Creating virtual server instances

Creating virtual server instances

You can create one or more virtual server instances in your IBM Cloud VPC by using the IBM Cloud console, CLI, API, or Terraform.

When you create a virtual server, you specify information such as the location and name for your virtual server. You specify an operating system image, a profile that defines the combination of vCPU and RAM, and SSH keys to securely connect to your virtual server. You can add data volumes in addition to the boot volume. You can also specify the type of network interface that is created for your virtual server. Finally, you can select from advanced options for your virtual server configuration.

Creating a virtual server instance with the UI

Use the following steps to create a virtual server instance.

  1. In the IBM Cloud console, click Navigation menu icon menu icon > Infrastructure VPC icon > Compute > Virtual server instances.

  2. Click Create and begin by entering the information in Table 1.

    Selections to begin instance provisioning
    Field Value
    Location Locations are composed of regions (specific geographic areas) and zones (fault-tolerant data centers within a region). Select the location where you want to create your virtual server instance.
    Name A name is required for your virtual server instance.
    Resource group Select a resource group for the instance.
    Tags You can assign a user tag to the instance so that you can easily filter instance resources in your resource list. For more information, see Working with tags.
    Access management tags Access management tags help you apply flexible access policies on specific resources. For more information, see the Controlling access to resources by using tags UI tutorial.

  3. Select an image and profile for the instance. To select from all available images, click Change image. You can select an image, a snapshot of a boot volume, or an existing boot volume. If the geographic location where you are provisioning an instance supports it, you can select either x86 or s390x architecture. Table 2 describes image, snapshot, and existing volume options. Then, select a profile. To select from all available vCPU and RAM combinations, click Change profile. Table 3 describes profile selection.

    Instance provisioning image, snapshot, or volume selections
    Field Value
    Stock image

    Select from available stock images and click Save.

    • For more information about available stock images, see x86 virtual server images and s390x virtual server images. All operating system images use cloud-init that you can use to enter user metadata that is associated with the instance for post-provisioning scripts. Metadata isn't supported for IBM Cloud® Hyper Protect Virtual Server for IBM Cloud® Virtual Private Cloud instances and z/OS virtual server instances.
    • If you plan to use Windows operating systems with SQL Server, see the About Microsoft SQL on VPC.
    Custom image

    Select from available custom images and click Save. If no custom images are available, click Create.

    • A custom image can be an image that you customize and upload to IBM Cloud Object Storage, which you can then import into IBM Cloud VPC. For more information about custom images, see Getting started with custom images.
    • You can also use a custom image that was created from a boot volume. For more information about creating an image from a volume, see About creating an image from a volume.
    • You can also select either an RHEL or Windows custom image and bring your own license (BYOL). For more information about creating BYOL custom images, see Bring your own license.
    Catalog image

    After you select an available catalog image, click Select version and pricing plan, choose the version and pricing plan, and then click Save.
    Snapshot

    Select either Import existing snapshot or Import snapshot by CRN. UpdatedThen, choose a snapshot of a boot volume, and click Save. If no snapshots are available, click Create.

    • Filter the list of snapshots for fast restore. With this option, you can create the boot volume quickly by using a snapshot that is cached in a different zone of your region. For more information about restoring a volume from a snapshot, see Restoring a volume from a snapshot.
    • If you're using the CRN of a snapshot from another account, make sure that the right IAM authorizations are in place.
    Existing volume Select an existing boot volume that is not attached to an instance and click Save.
    Profile selections
    Field Value
    Profile The profile families are Balanced, Compute, Memory, Ultra High Memory, Very High Memory, GPU, and Confidential Compute. For more information, see x86-64 instance profiles. When you create an IBM Cloud Hyper Protect Virtual Servers for IBM Cloud® Virtual Private Cloud instance, make sure that you select secure execution-enabled profiles, otherwise provisioning fails. For more information, see s390x instance profiles.

