This sample tool provides an example of how to programmatically create, update, and delete SAP Data Warehouse Cloud artifacts. The tool, referred to as provisioner, is written in Python and demonstrates how to automate various SAP Data Warehouse Cloud provisioning activities. The provisioner can perform the following actions against SAP Data Warehouse Cloud tenants:
- create and remove spaces with a simplified command line
- bulk create and remove spaces using a CSV file
- create and remove connections in one, or many spaces
- create and remove shared objects from one space to another
- create scripts of multiple commands
- generate a HANA tables for monitoring and analytics
The syntax for provisioner commands can be found here.
Before installing and running the provisioner, the following configurations and 3rd party components must be available.
Required
- SAP Data Warehouse Cloud administrator access, i.e., user with DW Administrator privilege
- Python version 3.8 or higher
Optional
- Git (latest version)
- Access to an SAP HANA (on-prem or cloud) schema
To ensure success running this tool, please use the following steps to validate the software requirements.
Python
The provisioner tool requires Python 3.8 (or higher) to be available. Use the following command to verify the Python installation.
Note: the latest versions of Python include both python and python3 versions of the command to start Python.
ubuntu@ip-17-1-3-11:~$ python --version
Python 3.10.4
ubuntu@ip-17-1-3-11:~$
ubuntu@ip-17-1-3-11:~$ python3 --version
Python 3.10.4
ubuntu@ip-17-1-3-11:~$
Git
To retrieve the provisioner from GitHub, the command line version of Git is an easy way to download the project to a local directory. The project may also be downloaded from GitHub as a zip file using a browser.
C:\>git --version
git version 2.37.0.windows.1
C:\>
Clone or download this repository to a directory. In all the examples in this README, a sub-directory named "tools" will be used as the starting location for all operations.
The commands to download the project are similar for all major operating systems, i.e., Linux, Windows, and Mac OS X.
GitHub Download
The provisioner is available on the SAP-samples Github repository: DWC Provisioner. The tool can be downloaded as a zip file from Github or the tool can be cloned directly from Github using one of the following commands.
Ubuntu / Linux:
From the home directory of the user ubuntu:
ubuntu@myhostname:~$ mkdir tools
ubuntu@myhostname:~$ cd tools
ubuntu@myhostname:~/tools$ git clone https://github.com/SAP-samples/dwc-provisioner
Cloning into 'dwc-provisioner'...Windows
Open a command window (cmd):
c:\> mkdir c:\tools
c:\> cd c:\tools
c:\> git clone https://github.com/SAP-samples/dwc-provisioner
Cloning into 'dwc-provisioner'...MacOS
From a terminal session:
myuser@mymachine ~ % mkdir tools
myuser@mymachine ~ % cd tools
myuser@mymachine tools % git clone https://github.com/SAP-samples/dwc-provisioner
Cloning into 'dwc-provisioner'...
myuser@mymachine tools % Browser Download
Using a browser, navigate to the SAP-samples/dwc-provisioner repository and click the "Download ZIP" button. Save or move the ZIP file to the "tools" sub-directory and unzip the contents.
Python allows you to create "virtual environments" to help manage dependencies between installed packages and the versions of packages used in a specific project. It is a best practice to create a virtual environment for each project. Without a virtual enviroment, all Python packages are installed in the "global" space and all projects share the same package versions.
https://packaging.python.org/en/latest/guides/installing-using-pip-and-virtual-environments/
The Python virtual environment tool uses the typical Python installation process, i.e., pip.
Ubuntu
sudo apt install python3-venvWindows/MacOS
python -m pip install --user virtualenv
Python virtual environments must be explicity created and activated. The following command create a Python virtural environment in the dwc-provisioner directory.
ubuntu@ip-17-1-83-11:~/tools$ cd dwc-provisioner ubuntu@ip-17-1-83-11:~/tools/dwc-provisioner$ python3 -m venv .venv
Python virtual enviroments must be activated each time in a command/terminal window before using Python.
Ubuntu / Linux / Mac OS
Non-windows platforms activate the virtual enviroment by "sourcing in" the necessary enviroment to the current shell.
ubuntu@ip-17-1-83-11:~/tools/provisioner$ source .venv/bin/activate
(.venv) ubuntu@ip-17-1-83-11:~/tools/provisioner$ Note: the the (.venv) prefix has been added to the command line prompt.
Windows
Windows activates the virtual enviroment by executing a batch script.
c:\devpath\dwc-provisioning> .venv\scripts\activateIf the environment is activated correctly, a previx (.venv) is shown in the command line:
(.venv) c:\devpath\dwc-provisioning>The provisioner requires publically available Python packages to be installed before running the tool. The packages are quickly installed using the following command:
(.venv) c:\tools\dwc-provisioner> python -m pip install -r requirements/core.txtTo create and store information about SAP Data Warehouse Cloud in an SAP HANA Cloud instance, ensure the IP address where this tool runs is in the allow list for SAP HANA Cloud connections. In the example below, an SAP Data Warehouse Cloud Data Access User (a.k.a., hash-tag (#) user) is the target, so in SAP Data Warehouse Cloud set the IP Allow list under the System / Configuration tab.
To start using the provisioner, a configuration file is created to identify the target SAP Data Warehouse Cloud tenant and set the username and password values.
Refer to the command sytax for additional information on the config command.
c:\> cd tools\dwc-provisioner
c:\> .venv\scripts\activate
(.venv) c:\tools\dwc-provisioner> provisioner config
--dwc-url https://{your-tenant}.{ds}.hcs.cloud.sap
--dwc-user [email protected]
--dwc-password NotYourPassword!
Notes:
- Command options are listed on separate lines for clarity.
- The change directory and starting the Python virtual environment commands are included for completeness.
To uninstall simply remove the dwc-provisioner directory, including all sub-directories
This sample application is in an early stage of development, so:
- don't store personal information because of missing access logging
- don't store sensitive information because there is no access control
- don't use the example application productively because users and passwords generated by the config command, while obfuscated, are not securely encrypted.
- don't expect always meaningful error messages in reaction to erroneous input.
This an example application not supported by SAP. However, you can create an issue in this repository if you find a bug or have questions about the content.
