PodSecurityPolicy(PSP)是一种用于配置和管理Kubernetes中Pod安全性策略的资源对象。它可以定义哪些安全规则和限制应用于Pod的创建和执行。
要配置和管理PodSecurityPolicy,请按照以下步骤:
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,您可以通过创建ClusterRoleBinding将该ClusterRole绑定到用户或服务账户:
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
通过以上步骤,您就可以配置和管理Kubernetes中的PodSecurityPolicy,以确保Pod的安全性。
