Unicycle (Three-Node Cluster) - Supported in the future release

Akraino Portal Operations

Login

Visit the portal URL http://REGIONAL_NODE_IP:8080/AECPortalMgmt/ where REGIONAL_NODE_IP is the Portal IP.

Use the following credentials:

  • Username: akadmin
  • Password: akraino

Upon successful login, the Akraino Portal home page will appear.

Build or Deploy an Edge Site

From the Portal home page:

  1. Select an Edge Site MTN1 (or MTN2) by clicking on the radio button in the GUI table displayed in the Home page. These are the two default sites available in the Seed code.
  2. For the selected Edge site, select a Blueprint (Rover or Unicycle) from the drop-down menu.
  3. Click on Upload button (in the Blueprint column), this will open a pop-up dialog
  4. Provide the edge site-specific details such as:
    1. Host IP address
    2. Host user
    3. Host password.

    4. Click on Browse button, select the input file for Blueprint - Rover (Single-Node Cluster). 
      The input file is a property file that stores information in key-value format.  Sample input file used for ‘Rover’ deploy: 

      Copy and paste the below contents in to a file, and save it as rover.txt. Use this file for uploading as mentioned in step 4.d above.

      Verify the configuration details as applicable to your environment. For more details refer to Appendix - Edge Site Configuration

Tempest Tests

Prerequisites

Specifics around OpenStack are beyond the scope of this guide.

  • Validate all OpenStack settings as needed.
  • Ensure all necessary OpenStack services are up and running for a particular site.
  • Use appropriate values for the OpenStack username, password, region, and desired timeout.      

Running Tempest

  • Navigate to ETE testing page using the left navigation menu in the portal.
  • Select a deployed edge site in the Run Tests page, by clicking the radio button in the GUI table displayed.  This will enable the "Run Tempest" button.
  • Click on "Run Tempest" to trigger the tempest test on the deployed edge site.
  • Test status shows "In Progress" upon successful invocation.
  • Test status gets updated to 'Complete', once the job gets completed.

Installing ONAP

Prerequisites

Specifics around ONAP are beyond the scope of this guide.

  • Verify that a VLAN is created and can be used for OpenStack tenant VM
    • The VLAN ID
    • An IP (or a range of IP) that can be accessed from this VLAN
    • Gateway, DNS, for the IP

  5. User will see the "file uploaded successfully" message in the sites column. Then, "Install ONAP" button gets enabled.
  6. Click "Install ONAP" to begin the installation.
  7. The ONAP status changes from ‘Not started’ to ‘In progress’ to ‘Complete’.
  8. ONAP VM will be created successfully after the job completes.  It may take several hours for ONAP to become operational.

Onboarding a Sample VNF

  1. Navigate to the Akraino Sites page via the left navigation menu.
  2. Select a deployed edge site in the GUI table displayed. The VNF Onboard button becomes enabled.
  3. Click VNF Onboard This will open a Pop up dialog.  Choose VNF as vCDN (Sample VNF) from the drop-down
  4. Verify all the default entries as applicable to your environment.
  5. Click Onboard to begin the sample VNF installation. This process may take few minutes to complete.
  6. The VNF Onboard status changes from ‘Not started’ to ‘In progress’ to ‘Complete’.

The Sample VNF creates an Apache Traffic Server cache instance and a Locust load generator client instance in the OpenStack environment for the selected site.  By default, the Sample VNF will create a heat stack name ats-demo.  The heat stack will contain two instances named ats-demo-client and ats-demo-server.  The default configuration of the server instance is to cache the Big Buck Bunny videos from the internet server and then serve the video to the client from its ramdisk. The heat stack will output the client and server URLs.  The client URL will display the Locust load generator dashboard.  The server URL will allow you to play the video in a browser.

OpenStack stack output show ats-demo --all

Create New Edge Site locations

The Akraino seed code comes with default two sites: MTN1, MTN2 representing two lab sites in Middletown, NJ. This step of connecting to the database and creating edge_site records are only required if the user wishes to deploy on other sites.

To deploy a Rover (Single-Node Cluster) Edge Node, perform the following steps:

  • Check if the Akraino (Docker Containers) packages are stood up.
  • Connect to PostgreSQL database providing the host IP (name).
jdbc:postgresql://<IP-address-of-DB-host>:6432/postgres
user name = admin
password = abc123
use ‘pgAdmin |||’ Postgres client tool or connect to Postgres DB using SQL interface  


  • Execute the following SQL insert, bearing in mind these value substitutions:
    • edge_site_id: Any unique increment value. This is usually 1 but does not have to be.
    • edge_site_name: Human-readable Edge Node name.
    • region_id: Edge Node region number. Use select * from akraino.Region; to determine the appropriate value. Observe the region number associations returned from the query: Use 1 for US East, 2 for US West, and so on.

> insert into akraino.edge_site(edge_site_id, edge_site_name, crt_login_id, crt_dt, upd_login_id, upd_dt, region_id)
  values( 1, 'Atlanta', user, now(), user, now(),1);

ONAP Configuration

This configuration file is written as a YAML dictionary named parameters.

This dictionary will be selectively inserted into the ONAP VM environment file, depending on overall configuration.
