instanceIds

The IDs of the managed nodes where the command should run. Specifying managed node IDs is most useful when you are targeting a limited number of managed nodes, though you can specify up to 50 IDs.

To target a larger number of managed nodes, or if you prefer not to list individual node IDs, we recommend using the Targets option instead. Using Targets, which accepts tag key-value pairs to identify the managed nodes to send commands to, you can a send command to tens, hundreds, or thousands of nodes at once.

For more information about how to use targets, see Run commands at scale in the Amazon Web Services Systems Manager User Guide.