    Some profiles might not be available because the number of network interfaces in the virtual server exceed profile limits. You can remove network interfaces to select from more profiles. For more information, see Resizing a virtual server.
    Advanced security selections
    Secure boot Click the toggle to enable secure boot. Secure boot is available with only compatible profiles. For more information about secure boot, see Secure boot for Virtual Servers for VPC.
    Confidential computing - SGX Select availability Confidential computing with Intel® Software Guard Extensions (SGX) protects your data through hardware-based server security by using isolated memory regions that are known as encrypted enclaves. SGX is available with only compatible profiles. For more information about confidential computing, see Confidential computing with Intel Software Guard Extensions (SGX) for Virtual Servers for VPC.

    Secure boot and confidential computing are available with balanced and compute profiles. For more information, see SGX-compatible profiles.

  4. Complete SSH keys, storage, and networking details by specifying the information in Table 4.

    Selections to complete instance provisioning
    Field Value
    SSH keys You must select an existing public SSH key or click Create an SSH key to create one. For more information about creating an SSH key, see Creating your SSH key by using the UI. SSH keys are used to securely connect to the instance after it's running.
    Note: Alpha-numeric combinations are limited to 100 characters. SSH keys can be either RSA or ED25519. You can create only RSA SSH keys. For an ED25519 SSH key, you must upload the key information. ED25519 can be used only if the operating system supports this key type. ED25519 can't be used with Windows or VMware images.
    For more information, see Getting started with SSH keys.
    Boot volume The default boot volume size for most profiles is 100 GB. The default boot volume size for a z/OS virtual server instance is 245 GB. If you're importing a custom image, the boot volume capacity can be 10 - 250 GB, depending on what the image requires. Images that are smaller than 10 GB are rounded up to 10 GB. click the Edit icon Edit icon to modify the boot volume's attributes in the side panel.
    You can change the name of the boot volume by specifying a unique, meaningful name. For example, it can be a name that describes your compute or workload function. The volume name must begin with a lowercase letter. The name can be up to 63 lowercase alpha-numeric characters and include the hyphen (-). Volume names must be unique the entire VPC infrastructure. You can edit the name later if you want to.
    You can toggle the auto-delete option off for the boot volume. If it is enabled, then the volume is deleted when the instance is deleted. If it is disabled, then the volume persists after the instance is deleted.
    You can specify optional user tags and access management tags to associate with this volume. For more information about organizing resources with user tags, see Working with tags.
    You can select the encryption type. Provider-managed encryption is enabled by default on all volumes. You can also choose to create an envelop encryption with your own root keys. Encryption keys are created and maintained in Key Management Services (Key Protect or Hyper Protect Crypto Services).
    You can increase the size of the boot volume up to 250 GB.
    Data volumes You can create one or more secondary data volumes to be attached when you provision the instance. Click Create in the Data volumes section to open the side panel where you can define the volume.
    Specify a unique, meaningful name. The same specifications apply as for the boot volume.
    You can toggle the auto-delete option on for the data volume. If it is enabled, then the volume is deleted when the instance is deleted. If it is disabled, then the volume persists after the instance is deleted.
    You can specify optional user tags and access management tags to associate with this volume. For more information about organizing resources with user tags, see Working with tags.
    You can select the encryption type. Provider-managed encryption is enabled by default on all volumes. You can also choose to create an envelop encryption with your own root keys that are created and maintained in Key Management Services.
    You can select the Storage profile that best suits your needs for capacity and IOPS. For more information, see Create and attach a Block Storage volume when you create an instance.
    Virtual private cloud Specify the IBM Cloud VPC where you want to create your instance. You can use the default VPC, another existing VPC, or you can create a VPC. To create a VPC, click New VPC.
    Add to cluster network Beta If you select the H100 GPU profile, gx3d-160x1792x8h100, you see the option to Add to cluster network. You can set Add to cluster network to on to enable the virtual server to access the power of a high-performance network that supports Remote Direct Memory Access (RDMA). When Add to cluster network is set to on and a cluster network is available, the IBM Cloud console includes default selections for configuring the virtual server for the cluster network. If no cluster network is available, you can click Create cluster network. When a cluster network is selected, only the VPC where the cluster network is provisioned displays in the Virtual private cloud drop-down menu. For more information, see About cluster networks.
    Network interfaces By default the virtual server instance is created with a single primary network interface. You can click the Edit icon Edit icon to edit the details of the network interface, for example, the subnet or security group that's associated with the interface. To include extra secondary network interfaces, click Create. You can create and assign up to 15 network interfaces for your virtual server instance, depending on the vCPU count that is included in the instance profile. For more information, see About network interfaces.
    With the virtual network interface feature, you can select the type of network interface that you want to use. You can select the new option Network attachment with a virtual network interface or the legacy option Instance network interface. Whichever type of network interface option that you select when you provision the virtual server persists through the lifecycle of the virtual server. You can click Attach to create a network attachment with an existing virtual network interface. For more information, see About virtual network interfaces.

