All the plugins should subclass EnvBuilderPlugin from "model.py".
The EnvBuilderPlugin is a template class with a template algorithm:
def __init__(self, ):
pass
@abstractmethod
def clean(self):
#clean Environment before goes further.
@abstractmethod
def install(self):
#install network virtualization software from source code.
@abstractmethod
def load_drivers(self):
#loads drivers for network card.
@abstractmethod
def create_brs(self):
#creates virtual switches.
@abstractmethod
def config_br_ports(self):
#config the vlan property for vswitch ports.
def create_vms(self):
#create vms
def wait_vms(self):
#wait vm to boot up and config vm for ips and other configurations.
def check_vm_connectivity(self):
#check if the vms correctly setup the control panel ips.
def build(self, cfg_intent):
self.host_cfg = cfg_intent #please retrieve options from self.host_cfg for your use in other methods.
self.clean()
self.download_and_compile()
self.load_drivers()
self.create_brs()
self.create_vms()
self.wait_vms()
self.config_tap_vlans()
self.check_vm_connectivity()
You should implements the abstract methods left empty, however you can make some methods do nothing to skip steps..
The plugin receives a "cfg_intent", The "cfg_intent" is a python dict parsed from a env-build configuration file.
It contains the detail configurations for the plugin to build a "virtual network" for testing.
There are some example json config files for building different type of "virtual network" under "etc/vstf/env" that you can refer to.
Before you creates a new plugin, you should make sure you understand these json config file properly.
