Host and Port Configuration

[thegorski]

Hello,

How do I figure out the correct host and port to use for the following steps? Thank you.

cd free5gmano-cli/nm
vim setting.py

Hi @cewuandy @tw0927041027 @Samcandy

It's really appreciated if you could shed some light for us.

I have the same concern with @thegorski , i'm not sure how to configure it.
Here is my pod info. Which mano/nfvo IP addresses should be use?

I try as below:
ubuntu@ubuntu-KVM:~/simpleexampleplugin$ cat config.yaml
allocate_file: "allocate/main.py"
deallocate_file: "deallocate/main.py"
nm_host: '192.168.254.210:8000'
nfvo_host: '192.168.254.208:8000'
subscription_host: '192.168.254.210:8082'

ubuntu@ubuntu-KVM:~$ cat free5gmano-cli/nm/settings.py
NM_HOST = '192.168.254.210'
NM_PORT = '30088'
NM_URL = 'http://{0}:{1}/'.format(NM_HOST, NM_PORT)

But it fail to run nmctl register
ubuntu@ubuntu-KVM:~$ nmctl register plugin kube5gnfvo -f simpleexampleplugin/

Hi @nmpvinh

Please change "NM_HOST" to your Kubernetes Master IP , and the "NM_PORT" use service/free5gmano NodePort type port "30088" , and try it again . Thank you .

Hi @yanyan8566

Can you please tell what is the host and port configuration if we are using openstack and tacker.