  5. For Advanced options, you can choose to complete more instance configurations.

    Trusted profile (optional) If you enable the metadata service, you can select a trusted profile and link it to this instance. Click Select a trusted profile. In the side panel, select a trusted profile and click Select trusted profile to link it to the instance. A message displays if none exist or if you don't have access to link it. For more information, see Create a trusted profile. For more information about acquiring access, see IAM authorizations for linking trusted profiles.
    Add to dedicated host This selection is disabled by default. To create the virtual server instance in a single-tenant space, click the toggle to enable the dedicated host. To provision a dedicated instance, you must have a dedicated host available or create one.
    Add to placement group Placement groups are disabled by default. Click the toggle to enable placement groups. Then, select or create a placement group for the instance. If you add a placement group, the instance is placed according to the placement group policy. For more information, see About placement groups.
    Add to reservation If you have an active reservation, click the toggle to add the virtual server instance to that reservation. For more information, see About Reservations for VPC.
    Host failure auto restart This setting is enabled by default. To disable host failure auto restart, click the toggle. For more information, see Host failure recovery policies.

  6. Click Create virtual server instance when you are ready to provision.

Next steps after an instance is created in the UI

After the instance is created, you need to associate a floating IP address to the instance. Then, you can connect to your instance. For more information, see Connecting to your Linux instance, Connecting to your Windows instance, or Connecting to your z/OS instance.

If you have an existing instance with a floating IP address, it isn't necessary to assign a second floating IP to another instance. You can connect to the first instance with a floating IP, then SSH to the second instance by using the private subnet IP address that is automatically assigned to it.

Creating a virtual server instance by using the CLI

You can create instances by using the command-line interface (CLI). If you would like to use user tags or access management tags to manage your resources, see Working with tags.

IBM Cloud CLI is not supported on LinuxONE (s390x processor architecture). However, you can install the CLI on another supported platform and use it with LinuxONE (s390x processor architecture) virtual server instances.

  8. List the available boot volumes for creating your instance. If you are creating an instance from an image, skip this step To create an instance from an existing volume, you must use a volume that is compatible with the instance options chosen previously. A compatible volume is in the same zone as the instance that is being provisioned, is unattached, and has an OS compatible with the profile that is selected in step 5. Use the volumes subcommand to see the compatible volumes. For example, to see unattached volumes with an x64 operating system architecture in us-south-1:

    ibmcloud is volumes --attachment-state unattached --operating-system-architecture amd64 --zone us-south-1

  9. You can optionally create a boot volume from a bootable snapshot and use that for your image. To list all snapshots for a volume, see View all snapshots that were created from the Block Storage for VPC volume. New If you plan to use a snapshot from another account, make sure that the right IAM authorizations are in place first. Then, contact the snapshot's owner for the CRN of the snapshot.

  10. List the available SSH keys that you can associate with your instance.

Creating an instance by using the CLI

Use the following information to create an instance with the CLI.

Provision from a stock or custom image

After you know the needed values, use them to run the ibmcloud is instance-create command. You also need to specify a unique name for the instance.

Use the following steps to create a basic virtual server instance from a stock image by using the CLI. By default, a boot volume is attached to the instance when the instance is created. For most virtual server instances, the default boot volume size is 100 GB. The default boot volume size for a z/OS virtual server instance is 250 GB.

  1. Create an instance by using the following command.

    ibmcloud is instance-create \
    INSTANCE_NAME \
    VPC \
    ZONE_NAME \
    PROFILE_NAME \
    SUBNET \
    --image IMAGE \
    --keys KEYS \

    For example, the following instance-create command uses the sample values that are found in the Gathering information section.

    ibmcloud is instance-create \
    my-instance \
    r006-35b9cf35-616e-462e-a145-cf8db4062fcf \

Create an instance with secure boot

Select availability

Confidential computing with Intel SGX for VPC is available only in the Dallas (us-south) and Frankfurt (eu-de) regions.

