Note

Deletion of the saved image is not allowed when it is associated with Scale group. Means, scale group count is greater than 0. You need to first terminate the associated scale group to delete the saved image.

Create New Node from Saved Images

  • To create a new node from the saved images, go to the saved images section.

  • Click on the ‘+ Create Node’ under the Actions section next to the same image from which you want to create a node.

Note

You can only create a same or a higher configuration node from your selected image.

Tip

  • If you want to keep the server associated with an image then image and server both will be chargeable.

All saved images are billed only for the disk space used i.e. at ₹ 4 per GB per month.(exclusive of 18% GST Rate).

  • Once you have selected the Node plan, then click the “Create” Button. It will take you to the final stage of the ‘Create Compute Node’ page.

  • Once you have selected your options, click Create. It will take a few minutes to set up the Node and you will take to the ‘Manage Node’ page.

Create Scale Group from Saved Image

  • To create a new scale group from the saved images, go to the saved images section.
