LXC_BRIDGE="lxcbr0"
LXC_ADDR="10.0.3.1"
LXC_NETMASK="255.255.255.0"
LXC_NETWORK="10.0.3.0/24"

=Previous installation procedure (Juju server VM)=
This VM will receive commands from Juju client VM when doing manual testing, or directly from Rift.io Launchpad VM in OSM context. Juju charms will be deployed as containers in this VM.
 
1. Create a VM with Ubuntu 14.04 LTS and assign 4 vcpu, 4GB RAM and 40GB drive at least
 
2. Create user juju in sudo group
  sudo adduser juju
  usermod -a -G sudo juju


3. Change the default lxc networks, as in the lab setup the default lxc network (10.0.3.0/24) is already being used:
=Configuration=
  sudo apt-get install systemd-services lxc
*In the Juju client, edit '''/etc/squid-deb-proxy/mirror-dstdomain.acl''' to add the following lines:
# launchpad personal package archives (disabled by default)
ppa.launchpad.net
  private-ppa.launchpad.net


Edit /etc/default/lxc-net to change the lxc network to 10.1.3.0/24:
*In the Juju client, restart squid-deb-proxy:
  LXC_BRIDGE="lxcbr0"
  sudo service squid-deb-proxy restart
LXC_ADDR="10.1.3.1"
LXC_NETMASK="255.255.255.0"
LXC_NETWORK="10.1.3.0/24"
LXC_DHCP_RANGE="10.1.3.2,10.1.3.254"


4. Configure the VM to access the management networks of openvim and openstack. This is a requirement for juju to be able to connect to the deployed VNFs.
*In the Juju client, create file '''${HOME}/.juju/environments.yaml''' using the appropriate IP address for the bootstrap host (Juju server's IP address) and for the squid proxy (either the IP address of the LXC bridge - 10.0.3.1 - in case of a single-VM installation, or the IP address of the Juju client in case server and client are running in different VMs).

VM creation

  • Juju Server and Client (single VM)
    • Minimum Requirements:
      • 4 vCPU
      • 4GB RAM
      • 40GB disk
  • Base image: ubuntu-14.04.4-server-amd64

In case you want to install them in separate VMs, the minimum requirements are:

  • Juju Server:
    • 4 vCPU
    • 4GB RAM
    • 40GB disk
  • Juju Client:
    • 2 vCPU
    • 2GB RAM
    • 20GB disk
  • Base image in both cases: ubuntu-14.04.4-server-amd64

Installing required packages and libraries

Install Juju Server

  • Create a user (e.g. user osm, pwd osm) and add it to the sudo group.
sudo adduser osm
usermod -a -G sudo osm
  • Install packages for Juju Server
sudo apt-get install systemd-services lxc ssh
  • If required, edit the file /etc/default/lxc-net to change the lxc network addressing. This is only needed if there is overlapping with other network interfaces used by the Juju Server.

For instance, in order to use the subnet 10.0.3.0/24, you could make the following configuration: 

LXC_BRIDGE="lxcbr0" 
LXC_ADDR="10.0.3.1"
LXC_NETMASK="255.255.255.0"
LXC_NETWORK="10.0.3.0/24"
LXC_DHCP_RANGE="10.0.3.2,10.0.3.254"
LXC_DHCP_MAX="253"

Install Juju Client

  • Install packages for Juju Client
sudo apt-get install software-properties-common
sudo add-apt-repository ppa:juju/stable
sudo apt-get update
sudo apt-get install juju juju-local juju-quickstart charm-tools squid-deb-proxy

Configuration

  • In the Juju client, edit /etc/squid-deb-proxy/mirror-dstdomain.acl to add the following lines:
# launchpad personal package archives (disabled by default)
ppa.launchpad.net
private-ppa.launchpad.net
  • In the Juju client, restart squid-deb-proxy:
sudo service squid-deb-proxy restart
  • In the Juju client, create file ${HOME}/.juju/environments.yaml using the appropriate IP address for the bootstrap host (Juju server's IP address) and for the squid proxy (either the IP address of the LXC bridge - 10.0.3.1 - in case of a single-VM installation, or the IP address of the Juju client in case server and client are running in different VMs).
