Ci::Connector

⚠️ The scripts in the bin folder are not included in the docker image, but released via a ConfigMap. After changing them, you need to run make release-notification to deploy your local version of the scripts, so be careful that your local version is up to date.

Usage

Using the docker image

Sample script

./main.rb

#!/usr/bin/env ruby

require "CI/connector"

conn = CI::Connector.from_env()
conn.on('github.pull_request') do |event|
  if event['action'] == 'closed'
    conn.logger.info "Close PR #{event['number']}"
  end
end

trap("TERM") { conn.stop }
trap("INT") { conn.stop }

Docker deployment

Minimal Dockerfile

./Dockerfile

FROM docker.k8s.jobteaser.net/coretech/ci-connector:<TAG>
COPY main.rb /usr/src/app/main.rb

export KAFKA_BROKERS=<kafka>
export KAFKA_CONSUMER_GROUP=<groupname>

docker run -d -e KAFKA_BROKERS -e KAFKA_CONSUMER_GROUP <image_name>
