Configuration¶
The ncolony configuration is stored in a directory, conf
.
There is no default – this directory needs to be passed explicitly
to the ncolony server as well as to the control command.
The usual command to modify this configuration is
python -m ncolony ctl add
(although remove
is also useful, of course).
In order to modify a command, add should be called with the
same name.
NColony will automatically restart the command when its configuration
changes.
Examples¶
Running Sentry:
$ python -m ncolony ctl add sentry --cmd /myvenv/sentry \
--arg start --arg --config=/etc/sentry.conf
or
from ncolony import ctllib
ctllib.add(name='sentry', cmd='/myenv/sentry',
args=['start', '--config=/etc/sentry.conf'])
Running a Twisted demo server:
$ python -m ncolony ctl add demo-server --cmd /myvenv/twistd \
--arg --nodaemon --arg web
or
from ncolony import ctllib
ctllib.add(name='demo-server', cmd='/myenv/twistd',
args=['--nodaemon', 'web'])
Note the --nodaemon
: programs run by ncolony should not daemonize,
so that ncolony can properly monitor them.
