AWS SSM check in ec2 instance

Question

I want to get a list of ec2 instances with no SSM installed.

I tried using boto3.describe_instance_information but getting an error.

https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/ssm.html#SSM.Client.describe_instance_information

Below is my code

import boto3


client = boto3.client('ssm')


response = client.describe_instance_information(
    InstanceInformationFilterList=[
        {
            'key': 'i-0187655667fghj',
            'valueSet': [
                'AgentVersion',
                'InstanceIds'
            ]
        }
    ]
)


print(response)

Error:

Traceback (most recent call last):
  File "ssm.py", line 13, in <module>
    'InstanceIds'
  File "/Library/Python/2.7/site-packages/botocore/client.py", line 357, in _api_call

    raise error_class(parsed_response, operation_name)

Answer 1

Did you read the documentation properly? As it accepts the Instance ID.

{
            'key': 'InstanceIds'|'AgentVersion'|'PingStatus'|'PlatformTypes'|'ActivationIds'|'IamRole'|'ResourceType'|'AssociationStatus',
            'valueSet': [
                'string',
            ]
        }

so you have to pass ID

import boto3


client = boto3.client('ssm')


response = client.describe_instance_information(
    InstanceInformationFilterList=[
        {
            'key': 'InstanceIds',
            'valueSet': [
                'i-0187655667fghj'
            ]
        }
    ]
)


print(response)

InstanceInformationFilterList

This is a legacy method. We recommend that you don't use this method. Instead, use the InstanceInformationFilter action. The InstanceInformationFilter action enables you to return instance information by using tags that are specified as a key-value mapping.

If you do use this method, then you can't use the InstanceInformationFilter action. Using this method and the InstanceInformationFilter action causes an exception error.

Type: Array of InstanceInformationFilter objects

Array Members: Minimum number of 0 items.

Required: No
