**To add one or more tags to a specified resource**

The following ``add-tags-to-resource`` example adds three tags to ``sample-cluster``. One tag (``CropB``) has a key name but no value. ::

    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"

This command produces no output.
