These instructions are oriented to install OSM Release THREE. This guide will be updated shortly to reflect the procedure for OSM Relase FOUR. Meanwhile you can refer to the main OSM Release FOUR Guide


Configure LXD

LXD setup

Install the lxd package

sudo apt-get update 
sudo apt-get install -y lxd newgrp lxd


Configure LXD with a bridge for networking

sudo lxd init

Although further customization is possible, these options for LXD bridge configuration will work:

  • Name of the storage backend to use (dir or zfs) [default=dir]
  • Would you like LXD to be available over the network (yes/no) [default=no]
  • Do you want to configure the LXD bridge (yes/no) [default=yes]?
  • Do you want to setup an IPv4 subnet? Yes
  • Default values apply for more questions questions
  • Do you want to setup an IPv6 subnet? No

Beware that, by default, LXD creates a bridge named lxdbr0.

Check MTU

Check the MTU of the LXD bridge (lxdbr0) and the MTU of the default interface. If they are different, change the default MTU of the containers. This might be required, for instance, when running OSM in a VM on some special conditions.

Note: In this example, we will assume that the default interface is ens3 and its MTU is 1446: 

lxc list # This will drive initialization of lxdbr0 
ip address show ens3 # In case ens3 is the default interface 
ip address show lxdbr0 
sudo lxc profile device set default eth0 mtu 1446 # Use the appropriate MTU value

Testing LXD

To test that your LXD installation is correct, try to deploy a container and run 'apt-get update' from inside: 

lxc launch ubuntu:16.04 test # Create a container based on Ubuntu 16.04 with name 'test'
lxc exec test bash                 # Access the container

root@test:~# apt-get update # Run command 'apt-get update' from inside the container </nowiki>
root@test:~# exit                  # Exit from the container

lxc stop test                          # Stop the container
lxc delete test                       # Delete the container

INSTALL OSM FROM SCRIPT

Download script, modify perms, and run install

wget https://osm-download.etsi.org/ftp/osm-3.0-three/install_osm.sh
chmod +x install_osm.sh
lxc list
./install_osm.sh --lxdimages -R ReleaseTHREE-hackfest2

Capture instructions at tail-end of installation and update .bashrc file

You might be interested in adding the following OSM client env variables to your .bashrc file: 

export OSM_HOSTNAME=10.126.86.221
export OSM_RO_HOSTNAME=10.126.86.42

Create the AWS vim

osm vim-create --name aws-site --user xxxxxxx --password yyyyyyyyy --auth_url https://aws.amazon.com --tenant admin --account_type aws --config '{region_name: us-west-2, flavor_info: {t2.nano: {cpus: 1, disk: 100, ram: 512}, t2.micro: {cpus: 1, disk: 100, ram: 1024}, t2.small: {cpus: 1, disk: 100, ram: 2048}, m1.small: {cpus: 1, disk: 160, ram: 1741}}}'


Verify vim creation

osm vim-list
lxc exec RO --env OPENMANO_TENANT=osm openmano datacenter-list

Check that route to reach juju controller is via VCA, and this was added properly

cat /etc/rc.local
route add -host 10.44.127.207 gw 10.126.86.216

(Where .207 is the juju controller IP, and gw IP is VCA IP (can get from lxc list VCA)

Then, remove any additional routes if needed.

Test Accessing the Console

Try visiting the console by accessing the private IP of the instance from another instance within the same subnet.

  • E.g. https:// 172.31.17.232:8443

You should see the OSM console log in screen. Log in with default credentials.

ONBOARD/CONFIGURE VNFs

Upload packages for vnf and ns

osm upload-package vnfpackage
osm upload-package nspackage

You can also do this from the UI by dragging and dropping the VNF FIRST and then the NS file

Log in to the UI, go to Catalog and confirm packages are onboarded in catalog and Instantiate

  • Go to Catalog and then click on Management in the NSD descriptor
  • Update the “VIM Network” with a reachable AWS subnet (I picked the same subnet in which my OSM instance resides)
  • Go to Launchpad --> Instantiate
  • Click next
  • Add an “Instance Name” and verify that the “VIM Network” name is the same as the one you updated in the NSD Descriptor

Verify successful launch

Once deployed, get the public IP address and try to ssh (you can also try to run from any Linux): 

ssh ubuntu@<IP>
Pwd: c0mpl3xp4ssw0rd
nslookup www.telefonica.com <IP>

Here the domain should be properly resolved by the deployed VNF.
