The following script shows how to extend EnvBuilder by implementing a subclass which installs setuptools and pip into a created virtual environment:.
This script is also available for download online. Navigation index modules next previous Python ». Note While symlinks are supported on Windows, they are not recommended. Note On Microsoft Windows, it may be required to enable the Activate. If specified, it is called with two arguments: a string indicating some progress, and a context indicating where the string is coming from.
The context argument can have one of three values: 'main', indicating that it is called from virtualize itself, and 'stdout' and 'stderr', which are obtained by reading lines from the output streams of a subprocess which is used to install the app. If a callable is not specified, default progress information is output to sys.

AzCopy V10 is just an executable file, so there's nothing to install. These files are compressed as a zip file Windows and Mac or a tar file Linux. To download and decompress the tar file on Linux, see the documentation for your Linux distribution. If you want to copy data to and from your Azure Table storage service, then install AzCopy version 7.
For convenience, consider adding the directory location of the AzCopy executable to your system path for ease of use. That way you can type azcopy from any directory on your system. If you choose not to add the AzCopy directory to your path, you'll have to change directories to the location of your AzCopy executable and type azcopy or. As an owner of your Azure Storage account, you aren't automatically assigned permissions to access data.
Before you can do anything meaningful with AzCopy, you need to decide how you'll provide authorization credentials to the storage service. This option is available for blob Storage only.
By using Azure Active Directory, you can provide credentials once instead of having to append a SAS token to each command. In the current release, if you plan to copy blobs between storage accounts, you'll have to append a SAS token to each source URL.
For examples, see Copy blobs between storage accounts. This example command recursively copies data from a local directory to a blob container. The Secure transfer required setting of a storage account determines whether the connection to a storage account is secured with Transport Layer Security TLS. It is displayed on the canvas as an arrow pointing from the source activity to the destination activity.
The activities run in the direction of the arrow with the destination activity starting after the source activity completes. You can create a link between two activities by selecting the source activity and clicking the circle at the bottom of the shape. Drag the arrow to the destination activity and release. Select the link to configure its properties in the Configuration blade.
Properties include the link type, which is described in the following table. A graphical runbook starts with any activities that do not have an incoming link. There is often only one activity that acts as the starting activity for the runbook. If multiple activities do not have an incoming link, the runbook starts by running them in parallel.
It follows the links to run other activities as each completes. When you specify a condition on a link, the destination activity runs only if the condition resolves to True. You typically use an ActivityOutput variable in a condition to retrieve the output from the source activity. For a pipeline link, you must specify a condition for a single object.
The runbook evaluates the condition for each object output by the source activity. It then runs the destination activity for each object that satisfies the condition. For example, with a source activity of Get-AzVM , you can use the following syntax for a conditional pipeline link to retrieve only virtual machines in the resource group named Group1. For a sequence link, the runbook only evaluates the condition once, since a single array containing all objects from the source activity is returned.
Because of this, the runbook can't use a sequence link for filtering, like it can with a pipeline link.
The sequence link can simply determine whether or not the next activity is run. The runbook uses three different sequence links that verify values of the input parameters VMName and ResourceGroupName to determine the appropriate action to take. When you use a conditional link, the data available from the source activity to other activities in that branch is filtered by the condition.
If an activity is the source to multiple links, the data available to activities in each branch depends on the condition in the link connecting to that branch. For example, the Start-AzVM activity in the runbook below starts all virtual machines. It has two conditional links. Any activity that follows the first link and uses the activity output from Get-AzureVM only retrieves the virtual machines that were started at the time when Get-AzureVM was run. Any activity that follows the second link only gets the virtual machines that were stopped at the time when Get-AzureVM was run.
Any activity following the third link gets all virtual machines regardless of their running state. A junction is a special activity that waits until all incoming branches have completed. This allows the runbook to run multiple activities in parallel and ensure that all have completed before moving on.
While a junction can have an unlimited number of incoming links, only one of those links can be a pipeline. The number of incoming sequence links is not constrained. You can create the junction with multiple incoming pipeline links and save the runbook, but it will fail when it is run. The example below is part of a runbook that starts a set of virtual machines while simultaneously downloading patches to be applied to those machines. It uses a junction to ensure that both processes are completed before the runbook continues.
A cycle is formed when a destination activity links back to its source activity or to another activity that eventually links back to its source. Graphical authoring does not currently support cycles. If your runbook has a cycle, it saves properly but receives an error when it runs.
Any data that an activity outputs with an outgoing link is written to the databus for the runbook. Any activity in the runbook can use data on the databus to populate parameter values or include in script code. An activity can access the output of any previous activity in the workflow. How the data is written to the databus depends on the type of link on the activity.
For a pipeline link, the data is output as multiple objects. For a sequence link, the data is output as an array. If there is only one value, it is output as a single-element array. The first mechanism uses an activity output data source to populate a parameter of another activity.
If the output is an object, the runbook can specify a single property. The second data access mechanism retrieves the output of an activity in a PowerShell expression data source or a workflow script activity with an ActivityOutput variable, using the syntax shown below. If the output is an object, your runbook can specify a single property. You can set checkpoints in a graphical PowerShell Workflow runbook by selecting Checkpoint runbook on any activity.
This causes a checkpoint to be set after the activity runs. Checkpoints are only enabled in graphical PowerShell Workflow runbooks, and are not available in graphical runbooks.
If the runbook uses Azure cmdlets, it should follow any checkpointed activity with a Connect-AzAccount activity. The connect operation is used in case the runbook is suspended and must restart from this checkpoint on a different worker.
A runbook requires input either from a user starting the runbook through the Azure portal or from another runbook, if the current one is used as a child. For example, for a runbook that creates a virtual machine, the user might need to provide such information as the name of the virtual machine and other properties each time the runbook starts.
The runbook accepts input by defining one or more input parameters. The user provides values for these parameters each time the runbook starts. When the user starts the runbook using the Azure portal, the user is prompted to provide values for each input parameter supported by the runbook. When authoring your runbook, you can access its input parameters by clicking Input and output on the runbook toolbar.
This opens the Input and Output control where you can edit an existing input parameter or create a new one by clicking Add input. Graphical authoring saves data created by any activity that does not have an outgoing link to the output of the runbook. The output is saved with the runbook job and is available to a parent runbook when the runbook is used as a child.
