Use CreateAssociationBatch with an Amazon SDK or CLI

To create multiple associations

This example associates a configuration document with multiple instances. The output returns a list of successful and failed operations, if applicable.

Command:

aws ssm create-association-batch --entries "Name=AWS-UpdateSSMAgent,InstanceId=i-1234567890abcdef0" "Name=AWS-UpdateSSMAgent,InstanceId=i-9876543210abcdef0"

Output:

Example 1: This example associates a configuration document with multiple instances. The output returns a list of successful and failed operations, if applicable.

$option1 = @{InstanceId="i-0cb2b964d3e14fd9f";Name=@("AWS-UpdateSSMAgent")}
$option2 = @{InstanceId="i-0000293ffd8c57862";Name=@("AWS-UpdateSSMAgent")}
New-SSMAssociationFromBatch -Entry $option1,$option2

Output:
