get-default-patch-baseline

Description

Retrieves the default patch baseline. Amazon Web Services Systems Manager supports creating multiple default patch baselines. For example, you can create a default patch baseline for each operating system.

If you don’t specify an operating system value, the default patch baseline for Windows is returned.

See ‘aws help’ for descriptions of global parameters.

Synopsis

  get-default-patch-baseline
[--operating-system <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--operating-system (string)

Returns the default patch baseline for the specified operating system.

Possible values:

• WINDOWS

• AMAZON_LINUX

• AMAZON_LINUX_2

• UBUNTU

• REDHAT_ENTERPRISE_LINUX

• SUSE

• CENTOS

• ORACLE_LINUX

• DEBIAN

• MACOS

• RASPBIAN

• ROCKY_LINUX

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those 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. This may not be specified along with --cli-input-yaml.

--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. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.
