Use CreatePatchBaseline with a CLI

The following code examples show how to use CreatePatchBaseline.

CLI

AWS CLI

Example 1: To create a patch baseline with auto-approval

The following create-patch-baseline example creates a patch baseline for Windows Server that approves patches for a production environment seven days after they are released by Microsoft.

aws ssm create-patch-baseline \
    --name "Windows-Production-Baseline-AutoApproval" \
    --operating-system "WINDOWS" \
    --approval-rules "PatchRules=[{PatchFilterGroup={PatchFilters=[{Key=MSRC_SEVERITY,Values=[Critical,Important,Moderate]},{Key=CLASSIFICATION,Values=[SecurityUpdates,Updates,UpdateRollups,CriticalUpdates]}]},ApproveAfterDays=7}]" \
    --description "Baseline containing all updates approved for Windows Server production systems"

Output:

{
    "BaselineId": "pb-045f10b4f3EXAMPLE"
}

Example 2: To create a patch baseline with an approval cutoff date

The following create-patch-baseline example creates a patch baseline for Windows Server that approves all patches for a production environment that are released on or before July 7, 2020.

aws ssm create-patch-baseline \
    --name "Windows-Production-Baseline-AutoApproval" \
    --operating-system "WINDOWS" \
    --approval-rules "PatchRules=[{PatchFilterGroup={PatchFilters=[{Key=MSRC_SEVERITY,Values=[Critical,Important,Moderate]},{Key=CLASSIFICATION,Values=[SecurityUpdates,Updates,UpdateRollups,CriticalUpdates]}]},ApproveUntilDate=2020-07-07}]" \
    --description "Baseline containing all updates approved for Windows Server production systems"

Output:

{
    "BaselineId": "pb-045f10b4f3EXAMPLE"
}

Example 3: To create a patch baseline with approval rules stored in a JSON file

The following create-patch-baseline example creates a patch baseline for Amazon Linux 2017.09 that approves patches for a production environment seven days after they are released, specifies approval rules for the patch baseline, and specifies a custom repository for patches.

aws ssm create-patch-baseline \
    --cli-input-json file://my-amazon-linux-approval-rules-and-repo.json

        }
    ]
}

Example 4: To create a patch baseline that specifies approved and rejected patches

The following create-patch-baseline example explicitly specifies patches to approve and reject as exception to the default approval rules.

aws ssm create-patch-baseline \
    --name "Amazon-Linux-2017.09-Alpha-Baseline" \
    --description "My custom approve/reject patch baseline for Amazon Linux 2017.09 instances" \
    --operating-system "AMAZON_LINUX" \
    --approved-patches "CVE-2018-1234567,example-pkg-EE-2018*.amzn1.noarch" \
    --approved-patches-compliance-level "HIGH" \
    --approved-patches-enable-non-security \
    --tags "Key=Environment,Value=Alpha"

PowerShell

Tools for PowerShell

Example 1: This example creates a patch baseline that approves patches, seven days after they are released by Microsoft, for managed instances running Windows Server 2019 in a production environment.

$rule = New-Object Amazon.SimpleSystemsManagement.Model.PatchRule
$rule.ApproveAfterDays = 7

$ruleFilters = New-Object Amazon.SimpleSystemsManagement.Model.PatchFilterGroup

$patchFilter = New-Object Amazon.SimpleSystemsManagement.Model.PatchFilter
$patchFilter.Key="PRODUCT"
$patchFilter.Values="WindowsServer2019"

$severityFilter = New-Object Amazon.SimpleSystemsManagement.Model.PatchFilter
$severityFilter.Key="MSRC_SEVERITY"
$severityFilter.Values.Add("Critical")
$severityFilter.Values.Add("Important")
$severityFilter.Values.Add("Moderate")

$classificationFilter = New-Object Amazon.SimpleSystemsManagement.Model.PatchFilter
$classificationFilter.Key = "CLASSIFICATION"
$classificationFilter.Values.Add( "SecurityUpdates" )
$classificationFilter.Values.Add( "Updates" )
$classificationFilter.Values.Add( "UpdateRollups" )
$classificationFilter.Values.Add( "CriticalUpdates" )

$ruleFilters.PatchFilters.Add($severityFilter)
$ruleFilters.PatchFilters.Add($classificationFilter)
$ruleFilters.PatchFilters.Add($patchFilter)
$rule.PatchFilterGroup = $ruleFilters
