Networking

Networking¶

Untuk menggunakan informasi dalam bagian ini, Anda harus memiliki pemahaman umum OpenStack Networking, OpenStack Compute, dan integrasi antara keduanya. Anda juga harus memiliki akses ke sebuah plug-in yang mengimplementasikan Networking API v2.0.

Atur variabel lingkungan¶

Pastikan bahwa Anda mengatur variabel lingkungan yang relevan.

Sebagai contoh, lihat file shell contoh yang menetapkan variabel tersebut untuk mendapatkan mandat (credential):

export OS_USERNAME="admin"
export OS_PASSWORD="password"
export OS_TENANT_NAME="admin"
export OS_AUTH_URL="http://IPADDRESS/v2.0"

Dapatkan kredensial¶

Contoh pada bagian ini menggunakan metode get_credentials:

def get_credentials():
    d = {}
    d['username'] = os.environ['OS_USERNAME']
    d['password'] = os.environ['OS_PASSWORD']
    d['auth_url'] = os.environ['OS_AUTH_URL']
    d['tenant_name'] = os.environ['OS_TENANT_NAME']
    return d

Kode ini berada di file credentials.py, yang semua sampel impor.

Gunakan metode ``get_credentials () `` untuk mengisi dan mendapatkan kamus (dictionary):

credentials = get_credentials()

Dapatkan Nova kredensial¶

Contoh pada bagian ini menggunakan metode get_nova_credentials

def get_nova_credentials():
    d = {}
    d['username'] = os.environ['OS_USERNAME']
    d['api_key'] = os.environ['OS_PASSWORD']
    d['auth_url'] = os.environ['OS_AUTH_URL']
    d['project_id'] = os.environ['OS_TENANT_NAME']
    return d

Kode ini berada di file credentials.py, yang semua sampel impor.

Gunakan metode get_nova_credentials() untuk mengisi dan mendapatkan kamus (dictionary):

nova_credentials = get_nova_credentials()

Cetak nilai¶

Contoh pada bagian ini menggunakan metode print_values dan print_values_server`:

def print_values(val, type):
    if type == 'ports':
        val_list = val['ports']
    if type == 'networks':
        val_list = val['networks']
    if type == 'routers':
        val_list = val['routers']
    for p in val_list:
        for k, v in p.items():
            print("%s : %s" % (k, v))
        print('\n')


def print_values_server(val, server_id, type):
    if type == 'ports':
        val_list = val['ports']

    if type == 'networks':
        val_list = val['networks']
    for p in val_list:
        bool = False
        for k, v in p.items():
            if k == 'device_id' and v == server_id:
                bool = True
        if bool:
            for k, v in p.items():
                print("%s : %s" % (k, v))
            print('\n')

Kode ini berada di file utils.py, yang semua sampel impor.

Buat jaringan (network)¶

Program berikut membuat jaringan:

#!/usr/bin/env python
from neutronclient.v2_0 import client
from credentials import get_credentials

network_name = 'sample_network'
credentials = get_credentials()
neutron = client.Client(**credentials)
try:
    body_sample = {'network': {'name': network_name,
                   'admin_state_up': True}}

    netw = neutron.create_network(body=body_sample)
    net_dict = netw['network']
    network_id = net_dict['id']
    print('Network %s created' % network_id)

    body_create_subnet = {'subnets': [{'cidr': '192.168.199.0/24',
                          'ip_version': 4, 'network_id': network_id}]}

    subnet = neutron.create_subnet(body=body_create_subnet)
    print('Created subnet %s' % subnet)
finally:
    print("Execution completed")
