Configuring Instances in Contrail Insights

 

This section describes the Instances detail screen and how to configure instances for virtual or physical servers using Contrail Command.

Note

For Contrail Insights releases prior to 3.2.6: In order to view and configure instances, your Contrail Insights license subscription must be active.

Instance Details Overview

Table 1 provides descriptions for the instances column headers.

Table 1: Instance Details Headers and Columns

Header

Description

Status

The lights indicate the provisioning status of an instance and has multiple states: Red indicates an alert state, green indicates a normal state, yellow indicates warning state and grey for other states. Spinning circle means “in progress” and solid dot means “static.” If status information is missing (no-data), this field is empty.

Name

Shows the name of each instance.

State

Shows the current state of the instance. Power On: Active means the instance is running.

Server Type

Indicates which server type is in use, such as Baremetal Server. No LCM (lifecycle management) means that Contrail Command is not managing the server.

Networks

Displays the virtual network (VLAN) associated with the instance.

IP Addresses

Shows the IP address of the server.

Console

Indicates if a console port is available for the server.

Creating Instances

A virtual network in the Contrail environment allows hosts in the same network to communicate with each other. This is similar to assigning a VLAN to each host so that hosts on the same VLAN can reach each other. An instance then matches the virtual network to devices and their interfaces, as shown in Figure 1.

To configure an instance to map a virtual network to devices and interfaces:

  1. Select Infrastructure > Workloads > Instances. All virtual machine instances and baremetal server instances created appear on the Instances screen.
    Figure 1: Workloads > Instances
    Workloads > Instances
  2. Click Create, as shown in Figure 1, to add a new instance.Note

    (Optional) Click the ellipsis (…) to edit or remove an instance.

  3. Select Server Type, which is either physical or virtual.
    1. When either Virtual Machine or New Baremetal Server are selected, complete the following fields, described in Table 2, to define an instance for the selected server:

      Table 2: Create Instance Fields—Virtual Machine or New Baremetal Server

      Field

      Description

      Instance Name

      Enter a name for this instance you are creating.

      Select Boot Source

      Select an image or clone from the list as your boot source.

      Select Image

      Select the software image from the list.

      Select Flavor

      Select the default configurations for virtual machines.

      Available Networks

      Network resources that are currently available.

      Allocated Networks

      Network resources that can be allocated according to the demands of workloads.

      Select SSH Key

      Select an SSH key credential.

      Availability Zone

      Select an availability zone. An availability zone groups network nodes that run services like DHCP, L3, FW, and others. This allows you to associate an availability zone with their resources so that the resources get high availability.

      Count

      Select a number from 1 - 10, which represents the number of instances to launch.

    1. When Existing Baremetal Server is selected, complete the following fields, described in Table 3, to define an instance for the selected server:

      Table 3: Create Instance Fields—Existing Baremetal Server

      Field

      Description

      Create Existing Baremetal Server

      Instance Name

      Enter a name for instance you are creating.

      Baremetal Node

      Select the name of the server.

      Associate interfaces

      Interface

      Name of the physical interface and MAC address for the server.

      IP Address

      IP address of the server’s physical interface.

      VLAN ID

      Identifier for the VLAN.

      Virtual Network

      Name of the virtual network to be mapped to this instance.

      Select Security Groups

      Defines which devices are in a security group.

  4. Click Create to finish creating the instance.
  5. To add other instances, click Create, as shown in Figure 1.
