:
- '*'
kubectl apply -f my-pod-security-policy.yaml
kind: ClusterRole
apiVersion: rbac.authorization.k8s.io/v1
metadata:
name: psp:my-pod-security-policy
rules:
- apiGroups:
- policy
resources:
- podsecuritypolicies
resourceNames:
- my-pod-security-policy
verbs:
- use
然后,您可以通過創建ClusterRoleBinding將該ClusterRole綁定到用戶或服務賬戶:
kind: ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
name: psp:my-pod-security-policy-binding
subjects:
- kind: User
name: user1
apiGroup: rbac.authorization.k8s.io
roleRef:
kind: ClusterRole
name: psp:my-pod-security-policy
apiGroup: rbac.authorization.k8s.io
通過以上步驟,您就可以配置和管理Kubernetes中的PodSecurityPolicy,以確保Pod的安全性。
