function Invoke-ATSSMShellScript { <# .SYNOPSIS Run shell script on hosts using SSM AWS-RunShellScript. .DESCRIPTION Run shell script on hosts using SSM AWS-RunShellScript. .PARAMETER InstanceIds List of instance IDs identifying instances to run the script on. .PARAMETER AsJson If set, attempt to parse command output as a JSON string and convert to an object. .PARAMETER AsText Print command output from each instance to the console .PARAMETER UseS3 SSM truncates results to 2000 characters. If you expect results to exceed this, then this switch instructs SSM to send the results to S3. The cmdlet will retrieve these results and return them. .PARAMETER CommandText String containing shell commands to run. .PARAMETER ExecutionTimeout The time in seconds for a command to be completed before it is considered to have failed. Default is 3600 (1 hour). Maximum is 172800 (48 hours). .PARAMETER Deliverytimeout The time in seconds for a command to be delivered to a target instance. Default is 600 (10 minutes). .OUTPUTS [PSObject], none If -AsText specified, then none Else List of PSObject, one per instance containing the following fields - InstanceId Instance for which this result pertains to - ResultObject If -AsJson and the result was successfully parsed, then an object else NULL - ResultText Standard Output returned by the script (Write-Host etc.) .NOTES aws-toolbox uses a working bucket for passing results through S3 which will be created if not found. Format of bucket name is aws-toolbox-workspace-REGIONNAME-AWSACCOUNTID .EXAMPLE Invoke-ATSSMShellScript -InstanceIds i-00000000 -AsText { ls -la / } Returns directory listing from remote instance to the console. #> [CmdletBinding(DefaultParameterSetName = 'AsText')] param ( [Parameter(Mandatory=$true)] [string[]]$InstanceIds, [Parameter(Mandatory=$true, Position = 0)] [string]$CommandText, [Parameter(ParameterSetName = 'AsJson')] [switch]$AsJson, [Parameter(ParameterSetName = 'AsText')] [switch]$AsText, [switch]$UseS3, [int]$ExecutionTimeout = 3600, [int]$DeliveryTimeout = 600 ) $invokeArguments = @{ ScriptType = 'Shell' } $PSBoundParameters.Keys | ForEach-Object { $invokeArguments.Add($_, $PSBoundParameters[$_]) } Invoke-SSMCommandScript @invokeArguments } |
