Recently came across this scenario:
- I create a VM with
conn.compute.create_server(*args)and have the server object. The server is allocated an IP over `DHCP` - I want the IPv4 address of the machine.
Seems tough ? Finally found this one:
from openstack import connection
conn = connection.Connection(
auth_url=configs['auth']['OS_AUTH_URL'],
project_name=configs['auth']['OS_PROJECT_NAME'],
username=configs['auth']['OS_USERNAME'],
password=configs['auth']['OS_PASSWORD'],
project_domain_name=configs['auth']['OS_PROJECT_DOMAIN_NAME'],
user_domain_name=configs['auth']['OS_USER_DOMAIN_NAME']
)
# Define network, security_groups_list, user_data_file_opened
# An example network config is given below
network = {
"name": "personal_network",
"security_group":"open",
"subnet": {
"name": "personal_network_subnet",
"ip_version": "4",
"cidr": "10.10.60.0/24",
"dns_servers":["8.8.8.8","8.8.8.4"],
"gateway_ip": "10.10.60.1"
}
}
network_ = [x for x in conn.network.networks(name=network['name'])][0]
node = conn.compute.create_server(
name=server_name,
image_id=image.id,
flavor_id=flavor.id,
networks=[{"uuid": network_.id}],
key_name=keypair.name,
security_groups=security_groups_list,
user_data=user_data_file_opened
)
node_ = conn.compute.wait_for_server(node, wait=360)
node_ip = conn.compute.get_server(node.id).to_dict()['addresses'][network['name']][0]['addr']
print(f'New node ip is {node_ip}')
I have pasted the gist here, https://gist.github.com/tonythomas01/e7cecc6c1aaa4d4ca221487659ef9f40
Tell me how it goes, good luck.
