How to work with DreamCompute in Windows

1. Download the latest Python release from Python's website:
   • python.org/downloads/windows
2. After clicking the most recent Python 3 release, choose to download the Windows X86-64 executable installer.
3. Install Python by double-clicking the file you just downloaded.

Use the command prompt to install the OpenStack client.

Windows 10

1. On the bottom left, type cmd into the search bar.
2. Click on the Command Prompt icon to open it
3. In the command prompt, enter the following:

   C:\Users\username> pip3 install python-openstackclient
   

Error message: When installing, you may see this error.

error: Microsoft Visual C++ 14.0 is required. 
Get it with "Build Tools for Visual Studio": 
https://visualstudio.microsoft.com/downloads/

To fix this:

1. Download the vs_buildtools.exe file.
2. Click the file to run it.

   A pop-up window displays.

3. Under Desktop & Mobile select C++ build tools.
4. Click Install.

After C++ Build tools has been installed, run the command again to install the openstackclient.

You must now set environment variables for your Windows user so your OpenStack client commands are authenticated against your project. The easiest way to do this is to download your openrc file, modify/re-save it as a Windows batch file, and execute it once.

Downloading your openrc file

View the following article for instructions:

• How to download your DreamCompute openrc file

Modify the file

Once you've downloaded your openrc file, you'll need to modify/re-save it as a batch file. Open the file in a text editor like Notepad and remove everything except the following lines:

export OS_AUTH_URL=https://iad2.dream.io:5000/v2.0
export OS_TENANT_ID=tenantid
export OS_TENANT_NAME="tenantname"
export OS_USERNAME="username"

Make the following adjustments to the file:

• Replace all instances of export with setx
• Place double quote marks (") around all of your variable values (i.e. "https://iad2.dream.io:5000/v2.0", "tenantid", etc.).
• Replace the = sign with a space
• Add a line using OS_USERNAME to store your DreamCompute password

The file should now look like this:

setx OS_AUTH_URL "https://iad2.dream.io:5000/v2.0"
setx OS_TENANT_ID "tenantid"
setx OS_TENANT_NAME "tenantname"
setx OS_USERNAME "username"
setx OS_PASSWORD "password"

Save the file with the extension .bat (example: dhc-openrc.bat).

Execute the file

You must now execute the script as an administrator.

1. Locate the saved file in Windows Explorer.
2. Right-click and select the Run as administrator option.

After running the script, all necessary environmental variables should be set. However, they are not set in your current Shell session. You must now quit your current shell session and open a new one.

Open a new cmd prompt

Quit your current shell session by typing exit. Finally, open a new cmd prompt. Your environmental variables will now be active. You can confirm my running the command set.

You can now use the OpenStack command line client to manage your DreamCompute project. For a review of some of the basic commands, view the following article:
