DESCRIPTION#
Evaluate objects against matching rules and output the results. Objects can be specified directly from the pipeline or provided from file.
The commands Invoke-PSRule and Assert-PSRule provide similar functionality, as differ as follows:
Invoke-PSRulewrites results as structured objectsAssert-PSRulewrites results as a formatted string.
EXAMPLES#
Example 1#
@{ Name = 'Item 1' } | Invoke-PSRule;
Evaluate a simple hashtable on the pipeline against rules loaded from the current working path.
Example 2#
# Define objects to validate
$items = @();
$items += [PSCustomObject]@{ Name = 'Fridge' };
$items += [PSCustomObject]@{ Name = 'Apple' };
# Validate each item using rules saved in current working path
$items | Invoke-PSRule;
TargetName: Fridge
RuleName Outcome Recommendation
-------- ------- --------------
isFruit Fail Fruit is only Apple, Orange and Pear
TargetName: Apple
RuleName Outcome Recommendation
-------- ------- --------------
isFruit Pass Fruit is only Apple, Orange and Pear
Evaluate an array of objects on the pipeline against rules loaded from the current working path.
Example 3#
# Define objects to validate
$items = @();
$items += [PSCustomObject]@{ Name = 'Fridge' };
$items += [PSCustomObject]@{ Name = 'Apple' };
# Validate each item and only return failing results
$items | Invoke-PSRule -Outcome Fail;
TargetName: Fridge
RuleName Outcome Recommendation
-------- ------- --------------
isFruit Fail Fruit is only Apple, Orange and Pear
Evaluate an array of objects, only failing object results are returned.
Example 4#
# Define objects to validate
$items = @();
$items += [PSCustomObject]@{ Name = 'Fridge' };
$items += [PSCustomObject]@{ Name = 'Apple' };
# Validate each item and show rule summary
$items | Invoke-PSRule -As Summary;
RuleName Pass Fail Outcome
-------- ---- ---- -------
isFruit 1 1 Fail
Evaluate an array of objects. The results for each rule is returned as a summary. Outcome is represented as the worst outcome.
PARAMETERS#
-Name#
The name of a specific rule to evaluate. If this parameter is not specified all rules in search paths will be evaluated.
Type: String[]
Parameter Sets: (All)
Aliases: n
Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False
-Path#
One or more paths to search for rule definitions within.
Type: String[]
Parameter Sets: (All)
Aliases: p
Required: False
Position: 0
Default value: None
Accept pipeline input: False
Accept wildcard characters: False
-Outcome#
Filter output to only show rule results with a specific outcome.
Type: RuleOutcome
Parameter Sets: (All)
Aliases:
Accepted values: Pass, Fail, Error, None, Processed, All
Required: False
Position: Named
Default value: Pass, Fail, Error
Accept pipeline input: False
Accept wildcard characters: False
-Tag#
Only get rules with the specified tags set. If this parameter is not specified all rules in search paths will be returned.
When more than one tag is used, all tags must match. Tags are not case sensitive.
A tag value of * may be used to filter rules to any rule with the tag set, regardless of tag value.
An array of tag values can be used to match a rule with either value.
i.e. severity = important, critical matches rules with a category of either important or critical.
Type: Hashtable
Parameter Sets: (All)
Aliases:
Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False
-InputObject#
The pipeline object to process rules for.
Type: PSObject
Parameter Sets: Input
Aliases: TargetObject
Required: True
Position: Named
Default value: None
Accept pipeline input: True (ByValue)
Accept wildcard characters: False
-Option#
Additional options that configure execution.
A PSRuleOption can be created by using the New-PSRuleOption cmdlet.
Alternatively, a hashtable or path to YAML file can be specified with options.
For more information on PSRule options see about_PSRule_Options.
Type: PSRuleOption
Parameter Sets: (All)
Aliases:
Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False
-As#
The type of results to produce. Detailed results are generated by default.
The following result formats are available:
Detail- Returns pass/ fail results for each rule per object.Summary- Returns summarized results for the rule and the worst outcome.
Type: ResultFormat
Parameter Sets: (All)
Aliases:
Accepted values: Detail, Summary
Required: False
Position: Named
Default value: Detail
Accept pipeline input: False
Accept wildcard characters: False
-Format#
Configures the input format for when a string is passed in as a target object.
When the -InputObject parameter or pipeline input is used, strings are treated as plain text by default.
Set this option to either Yaml, Json, Markdown, PowerShellData to have PSRule deserialize the object.
When the -InputPath parameter is used with a file path or URL.
If the Detect format is used, the file extension will be used to automatically detect the format.
When -InputPath is not used, Detect is the same as None.
When this option is set to File PSRule scans the path and subdirectories specified by -InputPath.
Files are treated as objects instead of being deserialized.
Additional, PSRule uses the file extension as the object type.
When files have no extension the whole file name is used.
See about_PSRule_Options for details.
This parameter takes precedence over the Input.Format option if set.
Type: InputFormat
Parameter Sets: (All)
Aliases:
Accepted values: None, Yaml, Json, Markdown, PowerShellData, File, Detect
Required: False
Position: Named
Default value: Detect
Accept pipeline input: False

Aliases:
Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False
-Culture#
Specifies the culture to use for rule documentation and messages. By default, the culture of PowerShell is used.
This option does not affect the culture used for the PSRule engine, which always uses the culture of PowerShell.
The PowerShell cmdlet Get-Culture shows the current culture of PowerShell.
