describe-instance-patches

Description

Retrieves information about the patches on the specified managed node and their state relative to the patch baseline being used for the node.

See also: AWS API Documentation

describe-instance-patches is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: Patches

Options

--instance-id (string)

The ID of the managed node whose patch state information should be retrieved.

--filters (list)

Each element in the array is a structure containing a key-value pair.

Supported keys for DescribeInstancePatches include the following:

  • **Classification ** Sample values: Security | SecurityUpdates
  • **KBId ** Sample values: KB4480056 | java-1.7.0-openjdk.x86_64
  • **Severity ** Sample values: Important | Medium | Low
  • **State ** Sample values: Installed | InstalledOther | InstalledPendingReboot For lists of all State values, see Understanding patch compliance state values in the Amazon Web Services Systems Manager User Guide .

(structure)

Defines a filter used in Patch Manager APIs. Supported filter keys depend on the API operation that includes the filter. Patch Manager API operations that use PatchOrchestratorFilter include the following:

  • DescribeAvailablePatches
  • DescribeInstancePatches
  • DescribePatchBaselines
  • DescribePatchGroups

Key -> (string)

The key for the filter.

Values -> (list)

The value for the filter.

(string)

Shorthand Syntax:

Key=string,Values=string,string ...

JSON Syntax:

[
  {
    "Key": "string",
    "Values": ["string", ...]
  }
  ...
]

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command's output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command's output. If the total number of items available is more than the value specified, a NextToken is provided in the command's output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

Example 1: To get the patch state details for an instance

The following describe-instance-patches example retrieves details about the patches for the specified instance.

aws ssm describe-instance-patches \
    --instance-id "i-1234567890abcdef0"

Output:

{
    "Patches": [
        {
            "Title": "2019-01 Security Update for Adobe Flash Player for Windows Server 2016 for x64-based Systems (KB4480979)",
            "KBId": "KB4480979",
            "Classification": "SecurityUpdates",
            "Severity": "Critical",
            "State": "Installed",
            "InstalledTime": "2019-01-09T00:00:00+00:00"
        },
        {
            "Title": "",
            "KBId": "KB4481031",
            "Classification": "",
            "Severity": "",
            "State": "InstalledOther",
            "InstalledTime": "2019-02-08T00:00:00+00:00"
        },
        ...
    ],
    "NextToken": "--token string truncated--"
}

Example 2: To get a list of patches in the Missing state for an instance

The following describe-instance-patches example retrieves information about patches that are in the Missing state for the specified instance.

aws ssm describe-instance-patches \
    --instance-id "i-1234567890abcdef0" \
    --filters Key=State,Values=Missing

Output:

{
    "Patches": [
        {
            "Title": "Windows Malicious Software Removal Tool x64 - February 2019 (KB890830)",

        },
        ...
    ],
    "NextToken": "--token string truncated--"
}

For more information, see About Patch Compliance States in the AWS Systems Manager User Guide.

Example 3: To get a list of patches installed since a specified InstalledTime for an instance

The following describe-instance-patches example retrieves information about patches installed since a specified time for the specified instance by combining the use of --filters and --query.

aws ssm describe-instance-patches \
    --instance-id "i-1234567890abcdef0" \
    --filters Key=State,Values=Installed \
    --query "Patches[?InstalledTime >= `2023-01-01T16:00:00`]"

Output:

{
    "Patches": [
        {
            "Title": "2023-03 Cumulative Update for Windows Server 2019 (1809) for x64-based Systems (KB5023702)",
            "KBId": "KB5023702",
            "Classification": "SecurityUpdates",
            "Severity": "Critical",
            "State": "Installed",
            "InstalledTime": "2023-03-16T11:00:00+00:00"
        },
        ...
    ],
    "NextToken": "--token string truncated--"
}
