ImportError: No module named cabot-check-network

[nmarshall-cst]

I am using the docker image for Cabot and I am interested in extending some of the functionality with the cabot-check-network plugin. Is there documentation on how I can accomplish this? I have added this plugin to the $CABOT_PLUGINS_ENABLED envar, but I am receiving the error below. I have tried creating my own docker image where I RUN pip install --no-cache-dir --disable-pip-version-check https://github.com/cabotapp/cabot-check-network/archive/master.zip , but this didn't help. This may be my lack of python/django knowledge. I have searched all of the documentation and issues in the Cabot project, but falling short on how I should be enabling additional plugins. Thanks in advance!!

CABOT_PLUGINS_ENABLED: 'cabot_alert_hipchat,cabot_alert_twilio,cabot_alert_email,cabot_alert_slack,cabot-check-network'

Hello !

Same problem here, did you manage to get something working ? (I assume not)

Actually, Cabot gets a lack of documentation about Plugins (installation).
I've peeled the Wiki, but no trace about that...

If @JeanFred could guide us it'd be very cool 👌

Bye 👋

[nmarshall-cst]

@HorlogeSkynet I have not figured this out quite yet. I scoured the documentation as well, but could not find anything to point me in the right direction. I would be happy to PR the documentation updates if we find a fix for this.

[HorlogeSkynet]

Yeah same for me !

Nevertheless, I'm onto something, keep you posted 👌

[HorlogeSkynet]

Okay, this is a way to do it apparently :

1. git clone git@github.com:arachnys/cabot.git
2. cd cabot/
3. Add git to the Dockerfile dependencies, and add a new line : RUN git clone https://github.com/cabotapp/cabot-check-network.git && cd cabot-check-network/ && python setup.py install (because cabot_check_network is not present on PyPi repositories yet)
4. Tweak the conf/development.env file with your information
5. Adds the cabot_check_network plugin to conf/default.env
6. docker-compose build
7. docker-compose up

But it failed afterwards with :

Okay, I'm back 'cause I finally got it working. New procedure :

git clone git@github.com:arachnys/cabot.git
cd cabot/

Now tweak the conf/development.env file with your information, and once it's done run :

docker-compose build
docker-compose up

Now, if @JeanFred could explain how (if it's possible) we can add a plugin to existing Cabot containers, it'd be perfect !

Thanks @HorlogeSkynet. Works great.

+1 on the request for explanation on adding plugin to existing Cabot containers.
