Getting started with image templates

With IBM Cloud® Classic infrastructure image templates, you can capture an image of a virtual server to quickly replicate its configuration with minimal changes in the order process. Image templates provide an imaging option for all Virtual Servers, regardless of operating system. Image templates are not compatible with bare metal servers.

Image templates are not intended for backing up your data.

How image templates work

The two main actions for any image template are create and deploy. When you request to create an image, the automated system of IBM Cloud® takes your server offline. While the server is offline, a compressed backup of your data is created, the configuration information is recorded, and the image template is stored on the IBM Cloud SAN. During the deployment stage of the image template, the automated system constructs a new server that is based on the data that is gathered from the selected image. The deployment process makes adjustments for volume, restores the copied data, and then makes final configuration changes (for example, network configurations) for the new host.

Private images

Private images are images that are created by users on their own accounts or images that are created on another account and shared. By default, all the images that you create are private.

Public images

Public images are pre-configured virtual servers that are posted by IBM Cloud or made public by customers and are available for use by all IBM Cloud customers. Virtual servers that are provisioned through public image templates are generally configured for optimal performance, with specific combinations of different configuration specs.

ISO images of licensed operating systems, such as Windows and Red Hat Enterprise Linux, and open source operating systems, such as CentOS and Ubuntu, are not provided by IBM. If you need these ISO images, you can download them from the respective vendor website.

Creating an image template

Complete the following steps to create an image template of a virtual server.

Go to your console's device menu and make sure that you have the correct account permissions to complete the tasks.
From the Devices menu, select Device List.
Click the virtual server that you want to use to create an image template.

Check the Passwords tab of the Device Details page. Ensure that any passwords listed on the Device Details page match the actual operating system passwords and any other software add-on passwords. If passwords do not match, virtual servers that are created from this image template fail.
From the Actions menu, select Create Image Template and complete the required fields.

For more information, see Creating an image template.

Next steps

After the image template is created, you can order more virtual servers based on the template. Your new virtual servers have the same configurations that are included in the image template.
