5.6.9.4. CRD 模板

Operator 用户必须了解哪个选项必填，而不是可选选项。您可为您的每个 CRD 提供模板，并以最小配置集作为名为 alm-examples 的注解。兼容 UI 会预先填充该模板，供用户进一步自定义。

该注解由一个 kind 列表组成，如 CRD 名称和对应的 Kubernetes 对象的 metadata 和 spec。

以下完整示例提供了 EtcdCluster、EtcdBackup 和 EtcdRestore 模板：

metadata:
  annotations:
    alm-examples: >-
      [{"apiVersion":"etcd.database.coreos.com/v1beta2","kind":"EtcdCluster","metadata":{"name":"example","namespace":"default"},"spec":{"size":3,"version":"3.2.13"}},{"apiVersion":"etcd.database.coreos.com/v1beta2","kind":"EtcdRestore","metadata":{"name":"example-etcd-cluster"},"spec":{"etcdCluster":{"name":"example-etcd-cluster"},"backupStorageType":"S3","s3":{"path":"<full-s3-path>","awsSecret":"<aws-secret>"}}},{"apiVersion":"etcd.database.coreos.com/v1beta2","kind":"EtcdBackup","metadata":{"name":"example-etcd-cluster-backup"},"spec":{"etcdEndpoints":["<etcd-cluster-endpoints>"],"storageType":"S3","s3":{"path":"<full-s3-path>","awsSecret":"<aws-secret>"}}}]
