Configure HUAWEI Cloud for Cloud Bursting

Create the necessary components in HUAWEI Cloud that are required for cloud bursting and then create a cloud bursting scenario.

Before you can begin creating the components necessary for cloud bursting, you must create and activate an HUAWEI Cloud account.

Obtain the HUAWEI Cloud Administrator Credentials

Get the credentials for the HUAWEI Cloud administrative user account so that you can later use this information to create a cloud account in Control.

You must already have signed up for an HUAWEI Cloud account.
When subscribing to HUAWEI Cloud, an administrative user account that has permissions for all system operations is automatically created. Use this user account to add an HUAWEI Cloud account to Control. Reset the password for this account when the password is unknown.
Note: Alternately, you can create a new user and give the user administrative privileges by setting its User Group to "admin".
  1. Login to the HUAWEI Cloud Console.
  2. Click Service List.

    HUAWEI Cloud Console

Check HUAWEI Cloud Account Service Quotas

View your account resource usage and limits.

Quotas are used to limit the number of resources available to users. It is important to ensure you are not exceeding your quota while setting up the resources for cloud bursting. If the existing resource quota cannot meet your service requirements, you can submit a work order to increase your quota. Once your application is approved, your resource quota is updated accordingly and you will be sent a notification.

  1. Login to the HUAWEI Cloud Console.
  2. Click Resources > My Quota.

    View Quotas

Installing and Configuring the PBS MoM on the VM

Install the PBS MoM on the virtual machine and configure the VM per your site's environment.

Log into the VM using the default user "root" and the .pem generated during the creation of the VM.

A startup script is provided during the creation of the bursting scenario. This script is ran after a cloud node is burst and is used to set up the system environment so that nodes burst in the cloud can communicate with the PBS Server. A service specifically designed for cloud instance initialization is cloud-init and is utilized by Control when booting cloud nodes, therefore it must be installed on the VM. For more information about installing cloud-init, refer to the Cloudinit Documentation.

  1. Login to the HUAWEI Cloud console.
  2. Click Service List.

    HUAWEI Cloud Console
    Figure 8. HUAWEI Cloud Console
  3. Under Computing, click Elastic Cloud Server.
  4. Copy the Public IP address (External IP) of the ECS.

    VM IP Address
    Figure 9. VM IP Address
  5. Login to your site's PBS Server.
  6. SSH into the VM using the default user "root", the .pem file you generated when creating the VM and the External IP assigned to the VM.
    ssh -i /path/my-key-pair.pem root@IPV4PublicIP
    where /path/my-key-pair.pem is the path to the .pem file downloaded while creating the virtual machine and IPV4PublicIP is the public IP address of the virtual machine.
  7. Copy the PBS Professional installation package to the VM.
  8. Using the PBS Professional Installation and Upgrade Guide, install and configure the PBS Professional MOM.
  9. Configure the VM for your site's environment such as mounting file systems, connecting it to the authentication service, installing any applications, etc.
  10. Install cloud-init.
  11. Connect the VM to your PBS Professional server and submit a job to ensure it is working as expected.

Create an OS Image

Create an image of the virtual machine configured per your site's requirements.

You must have already created a ECS (virtual machine), installed the PBS MoM on the ECS and configured it per your site's environment.

HUAWEI Cloud documentation can be found at Creating a Linux Private Image.

    The time required for creating an image varies depending on the image file size. Generally, it takes about 20 minutes to create an image. The image is successfully created when its image status changes to Normal.
    Note: Do not perform any operation on the selected ECS or its associated resources during image creation.
You can now delete the virtual machine so that you are no longer charged for it.

Create an HUAWEI Cloud Bursting Scenario

Create an HUAWEI Cloud bursting scenario so that PBS execution nodes can be burst in the cloud.

Open a browser window and login to the HUAWEI Cloud console. Open a second browser window and login to Control.

A startup script is provided during the creation of the bursting scenario. This script is ran after a cloud node is burst and is used to set up the system environment so that nodes burst in the cloud can communicate with the PBS Server. Use a cloud-init script for the startup script. For more information about writing cloud-init scripts, refer to the Cloudinit Documentation and Cloud Bursting Startup Script.

  1. Navigate to the Control browser window.
  2. Click the Cloud tab.
  3. Click Bursting from the Infrastructure menu located on the left-hand side of the web page.

    It is recommended to leave this disabled.
  27. For Cloud-init script, click Browse, browse for the startup script file and select it.
    This script will run after a cloud node is burst.
  28. Add public SSH keys for any users that you want to have access to the burst nodes:
    1. Login to the PBS Professional Server.
    2. Copy the public SSH key for the user.
      Public key files are usually stored in /.ssh in the user's home directory.

    It is expressed as an integer whose units are in seconds.

  30. For Tags, enter a key-value pair to add a label to the cloud node and press ENTER.
    A tag is a label that is assigned to a cloud node. Tags enable cloud nodes to be categorized in different ways, for example, by purpose, owner, or environment.
    The key-value pair must be entered as key:value. The key must be less than 36 characters and the value must be less than 43 characters. The length of both the key + value should be less than 80 characters. Valid values are alphanumeric, dash (-) and an underscore ( _ ).
