zookeeper operator如何进行权限设置 - 问答

在Apache ZooKeeper中，权限设置是通过ACL（Access Control List）来实现的。ZooKeeper提供了两种ACL：简单ACL和高级ACL。简单ACL使用用户、角色和权限来定义访问控制，而高级ACL使用更细粒度的规则来定义访问控制。

以下是使用ZooKeeper Operator进行权限设置的步骤：

首先，确保你已经安装了ZooKeeper Operator。你可以使用以下命令安装：

kubectl create namespace zookeeper
kubectl apply -f https://github.com/pravega/zookeeper-operator/releases/latest/download/zookeeper_operator.yaml

创建一个ZooKeeper集群。你可以使用ZooKeeper Operator的Custom Resource Definition (CRD)来创建一个ZooKeeper集群。例如，创建一个名为my-zookeeper的集群：

apiVersion: zookeeper.pravega.io/v1alpha1
kind: ZookeeperCluster
metadata:
  name: my-zookeeper
spec:
  size: 3
  version: "3.7.0"
  storage:
    type: persistentVolume
    persistentVolume:
      storageClassName: standard
      accessModes: [ "ReadWriteOnce" ]
      resources:
        requests:
          storage: 10Gi

创建一个ZooKeeper用户和角色。你可以使用ZooKeeper Operator的Role-Based Access Control (RBAC)来创建用户和角色。例如，创建一个名为my-user的用户，并为其分配一个名为my-role的角色：

apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
  name: my-role
  namespace: zookeeper
rules:
- apiGroups: ["", "extensions", "apps"]
  resources: ["*"]
  verbs: ["get", "list", "watch", "create", "update", "patch", "delete"]
---
apiVersion: rbac.authorization.k8s.io/v1
kind: RoleBinding
metadata:
  name: my-user-binding
  namespace: zookeeper
subjects:
- kind: User
  name: my-user
roleRef:
  kind: Role
  name: my-role

为ZooKeeper集群分配用户和角色。你可以使用ZooKeeper Operator的ZookeeperCluster CRD的spec.users字段来为用户分配角色。例如，为my-zookeeper集群分配my-user和my-role：

apiVersion: zookeeper.pravega.io/v1alpha1
kind: ZookeeperCluster
metadata:
  name: my-zookeeper
spec:
  size: 3
  version: "3.7.0"
  storage:
    type: persistentVolume
    persistentVolume:
      storageClassName: standard
      accessModes: [ "ReadWriteOnce" ]
      resources:
        requests:
          storage: 10Gi
  users:
  - name: my-user
    roles:
    - name: my-role

完成以上步骤后，my-user将具有访问my-zookeeper集群的权限。你可以根据需要创建更多的用户和角色，并根据实际需求分配相应的权限。
