# Use `CreateAssociation` with a CLI
<a name="example_ssm_CreateAssociation_section"></a>

The following code examples show how to use `CreateAssociation`.

------
#### [ CLI ]

**AWS 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": {
            "Date": 1487875500.33,
            "Message": "Associated with AWS-UpdateSSMAgent",
            "Name": "Associated"
        },
        "Name": "AWS-UpdateSSMAgent",
        "InstanceId": "i-0cb2b964d3e14fd9f",
        "Overview": {
            "Status": "Pending",
            "DetailedStatus": "Creating"
        },
        "AssociationId": "b7c3266e-a544-44db-877e-b20d3a108189",
        "DocumentVersion": "$DEFAULT",
        "LastUpdateAssociationDate": 1487875500.33,
        "Date": 1487875500.33,
        "Targets": [
            {
                "Values": [
                    "i-0cb2b964d3e14fd9f"
                ],
                "Key": "InstanceIds"
            }
        ]
    }
}
```

**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:  

```

            }
        ]
    }
}
```

**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:  

```
