Create Amazon Machine Image (AMI)

Amazon Machine Images (AMIs) are virtual machine templates used to launch EC2 instances in AWS. An AMI includes the operating system, application software, and configuration data required to start an instance. While EC2 Hosts in DuploCloud represent dedicated physical servers, AMIs serve as reusable blueprints for creating virtual server instances. You can create and manage AMIs directly in the DuploCloud Portal to support consistent and scalable deployments.

Adding an AMI

1. In the DuploCloud Portal, navigate to Cloud Services → Hosts. The Hosts page displays.

2. In the NAME column, select the host you want to use as the basis for your AMI.

3. Click the Actions menu and select Host Settings → Create AMI. The Create AMI pane displays.

   
4. Complete the following fields:

   AMI Name

   Enter a name for the new AMI.

   Share With All Tenants

   Enable this option to make the AMI available to all tenants in the environment.

   Shared With Tenants

   If not sharing with all tenants, select one or more specific tenants to share the AMI with.

5. Click Create to generate the AMI. You can monitor its status on the AMI tab of the Hosts page.

Viewing and Editing an AMI

1. In the DuploCloud Portal, navigate to Cloud Services → Hosts.

2. Select the AMI tab.

3. Click the Name of an AMI to open its details page and view overview information such as creation date, source host, and sharing scope.

4. To update the AMI’s sharing settings, click Actions → Edit from the AMI details page. Here you can:

   • Enable or disable Share With All Tenants.

   • Select specific tenants to share the AMI with.

   • Keep the AMI tenant-scoped (private).

Launching a New Host from an AMI

You can create a new host based on an existing AMI to deploy a server with your custom configuration.

When creating a host in DuploCloud, check the box to display Advanced Options, and select your desired AMI from the Image ID dropdown.

Disabling Host creation for custom AMIs

You can disable host creation by non-administrators (Users) for custom AMIs by configuring the option in DuploCloud.

Configuring the Disable Host Creation with Custom AMI option

1. In the DuploCloud Portal, navigate to Administrator -> System Settings.

2. Click the System Config tab.

3. Click Add. The Add Config pane displays.

4. In the Config Type list box, select Flags.

5. In the Key list box, select Disable Host Creation with Custom AMI.

6. In the Value list box, select true.

7. Click Submit.

When this setting is configured, the Other option in the Image ID list box in the Add Host page, will be disabled, preventing hosts with custom AMIs from being created.
