Function Invoke-DatabricksApiRequest { <# .SYNOPSIS Lists all jobs or returns a specific job for a given JobID. .DESCRIPTION Lists all jobs or returns a specific job for a given JobID. Official API Documentation: https://docs.databricks.com/api/latest/jobs.html#list Official API Documentation: https://docs.databricks.com/api/latest/jobs.html#get .PARAMETER Method The type of request you want to invoke. Will usually be GET or POST .PARAMETER EndPoint The API endpoint that you want to invoke. Please check the API reference for valid values. Example: "/2.0/jobs/list" .PARAMETER Body Some endpoints also support a body to supply additional information. This can be specified here. For POST requests, this is usually a JSON-string whereas for GET it is usually a hashtable which is then converted to URL parameters .EXAMPLE Invoke-DatabricksApiRequest -Method GET -EndPoint "/2.0/jobs/list" #> [CmdletBinding()] param ( [Parameter(Mandatory = $true, Position = 1)] [string] [ValidateSet("DEFAULT", "DELETE", "GET", "HEAD", "MERGE", "OPTIONS", "PATCH", "POST", "PUT", "TRACE")] $Method, [Parameter(Mandatory = $true, Position = 2)] [string] $EndPoint, [Parameter(Mandatory = $false, Position = 3)] $Body, [Parameter(Mandatory = $false, Position = 4)] $ContentType, [Parameter(Mandatory = $false, Position = 5)] $Accept ) Test-Initialized Write-Verbose "Setting final ApiURL ..." $apiUrl = Get-ApiUrl -ApiEndpoint $EndPoint Write-Verbose "API Call: $Method $apiUrl" #Set headers Write-Verbose "Building Headers ..." $headers = Get-RequestHeader $headers | Add-Property -Name "Content-Type" -Value $ContentType -Force $headers | Add-Property -Name "Accept" -Value $Accept -Force Write-Verbose "Headers: `n$($headers | Out-String)" if ($Method -eq "GET") { Write-Verbose "GET request - showing URL parameters as Key-Value pairs ..."

For Azure, this could be 'https://westeurope.azuredatabricks.net' For AWS, this could be 'https://abc-12345-xaz.cloud.databricks.com' .PARAMETER CloudProvider The CloudProvider where the Databricks workspace is hosted. Can either be 'Azure' or 'AWS'. If not provided, it is derived from the ApiRootUrl parameter and/or the type of authentication .PARAMETER Credential The Powershell credential to use when using AAD authentication. .PARAMETER ClientID The ID of the Azure Active Directory (AAD) application that was deployed to use AAD authentication with Databricks. If used in combination with -ServicePrincipal this value does not have to be supplied but is overwritten using the Usernamen from -Credential. .PARAMETER TenantID The ID of the Azure Active Directory (AAD). (optional) .PARAMETER AzureResourceID This is the ID of the workspace appliance resource in Azure. You must provide this ID if the Databricks workspace is not provisioned yet (such that there is no effective workspace org ID). It can be composed using the Azure subscription ID, resource group name, and workspace resource name. Example: /subscriptions/<<SubscriptionID>>/resourceGroups/<<ResourceGroupName>>/providers/Microsoft.Databricks/workspaces/<<WorkspaceName>> .PARAMETER OrgID The organization ID of the Databricks workspace. You can find the workspace org ID in the Databricks URL, for example: https://<region>.azuredatabricks.net/?o=<org_id> .PARAMETER SubscriptionID The Azure subscription ID in which the Databricks workspace resides. A GUID, e.g. 058a2e1e-1234-1234-1234-5c4c3e31e36e .PARAMETER ResourceGroupName The name of the ResourceGroup in which the Databricks workspace resides. .PARAMETER WorkspaceName The name of the Databricks workspace. .PARAMETER ServicePrincipal A switch indicating -Credential is a Service Principal which will be used for Authentication. .PARAMETER DynamicParameterCacheTimeout To improve performance during