This repo was forked to add author and commit messsage informations to google chat cloud build notifier.
Original Doc is here
For this to work your pipeline must add this information to a firestore collection named after the cloud source repository and with key equal to short sha of commit.
gcloud auth login
gcloud auth configure-docker
docker build . -f=./googlechat/Dockerfile --tag=gcr.io/${PROJECT_ID}/scaiitec/googlechat:${TAG}
docker push gcr.io/${PROJECT_ID}/scaiitec/googlechat:${TAG}
The container is supposed to work as a cloud run service waiting for messages produced by cloud build. So you have to configure it following the instructions at the official documentation or use terraform as in be-ci-cd repo in partcular the notifier module.
