- Set otopi environment to enable machine dialect
DIALOG/dialect=str:machine- Spawn desired installer and pass stdin and stdout to parser
- Process all otopi events in the loop
import subprocess
import otopimdp as mdp
# 1. Set machine dialog option
with open("/etc/ovirt-hosted-engine-setup.env.d/mycustom.env") as fd:
fd.write(
'export environment="${environment} DIALOG/dialect=str:machine"\n'
)
# 2. Spawn installer
installer = subprocess.Popen(["hosted-engine", "--deploy"])
parser = mdp.MachineDialogParser(
input_=installer.stdout, output=installer.stdin
)
# 3. Process events
while True:
event = parser.next_event()
if event is None:
continue
event_type = event[mdp.TYPE_KEY]
if event_type == mdp.TERMINATE_EVENT:
break
event_name = event[mdp.ATTRIBUTES_KEY]['name']
if event_name == "OVEHOSTED_HOST_ID":
event[mdp.REPLY_KEY] = "1"
....
parser.send_response(event)toxNOTE: For testing purposes, the otopi package is being run from sources.
