Hi, not a Python expert but cobbled this together. Maybe contains something useful.
It starts the cifs/nfs services.
called from shell
Code:
echo "Enable services..."
python3 "${bin}/truenas_services.py" --action "start"
truenas_services.py
Code:
import argparse
import sys
import requests
import json
import yaml
import os
import logging
import logging.config
from pathlib import Path
from requests.auth import HTTPBasicAuth
failure = False
script_folder = os.path.dirname(os.path.realpath(__file__))
log_config_path = os.path.abspath(os.path.join(script_folder, '..', 'bin_var', 'logging.yaml'))
config_path = os.path.abspath(os.path.join(script_folder, '..', 'bin_var', 'config_truenas_services.json'))
config = yaml.safe_load(open(log_config_path, 'r'))
logging.config.dictConfig(config)
logger = logging.getLogger()
with open(config_path) as json_data_file:
config = json.load(json_data_file)
# http://<host>/api/docs/

json_string = r'{"service": "' + service + r'","service-control": {"ha_propagate": false}}'
try:
resp = requests.post(api_call, json=json.loads(json_string), headers=headers)
if resp.status_code != 200:
logger.error('Action "{}" on host "{}" for service "{}" failed with error: {}'.format(action, host, service, resp.status_code))
failure = True
else:

parser = argparse.ArgumentParser()
parser.add_argument('-a', '--action', required=True, type=str)

action = args.action
for nas in config:

config_truenas_services.json
Code:

"skip": false
},

"host":"nas2",
"api_key":"<key2>",
"skip": false
}
}
logging.yaml. Filename is full path. If i remember correctly this was really necessary.
