使用 AWS CLI 的 Amazon DocumentDB 示例

为指定资源添加一个或多个标签

以下 add-tags-to-resource 示例向 sample-cluster 添加三个标签。一个标签（CropB）有键名但没有值。

aws docdb add-tags-to-resource \
    --resource-name arn:aws:rds:us-west-2:123456789012:cluster:sample-cluster \
    --tags Key="CropA",Value="Apple" Key="CropB" Key="CropC",Value="Corn"

此命令不生成任何输出。

有关更多信息，请参阅《Amazon DocumentDB 开发人员指南》中的标记 Amazon DocumentDB 资源。

在下一个维护时段内执行待处理的维护操作

以下 apply-pending-maintenance-action 示例在下一个计划维护时段内执行所有 system-update 操作。

aws docdb apply-pending-maintenance-action \
--resource-identifier arn:aws:rds:us-west-2:123456789012:cluster:sample-cluster \
--apply-action system-update \
--opt-in-type next-maintenance

此命令不生成任何输出。

复制现有的数据库集群参数组

以下 copy-db-cluster-parameter-group 示例复制名为 custom-docdb3-6-copy 的参数组 custom-docdb3-6。创建副本时，它会将标签添加到新的参数组中。

aws docdb copy-db-cluster-parameter-group \
    --source-db-cluster-parameter-group-identifier custom-docdb3-6 \
    --target-db-cluster-parameter-group-identifier custom-docdb3-6-copy \
    --target-db-cluster-parameter-group-description "Copy of custom-docdb3-6" \
    --tags Key="CopyNumber",Value="1" Key="Modifiable",Value="Yes"

输出：

{
    "DBClusterParameterGroup": {
        "DBParameterGroupFamily": "docdb3.6",
        "DBClusterParameterGroupArn": "arn:aws:rds:us-east-1:12345678901:cluster-pg:custom-docdb3-6-copy",
        "DBClusterParameterGroupName": "custom-docdb3-6-copy",
        "Description": "Copy of custom-docdb3-6"
    }
}

复制快照

以下 copy-db-cluster-snapshot 示例创建名为 sample-cluster-snapshot-copy 的 sample-cluster-snapshot 的副本。副本包含原始标签的所有标签以及带有键名 CopyNumber 的新标签。

aws docdb copy-db-cluster-snapshot \
    --source-db-cluster-snapshot-identifier sample-cluster-snapshot \
    --target-db-cluster-snapshot-identifier sample-cluster-snapshot-copy \
    --copy-tags \
    --tags Key="CopyNumber",Value="1"

此命令不生成任何输出。

aws docdb create-db-cluster-parameter-group \
    --db-cluster-parameter-group-name sample-parameter-group \
    --db-parameter-group-family docdb3.6 \
    --description "Sample parameter group based on docdb3.6"

输出：

    "DBClusterParameterGroup": {
        "Description": "Sample parameter group based on docdb3.6",
        "DBParameterGroupFamily": "docdb3.6",