After you know the needed values, use them to run the ibmcloud is instance-create command. You also need to specify a unique name for the instance.

For enable-secure-boot, you need to specify either true or false. The default value is false.

Use the following steps to create a basic virtual server instance that enables secure boot.

Create an instance using the following command.

   ibmcloud is instance-create \
       INSTANCE_NAME \
       VPC \
       ZONE_NAME \
       PROFILE_NAME \
       SUBNET \
       --image IMAGE \
       --enable-secure-boot true \
       --keys KEYS \

For example, the following instance-create command uses the sample values that are found in the Gathering information section.

   ibmcloud is instance-create \
       my-instance \
       r006-35b9cf35-616e-462e-a145-cf8db4062fcf \

Next steps after an instance is created from the CLI

A series of emails is sent to your administrator: Acknowledgment of the virtual server instance order, order approval and processing, and a message that the instance is created.

If you choose a GPU profile, see Managing GPUs.

After the instance is created, associate a floating IP address to the instance. Then, you can connect to your instance. For more information, see Connecting to your Linux instance or Connecting to your Windows instance.

Creating a virtual server instance by using the API

You can create instances by using the API.

Before you begin

Make sure that you have the required access. To call these methods, you must be assigned one or more IAM access roles that include the following actions, depending on any listed conditions. You can check your access by going to the Users page of Cloud Identity and Access Management dashboard.

Gathering information to create an instance by using the API

Before you can create an instance, you need to know the details about the instance, such as the instance profile or the image that you want to use. Gather information by making the following API calls:

Required instance details api
Instance details Listing options API spec documentation
Image GET /images List all images
Profile GET /instance/profiles List all instance profiles
Key GET /keys List all keys
VPC GET /vpcs List all VPCs
Subnet GET /subnets List all subnets
Zone GET /regions/<region>/zones List all zones in a region
Placement groups GET /placement_groups List all placement groups

If you plan to use a snapshot from another account, make sure that the right IAM authorizations are in place first. Then, contact the snapshot's owner for the CRN of the snapshot.

Creating an instance by using the API

After you retrieved the information that you need, you can run the POST /instances method to create an instance.

Provision an instance from a stock or custom image by using the API

You can provision an instance with a stock or custom image by specifying the image's id subproperty as the value of the image property.

   curl -X POST "$vpc_api_endpoint/v1/instances?version=$api_version&generation=2" \
     -H "Authorization:$iam_token" \
     -d '{
           "name": "my-instance",

             "id": "'$image_id'"
            }
           }'

Provision an instance from a private catalog image by using the API

You can provision an instance with a private catalog image by specifying the image's offering_crn or the version_crn subproperty as the value of the catalog_offering property.

  • Create an instance by using a private catalog image from the latest version of a catalog product offering.

    curl -X POST "$vpc_api_endpoint/v1/instances?version=$api_version&generation=2" \
  -H "Authorization:$iam_token" \
  -d '{
        "name": "my-instance",
        "zone": {
          "name": "us-south-3"
        },
        "vpc": {
          "id": "'$vpc'"
        },
        "primary_network_interface": {
          "subnet": {
            "id": "'$subnet'"
          }

          "offering": {
            "crn": "'$offering_crn'"
         }
        }'

  • Create an instance by using a private catalog image from a specific version of a catalog product offering.

    curl -X POST "$vpc_api_endpoint/v1/instances?version=$api_version&generation=2" \
  -H "Authorization:$iam_token" \
  -d '{
        "name": "my-instance",

            "crn": "'$version_crn'"
         }
        }'

Provision from an existing volume

Reusing an existing, bootable volume is faster than creating a new volume from a snapshot or an image.

You can provision an instance with an existing volume by specifying the existing volume's id or crn subproperty as the value of the boot_volume_attachment property.

The existing, bootable volume must be an unattached bootable volume that has the same operating system and architecture as the instance profile. Use the list volumes filter and reference the attachment_state property and operating_system property to view a volume's eligibility.

