Create Image

Introduction

A Virtual Compute Node image is an image template that provides the functionality to launch new node instances from your saved images. The image backups can be saved as a customized image with updated configurations.

Important

To create an image of a Windows node, please follow these steps:

1. Power off the node — This ensures data consistency and prevents file system corruption during image creation.
2. Click on "Save Image" from the Node Actions dropdown menu — This will initiate the image creation process.

To save an image of a virtual node (excluding Windows nodes), simply click on Save Image from the Actions menu.

Enter the Name for your Image and click on the Save Image button.

A popup message will appear indicating that your image is being saved.

Note

All the management operations will be disabled on this node while the image is being saved.

Manage your Image

To access your saved images, you need to click on the Saved Images button on the Manage Node page.

Saved Image Actions

Rename Saved Image

To rename your existing saved image, click on the Rename under the Actions section. The "Change Image Name" window will open, where you need to specify the new name and click on the Update Image button.

Move Saved Image To Another Project

You can transfer your image from its current project to another project within the same CRN.

Note

To transfer an image:

1. Ensure the image is not in Deleting or Error state.
2. Ensure no Auto-scaling is configured using the image.
3. The image must not have any Tags attached.

To transfer an image, click Move To Another Project from Actions.

Now, select the target project, check the checkbox, and click Transfer.

Export Image To Object Storage

To export an existing saved image, click Export To Object Storage under the Actions section.

Enter the bucket credentials of the destination where you want to export your image:

• Bucket Name - Select from the dropdown.
• Access Key - A unique identifier used to specify which account or user is making a request to cloud services.
• Secret Key - A confidential key paired with the access key, used to securely sign and authenticate requests.

After entering the details, click the Confirm button.

After clicking the Confirm button, the image will be exported to your EOS bucket.

Delete Saved Image

To delete an existing saved image, click on the Delete under the Actions section. A confirmation message will appear, click on the Delete Image button to confirm the deletion of the saved image.

Note

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

Create New Node from Saved Images

1. Go to the Saved Images section on the Manage Node page.
2. Click + Create Node under the Actions menu next to the image you want to use.

3. You will be taken to the Select Plan page with your saved image pre-selected as the OS. Choose your preferred:
   • Category (Linux Virtual Node or Linux Smart Dedicated Compute)
   • Instance Type (C3, E1, or M3)
   • Plan (vCPU, RAM, and storage configuration)
   • Instance Pricing (On-Demand or Savings Plan)

Note

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

4. Configure additional options on the same page — backup, networking, security group, SSH keys, volumes, and advanced settings. A live Summary panel on the right shows your estimated cost as you go.

5. Click Launch to create the node. You will be redirected to the Manage Nodes page once provisioning begins.

tip

If you want to keep the server associated with an image, both the image and the server will be chargeable. All saved images are billed only for the disk space used, i.e., ₹ 4 per GB per month (exclusive of 18% GST rate).

Create Scale Group from Saved Image

• To create a new scale group from the saved images, go to the saved images section.
• Click on the + Create Scale Group under the Actions section next to the image you want to use.

Note

You can only use C series and M series saved images to create a scale group. Deletion of the saved image is not allowed when it is associated with a scale group.

• Select a plan of your choice from a wide range of suitable options for various requirements and proceed with creating your scale group.

Hint

The compute node plan for the scale group can be different from the original plan used to create a saved image.

• Once you have selected the plan, click the Create button. It will take you to the final stage of the ‘Create Scale Group’ page.

Here, you need to specify the scale group name, scale parameters, scaling policy, and scaling period policy for the scale group you're creating. Click here to know more.

• Click the Create Scale button to launch scale group nodes with the selected policy. It will take a few minutes to set up the scale group, and you will be taken to the ‘Manage Application Scaling’ page.
