'''grrrit-wm''' is an IRC bot that listens to events from [[Gerrit]] and reports them on various IRC channels; it replaces gerrit-wm. 

Which repo changes report to which channels can be configured in <code>config.yaml</code> [https://phabricator.wikimedia.org/diffusion/TGRT/browse/master/config.yaml;1882bdfc5aa44ee4ad4abdb8b7ac162f5858f62f? config.yaml]; it defaults to #wikimedia-dev, see [[mw:MediaWiki on IRC]].

== Running it ==

It runs in a Docker container in our new [[Kubernetes]] cluster under the tools project in labs. It uses one of the base containers that tool labs provides (docker-registry.tools.wmflabs.org/toollabs-nodejs-base:latest). You can see the YAML file used as the kubernetes deployment definition in <code>kubernetes-deployment.yaml</code> in the repository. If you want to start the bot entirely from scratch, then just doing <code>kubectl apply -f kubernetes-deployment.yaml</code> should work.

== Config changes ==

To add more repo -> channel mappings, edit <code>config.yaml</code>. The repo names can be matched using regexen. The tool needs to be restarted for the changes to take effect - see [[#Deploying|the deploying]] and [[#Restarting the bot|restarting]] sections for more.

== Building/Deploying ==

==== Log files ====
<syntaxhighlight lang="bash">
ssh tools-login.wmflabs.org
become lolrrit-wm
kubectl get pods
kubectl logs grrrit-otnlc   # use actual pod name from previous command
</syntaxhighlight>

===== Deploying or restarting =====

<syntaxhighlight lang="shell-session">
$ ssh tools-login.wmflabs.org
$ become lolrrit-wm
# cd into lolrrit-wm and change repository to deploy (e.g. git pull)
$ kubectl get pods
NAME                          READY     STATUS    RESTARTS   AGE
grrrit-wm-230500525-qk7fl     1/1       Running   0          2m
lolrrit-wm-3433923449-x40eu   1/1       Running   0          4d
$ kubectl delete pod grrrit-wm-230500525-qk7fl # use actual pod name from previous command
</syntaxhighlight>

'''Temporarily Stopping'''
You can just [http://kubernetes.io/docs/user-guide/kubectl/kubectl_scale/|scale the deployment] to run 0 instances.

<syntaxhighlight lang="shell-session">
$ kubectl scale --replicas=0 deployment/grrrit-wm
deployment "grrrit-wm" scaled
</syntaxhighlight>

'''Restarting after stopping'''

Just scale it back to 1 instance.
<syntaxhighlight lang="shell-session">
$ kubectl scale --replicas=1 deployment/grrrit-wm
deployment "grrrit-wm" scaled
</syntaxhighlight>

== Code == 

The code is hosted on Gerrit, under <code>labs/tools/grrrit</code> [https://phabricator.wikimedia.org/diffusion/TGRT/].

== Historical ==
* It first used to run on the gridengine, and received gerrit changes via redis stream
* Then it ran on gridengine, but didn't use redis at all
* It was the first tool to be moved to kubernetes, using a custom docker image
* Now it just runs on the kubernetes cluster, without any custom docker images.

== npm 2 upgrade changes ==

cd ~/lol*

edit

.profile

add

source ~/.bashrc

at bottom of file.


Then edit

.npmrc

and add

prefix = /data/project/lolrrit-wm/.npm-packages

Then run

/usr/share/npm/bin/npm-cli.js install -g npm@2 // Change the 2 to the version you want.
