AWS CLI Commands for Patch Manager

The section includes examples of CLI commands that you can use to perform Patch Manager configuration tasks.

For an illustration of using the AWS CLI to patch a server environment by using a custom patch baseline, see Tutorial: Patch a Server Environment (AWS CLI).

For more information about using the CLI for AWS Systems Manager tasks, see the AWS Systems Manager section of the AWS CLI Command Reference.

Topics

Create a patch baseline

The following command creates a patch baseline that approves all critical and important security updates for Windows Server 2012 R2 five days after they are released. In addition, the patch baseline has been tagged to indicate that it is for a production environment.

aws ssm create-patch-baseline --name "Windows-Server-2012R2" --tags "Key=Environment,Value=Production" --approval-rules "PatchRules=[{PatchFilterGroup={PatchFilters=[{Key=MSRC_SEVERITY,Values=[Important,Critical]},{Key=CLASSIFICATION,Values=SecurityUpdates},{Key=PRODUCT,Values=WindowsServer2012R2}]},ApproveAfterDays=5}]" --description "Windows Server 2012 R2, Important and Critical security updates"

The system returns information like the following.

{
   "BaselineId":"pb-0c10e65780EXAMPLE"
}

Create a patch baseline with custom repositories for different OS versions

Applies to Linux instances only. The following command shows how to specify the patch repository to use for a particular version of the Amazon Linux operating system. This sample uses a source repository enabled by default on Amazon Linux 2017.09, but could be adapted to a different source repository that you have configured for an instance.

Note
To better demonstrate this more complex command, we are using the --cli-input-json option with additional options stored an external JSON file.

  1. Create a JSON file with a name like my-patch-repository.json and add the following content to it:

    {
    "Description": "My patch repository for Amazon Linux 2017.09",
    "Name": "Amazon-Linux-2017.09",
    "OperatingSystem": "AMAZON_LINUX",
    "ApprovalRules": {
        "PatchRules": [
            {
                "ApproveAfterDays": 7,
                "EnableNonSecurity": true,
                "PatchFilterGroup": {
                    "PatchFilters": [
                        {
                            "Key": "SEVERITY",
                            "Values": [
                                "Important",
                                "Critical"
                            ]
                        },
                        {
                            "Key": "CLASSIFICATION",
                            "Values": [
                                "Security",
                                "Bugfix"
                            ]
                        },
                        {
                            "Key": "PRODUCT",
                            "Values": [
                                "AmazonLinux2017.09"
                            ]
                        }
                    ]
                }
            }
        ]
    },
    "Sources": [
        {
            "Name": "My-AL2017.09",
            "Products": [
                "AmazonLinux2017.09"
            ],
            "Configuration": "[amzn-main] \nname=amzn-main-Base\nmirrorlist=http://repo./$awsregion./$awsdomain//$releasever/main/mirror.list //nmirrorlist_expire=300//nmetadata_expire=300 \npriority=10 \nfailovermethod=priority \nfastestmirror_enabled=0 \ngpgcheck=1 \ngpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-amazon-ga \nenabled=1 \nretries=3 \ntimeout=5\nreport_instanceid=yes"
        }
    ]
}

  2. In the directory where you saved the file, run the following command:

    aws ssm create-patch-baseline --cli-input-json file://my-patch-repository.json

    The system returns information like the following:

    {
    "BaselineId": "pb-12343b962ba63wxya"
}

Update a patch baseline

The following command adds two patches as rejected and one patch as approved to an existing patch baseline.

Note
For information about accepted formats for lists of approved patches and rejected patches, see About Package Name Formats for Approved and Rejected Patch Lists.