For example, to see unattached volumes in us-south-1 with an x86 operating system.

curl -X GET "$vpc_api_endpoint/v1/volumes?version=2023-02-08&generation=2?attachment_state=unattached&zone.name=us-south-1&operating_system.architecture=amd64"
-H "Authorization: Bearer $iam_token"

By default, a boot volume that is created as part of provisioning a virtual server instance is deleted when the instance is deleted. You can change this behavior by setting the delete_volume_on_instance_delete property to false when you create the instance or update the boot volume attachment.

Use the POST /instances method to create an instance with the information you gathered. The following call is an example of provisioning an instance by using an existing boot volume.

curl -X POST "$vpc_api_endpoint/v1/instances?version=2023-02-08&generation=2"
-H "Authorization: Bearer $iam_token"
-d '{
  "boot_volume_attachment": {
    "volume": {

}'

For more information, see Create an instance.

Restore a boot volume from a snapshot and use it to provision a new instance

You can restore a boot volume from a bootable snapshot and then use that boot volume when you provision an instance. The bootable snapshot must have the same operating system and architecture as the instance profile.

In the POST /instances request, specify the boot_volume_attachment property and the bootable snapshot ID in the source_snapshot subproperty. Alternatively, you can also use the name or the CRN of the snapshot. See the following example.

curl -X POST \
"$vpc_api_endpoint/v1/instances?version=2023-03-07&generation=2" \
-H "Authorization: $iam_token" \
-H "Content-Type: application/json" \
-d '{
      "boot_volume_attachment": {
        "delete_volume_on_instance_delete": true,
        "volume": {
            "profile": {
                "name": "general-purpose"
            },
            "source_snapshot": {
                "id": "eb373975-4171-4d91-81d2-c49efb033753"
            }
        }
     },
     .
     .
     .
  }'

Creating virtual server instances by using Terraform

You can create instances by using Terraform. If you would like to use user tags or access management tags to manage your resources, see Working with tags.

Before you begin

Make sure that you set up Terraform for VPC.

Creating a private catalog

This step is optional. If you plan to share images from a private catalog, the private catalog must be created first. If you select a catalog image that belongs to a different account, review Using cross-account image references in a private catalog in Terraform for more considerations and limitations. To create a private catalog, see the tutorial Onboarding a virtual server image with Terraform.

Gathering information to create an instance by using Terraform

Ready to create an instance? Before you can run the ibm_is_instance command, you need to know the details about the instance, such as what profile or image that you want to use.

Gather the following information by using DataSource command.

  1. Gather instance profile details. Run the following command for the profile that you select. See x86 instance profiles for a list of available profiles. For more information, see the Terraform documentation on ibm_is_instance_profiles. Use an instance profile by referring to the instance profile data source. For more information, see the Terraform documentation on ibm_is_instance_profile.

    data "ibm_is_instance_profile" "example_profile" {
   name = "bx2-2x8"
}

  2. List the available images for creating your instance. The command depends on what image that you want to use. You can use a stock image, a custom image from your account, or an image that was shared with your account from a private catalog. For more information, see the Terraform documentation on ibm_is_image. If you plan to use an image that was shared from a private catalog, see the Terraform documentation on ibm_cm_version or ibm_cm_offering_instance.

    • Select a stock image or custom image from your account for your instance.
    data "ibm_is_image" "example_image" {
   name = "ibm-centos-7-6-minimal-amd64-2"
}

    If you select a catalog image that belongs to a different account, you have more considerations and limitations to review. See Using cross-account image references in a private catalog in Terraform.

    • To list all available private catalog image offerings, run the following command.

      data "ibm_is_images" "example_images" {
   catalog_managed = true
 }

  3. Create a VPC resource or use an existing VPC by referring to the VPC data source. For more information, see the Terraform documentation on ibm_is_vpc.

    resource "ibm_is_vpc" "example_vpc" {
   name = "example-vpc"
}

  4. Create a subnet resource or use an existing subnet by referring to the subnet data source. For more information, see the Terraform documentation on ibm_is_subnet.

    resource "ibm_is_subnet" "example_subnet" {
   name            = "example-subnet"
   vpc             = ibm_is_vpc.example_vpc.id
   zone            = "us-south-1"
   ipv4_cidr_block = "10.240.0.0/24"
}

