Use CreateAssociation with a CLI

Example 1: To associate a document using instance IDs

This example associates a configuration document with an instance, using instance IDs.

aws ssm create-association \
    --instance-id "i-0cb2b964d3e14fd9f" \
    --name "AWS-UpdateSSMAgent"

Output:

{
    "AssociationDescription": {
        "Status": {

        },
        "Name": "AWS-UpdateSSMAgent",
        "InstanceId": "i-0cb2b964d3e14fd9f",
        "Overview": {
            "Status": "Pending",
            "DetailedStatus": "Creating"
        },
        "AssociationId": "b7c3266e-a544-44db-877e-b20d3a108189",

            }
        ]
    }
}

Example 2: To associate a document using targets

This example associates a configuration document with an instance, using targets.

aws ssm create-association \
    --name "AWS-UpdateSSMAgent" \
    --targets "Key=instanceids,Values=i-0cb2b964d3e14fd9f"

Output:

{
    "AssociationDescription": {
        "Status": {
            "Date": 1487875500.33,
            "Message": "Associated with AWS-UpdateSSMAgent",

        "Overview": {
            "Status": "Pending",
            "DetailedStatus": "Creating"
        },
        "AssociationId": "b7c3266e-a544-44db-877e-b20d3a108189",

            }
        ]
    }
}

Example 3: To create an association that runs only once

This example creates a new association that only runs once on the specified date and time. Associations created with a date in the past or present (by the time it is processed the date is in the past) run immediately.

aws ssm create-association \
    --name "AWS-UpdateSSMAgent" \
    --targets "Key=instanceids,Values=i-0cb2b964d3e14fd9f" \
    --schedule-expression "at(2020-05-14T15:55:00)"  \
    --apply-only-at-cron-interval

Output:

{
    "AssociationDescription": {
        "Status": {
            "Date": 1487875500.33,
            "Message": "Associated with AWS-UpdateSSMAgent",
            "Name": "Associated"
        },
        "Name": "AWS-UpdateSSMAgent",
        "InstanceId": "i-0cb2b964d3e14fd9f",
        "Overview": {

                "Key": "InstanceIds"
            }
        ]
    }
}
