Specify a network during instance build

code for creating a networking using code

Add the parameter network and send its name or id to attach the instance to:

testing_instance = conn.create_server(wait=True, auto_ip=True,
    name=instance_name,
    image=image_id,
    flavor=flavor_id,
    network=network_id)

Add the option Networks and send its id to attach the instance to:

opts := servers.CreateOpts {
    Name: instanceName,
    ImageRef: image.ID,
    FlavorRef: flavor.ID,
    SecurityGroups: []string{securityGroupName},
    UserData: []byte(userData),
    Networks: []servers.Network{servers.Network{UUID: networkID}},

}

testingInstance, _ = servers.Create(client, keypairs.CreateOptsExt {
    CreateOptsBuilder: opts,
    KeyName: keyPairName,
}).Extract()