  5. Create a ssh-key resource or use an existing ssh-key by referring to the ssh-key data source. For more information, see the Terraform documentation on ibm_is_ssh_keys.

    resource "ibm_is_ssh_key" "example_sshkey" {
   name       = "example-sshkey"
   type       = "rsa"
   public_key = "ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQCKVmnMOlHKcZK8tpt3MP1lqOLAcqcJzhsvJcjscgVERRN7/9484SOBJ3HSKxxNG5JN8owAjy5f9yYwcUg+JaUVuytn5Pv3aeYROHGGg+5G346xaq3DAwX6Y5ykr2fvjObgncQBnuU5KHWCECO/4h8uWuwh/kfniXPVjFToc+gnkqA+3RKpAecZhFXwfalQ9mMuYGFxn+fwn8cYEApsJbsEmb0iJwPiZ5hjFC8wREuiTlhPHDgkBLOiycd20op2nXzDbHfCHInquEe/gYxEitALONxm0swBOwJZwlTDOB7C6y2dzlrtxr1L59m7pCkWI4EtTRLvleehBoj3u7jB4usR"
}

    SSH keys can be either RSA or ED25519. You can generate new RSA key pairs by using the UI. Pre-existing RSA and ED25519 SSH keys can be uploaded. ED25519 can be used only if the operating system supports this key type. ED25519 can't be used with Windows or VMware images.

  6. Create a subnet_reserved_ip resource or use an existing subnet_reserved_ip by referring to the subnet_reserved_ip data source. For more information, see the Terraform documentation on ibm_is_subnet_reserved_ip

    resource "ibm_is_subnet_reserved_ip" "example_reserved_ip" {
   subnet    = ibm_is_subnet.example_subnet.id
   name      = "example-reserved-ip1"
   address   = "${replace(ibm_is_subnet.example_subnet.ipv4_cidr_block, "0/24", "13")}"
}

Creating an instance by using Terraform

Create the instance by using one of the following examples. For more information, see the Terraform documentation on ibm_is_instance.

Run one of the following Terraform commands based on the image that you plan to use.

  • Create an instance by using a stock image or custom image from your account for your instance.

    resource "ibm_is_instance" "example_instance" {
  name    = "example-instance-reserved-ip"
  image   = data.ibm_is_image.example_image.id
  profile = data.ibm_is_instance_profile.example_profile.name

  primary_network_interface {
    name   = "eth0"
    subnet = ibm_is_subnet.example_subnet.id
    primary_ip {
      reserved_ip = ibm_is_subnet_reserved_ip.example_reserved_ip.reserved_ip
    }
  }
  network_interfaces {
    name   = "eth1"
    subnet = ibm_is_subnet.example_subnet.id
    primary_ip {
      name = "example-reserved-ip1"
      auto_delete = true
      address = "${replace(ibm_is_subnet.example_subnet.ipv4_cidr_block, "0/24", "14")}"
    }
  }

  vpc  = ibm_is_vpc.example_vpc.id
  zone = "us-south-1"
  keys = [ibm_is_ssh_key.example_sshkey.id]
}

  • Create an instance that uses a private catalog-managed image.

    resource "ibm_is_instance" "example_instance" {
  name    = "example-instance-reserved-ip"
  image   = data.ibm_is_image.example_image.id
  profile = data.ibm_is_instance_profile.example_profile.name

  primary_network_interface {
    name   = "eth0"
    subnet = ibm_is_subnet.example_subnet.id
    primary_ip {
      reserved_ip = ibm_is_subnet_reserved_ip.example_reserved_ip.reserved_ip
    }
  }
  network_interfaces {
    name   = "eth1"
    subnet = ibm_is_subnet.example_subnet.id
    primary_ip {
      name = "example-reserved-ip1"
      auto_delete = true
      address = "${replace(ibm_is_subnet.example_subnet.ipv4_cidr_block, "0/24", "14")}"
    }
  }

  vpc  = ibm_is_vpc.example_vpc.id
  zone = "us-south-1"
  keys = [ibm_is_ssh_key.example_sshkey.id]
}
