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 config.yaml 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 kubernetes-deployment.yaml in the repository. If you want to start the bot entirely from scratch, then just doing kubectl apply -f kubernetes-deployment.yaml should work.

Config changes

To add more repo -> channel mappings, edit config.yaml. The repo names can be matched using regexen. The tool needs to be restarted for the changes to take effect - see the deploying and restarting sections for more.

Building/Deploying

Log files

ssh tools-login.wmflabs.org
become lolrrit-wm
kubectl get pods
kubectl logs grrrit-otnlc   # use actual pod name from previous command

Deploying or restarting

$ 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

Temporarily Stopping You can just the deployment to run 0 instances.

$ kubectl scale --replicas=0 deployment/grrrit-wm
deployment "grrrit-wm" scaled

Restarting after stopping

Just scale it back to 1 instance.

$ kubectl scale --replicas=1 deployment/grrrit-wm
deployment "grrrit-wm" scaled

Code

The code is hosted on Gerrit, under labs/tools/grrrit [1].

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.