development dynamic paramters can be cached. This setting controls the number of seconds these values are persisted before the API is queried again for more recent values. .PARAMETER ApiCallRetryCount Number of times an API call is tried before an actual error is thrown. .PARAMETER ApiCallRetryWait Number of seconds to wait before retrying an API call. .EXAMPLE Set-DatabricksEnvironment -AccessToken "dapi1234abcd32101691ded20b53a1326285" -ApiRootUrl "https://abc-12345-xaz.cloud.databricks.com" .EXAMPLE Set-DatabricksEnvironment -AccessToken "dapi1234abcd32101691ded20b53a1326285" -ApiRootUrl "https://westeurope.azuredatabricks.net" .EXAMPLE $azureResourceId = '/subscriptions/fb1e20c4-1234-1234-1234-f92a9ac35db4/resourceGroups/myResourceGroupName/providers/Microsoft.Databricks/workspaces/myDatabricksResource' $cred = Get-Credential Set-DatabricksEnvironment -ClientID '058a2e1e-1234-1234-1234-5c4c3e31e36e' -Credential $cred -AzureResourceID $azureResourceId -ApiRootUrl "https://westeurope.azuredatabricks.net" #> [CmdletBinding()] param ( [Parameter(ParameterSetName = "DatabricksApi", Mandatory = $true, Position = 1)] [string] $AccessToken, [Parameter(ParameterSetName = "AADAuthenticationResourceID", Mandatory = $true, Position = 1)] [Parameter(ParameterSetName = "AADAuthenticationOrgID", Mandatory = $true, Position = 1)] [Parameter(ParameterSetName = "AADAuthenticationResourceDetails", Mandatory = $true, Position = 1)][PSCredential] $Credential, [Parameter(ParameterSetName = "AADAuthenticationResourceID", Mandatory = $true, Position = 2)] [Parameter(ParameterSetName = "AADAuthenticationOrgID", Mandatory = $true, Position = 2)] [Parameter(ParameterSetName = "AADAuthenticationResourceDetails", Mandatory = $true, Position = 2)][string] $ClientID, [Parameter(ParameterSetName = "AADAuthenticationResourceID", Mandatory = $true, Position = 4)] [Parameter(ParameterSetName = "AADAuthenticationOrgID", Mandatory = $true, Position = 4)] [Parameter(ParameterSetName = "AADAuthenticationResourceDetails", Mandatory = $true, Position = 4)] [string] $TenantID = "common", [Parameter(ParameterSetName = "AADAuthenticationResourceID", Mandatory = $true, Position = 3)] [string] $AzureResourceID, [Parameter(ParameterSetName = "AADAuthenticationOrgID", Mandatory = $true, Position = 3)] [string] $OrgID, [Parameter(ParameterSetName = "AADAuthenticationResourceDetails", Mandatory = $true, Position = 3)] [string] $SubscriptionID, [Parameter(ParameterSetName = "AADAuthenticationResourceDetails", Mandatory = $true, Position = 5)] [string] $ResourceGroupName, [Parameter(ParameterSetName = "AADAuthenticationResourceDetails", Mandatory = $true, Position = 6)] [string] $WorkspaceName, [Parameter(ParameterSetName = "AADAuthenticationResourceID", Mandatory = $false, Position = 7)] [Parameter(ParameterSetName = "AADAuthenticationOrgID", Mandatory = $false, Position = 7)] [Parameter(ParameterSetName = "AADAuthenticationResourceDetails", Mandatory = $false, Position = 7)][switch] $ServicePrincipal, [Parameter(Mandatory = $false, Position = 2)] [int] $DynamicParameterCacheTimeout = 5, [Parameter(Mandatory = $false, Position = 3)] [int] $ApiCallRetryCount = -1, [Parameter(Mandatory = $false, Position = 4)] [int] $ApiCallRetryWait = 10, [Parameter(Mandatory = $false, Position = 5)] [string] $CustomApiRootUrl ) DynamicParam { #Create the RuntimeDefinedParameterDictionary $Dictionary = New-Object System.Management.Automation.RuntimeDefinedParameterDictionary New-DynamicParam -Name ApiRootUrl -ValidateSet $script:dbApiRootUrls -DPDictionary $Dictionary #return RuntimeDefinedParameterDictionary return $Dictionary } begin { Write-Verbose "Setting [System.Net.ServicePointManager]::SecurityProtocol to [System.Net.SecurityProtocolType]::Tls12 ..."
