Launching an Instance Using an Existing Instance as a Template

You can use an existing instance as a template to launch another instance, either in the public Cloud or in a Virtual Private Cloud (VPC).

When launching an instance using an existing instance, the following attributes are duplicated from the existing instance:

  • Name

  • OUTSCALE machine image (OMI)

  • Instance type

  • VPC

  • Subnet

  • Availability Zone (AZ)

  • Security group(s)

  • Keypair

This action does not clone the existing instance, it only duplicates its attributes. To create an exact copy of your instance, you can create an OMI from the instance and then launch an instance from this OMI. For more information, see Creating an OMI from an Instance.

You can review and modify these attributes before confirming the launch of the instance. You can also modify these attributes after launching the instance. For more information, see Modifying an Instance Attribute.

Open the Create Instance From dialog box

  1. Click Compute > Instances.

  2. Select the instance whose attributes you want to reuse.

  3. Click Create From…​ .
    The CREATE INSTANCE FROM…​XXX dialog box appears.

Modify the attributes of the instance

  1. (optional) To modify the name of the instance:

    1. Click the Name tab.

    2. In the text field, type a name for the instance.

      This action adds a Name tag of 255 characters maximum. You can use any character, including accented letters.

  2. (optional) To modify the OMI:

    1. Click the Outscale Machine Image tab.

    2. From the list, select the OMI you want to create your instance from.

  3. (optional) To modify the instance type:

    1. Click the Instance Type tab.

    2. Specify the following attributes for your instances:

      • CPU: The processor generation.

      • Performance: The performance flag.

        • Highest Performance: Provides maximum compute capacity on all the cores of the VM. This option is ideal for intensive compute applications.

        • High Performance: Provides high compute capacity on all the cores of the VM. This option offers small performance variability and applies to most cases.

        • Medium Performance: Provides performance with significant variability on all the cores of the VM. This option does not guarantee consistent performance, but is ideal for machines with low CPU demand.

      • Core(s): The number of vCores, up to 78.

      • Memory (GiB): The amount of memory, up to 1039 GiB.

    For more information about instance types, see Instance Types.

    To function properly, Windows instances require at least a v3 processor generation, 2 vCores, and 4 GiB of memory.

  4. (optional) To add, modify, or remove a VPC:

    1. Click the VPC tab.

    2. From the list, select the VPC in which you want to launch the instance, or the VPC you want to remove.

  5. (optional, VPC only) To modify the subnet:

    1. Click the Subnet tab.

    2. From the list, select the subnet in which you want to launch the instance.

  6. (optional) To modify the Availability Zone:

    1. Click the Availability Zone tab.

    2. From the list, select the AZ in which you want to launch the instance.

      When you launch the instance in a VPC, the AZ in which the instance is launched depends on the selected subnet.

  7. (optional) To modify the security groups:

    1. Click the Security Groups tab.

    2. From the list, select the security group(s) you want to associate with the instance.

      Multiselection is available.

  8. (optional) To modify the keypair:

    1. Click the Keypairs tab.

    2. From the list, select the keypair you want to assign to the instance.
      To launch instances using Cockpit, you must always specify a keypair, even when the OMI used does not require one. For more information, see About Keypairs.

Confirm the launch of the instance
