Use the Instance Provisioner to create a new Instance in OpenStack Cloud and launch it.
The Instance Provisioner walks you through the following steps to creating a new OpenStack Instance:
- Selecting an image
- Specifying hardware and networking details
- Confirming launch settings
- Launching the Instance
Use the following procedure to create a new Instance in OpenStack using the Instance Provisioner.
- Navigate to Clouds > OpenStack > Instances > New. The Image screen of the Instance Provisioner displays.
- In the left-hand pane, select the machine image you want to use for your Instance. You can use the filter controls to help you locate the images that are of interest to you. The information displayed in the right-hand pane provides specific details on the selected image. Once you have chosen an appropriate image, click Details to move to the next screen. Note that you can also use the 'breadcrumbs' at the top of the screen to navigate through the various steps of the Instance Provisioner.
The Details screen provides the following fields and controls for configuring the hardware and storage settings for your Instance.
