Introduction to Instance Management

Instance Management

There are two interfaces available for managing instances.  The first is in the Tenant panel, which will be the most commonly used of the two.  The second, an administrative view, provides a global view of the environment.  Instances can only be created within the Tenant panel, since every instance is associated explicitly with a single tenant.

To launch an instance, click the Tenant panel and select your tenant using the drop-down menu.  You will see an entry for each tenant of which you are a member.  Thus, if an administrator is launching instances on behalf of a tenant, they must first add themselves as a member of the tenant.  Once you are operating within the desired tenant, click Images & Snapshots.

The Images & Snapshots page will display the catalog of images available with which to launch an instance.  We preload several reference images based on popular Linux distributions.  Additional images can be loaded or converted as requested.  Each entry in the image catalog has a corresponding Launch button. Select the image of your choice and click Launch.

After clicking the Launch button, you will be prompted for the following information:

  • Instance Name: An arbitrary name for your instance. Uniqueness is not required but is recommended.  Best practices for naming are similar to that of DNS entries.

  • User Data (optional): Used to pass metadata between the orchestration system and your instance.  It is most commonly used in conjunction with Cloud Init, which is installed on all of our reference images by default.  More information about the function and purpose of the metadata service, see the Metadata API Reference. Our metadata API service is compatible with AWS.

  • Flavor: The virtual hardware resources allocated to this instance.  Flavors are also referred to as instance types.  They can be managed by administrators via the Admin panel.

  • Keypair (optional): An SSH public key to automatically place onto the instance upon launch.  SSH keys are managed via the Access & Security tab, where they can be uploaded or generated.  This field will be empty unless one or more keys have been added to the tenant.

  • Instance Count: We support bulk launching of instances.  Enter the number of instances you would like to launch with this singular request.
  • Security Groups: Firewall rules which control access to your instance.  By default, all access is denied unless an explicit allow rule is created.  Security groups can be managed via the Access & Security tab.

Once this data has been entered, click the Launch Instance button to create your new instance.  You will be returned to the Instances & Volumes page where you will see the build status of your new instance.
