Issues in launching Iperf NSD docker tutorial, Errors: invalid CIDR address, and Image with name or id [iperfserver:latest] not found

[mehdishar]

I installed Openbaton on Linux Ubuntu 16.04 using the bootstrap procedure here. I start NFVO service on each startup of my Linux (by adding the line "sudo systemctl start openbaton-nfvo.service" to /etc/rc.local). I can then access Openbaton dashboard GUI by entering http://localhost:8080 in my browser (it redirects me to https://localhost:8443/#/main).

My goal is to run Iperf NSD tutorial in two different docker containers. So, I built client and server docker files as in the tutorial. When I run "$ sudo docker images" command, I see client and server images in the output:

As a requirement, for Docker VM driver, I ran it according to this doc; Specifically, I ran "$ sudo ./docker-driver -conf config.toml" with the following config :

"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
type = "docker"
workers = 5
username = "openbaton-manager-user"
password = "openbaton"
logLevel = "DEBUG"
brokerIp = "localhost"
brokerPort = 5672
"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""

The driver run-time shows this :

As another requirement, I downloaded and ran Docker VNFM according to this doc. This is my config :

"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
type = "docker"
endpoint = "docker"
allocate = true
workers = 1
description = "The Vnfm description"

logLevel = "INFO"
brokerIp = "localhost"
brokerPort = 5672
"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""

After I run "$ sudo ./docker-vnfm -conf config.toml ", this is the run-time output:

In Openbaton dashboard => Catalogue => VNF Managers, I see the following list:

"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""

In the dashboard Installed drivers page, I see this list:

Then, I registered the Docker Engine as a PoP via this setup:

"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
{
"name": "vim-instance",
"authUrl": "unix:///var/run/docker.sock",

}
}
"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""

Then, I tried to launch the following NSD json from the tutorial :

"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""

}
"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""

However, in NS Records page, I observe the following errors (invalid CIDR address):

"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""

"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""

Then, I tried to use another virtual link to replace "new-network". Looking at my Vim-instance in PoP information page, I see the following list of Networks:

"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""

"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""

As a trial, I replaced "new-network" with "host" in the NSD json and launched it again. However, I see the state in NS records in NULL. Clicking on one of VNF records there, I see:

Can you please help me to find the cause of the issue and how to resolve it ? and what is your idea about the connection point or virtual links should I set in my NSD json for this iperf docker tutorial ? Any kind of help is appreciated.

Thank you in advance,
Mehdi
