Integrating Alertmanager with Jenkins

At the moment, we are running Alertmanager configured in the previous chapter. It creates a Slack notification on all alerts. Let's try to change it so that alerts trigger a remote invocation of the Jenkins job service-scale.

Since Alertmanager configuration is stored as a Docker secret and they are immutable (we cannot update them), we need to remove the service and the secret and create them again.

docker service rm monitor_alert-manager

docker secret rm alert_manager_config

Let us define a Slack config that will send build requests to the service-scale job. The command that creates the service with the configuration is as follows.

echo "route:
 group_by: [service]
 repeat_interval: 1h
 receiver: 'jenkins-go-demo_main'

receivers:
 - name: 'jenkins-go-demo_main'
   webhook_configs:
     - send_resolved: false
       url: 'http://$(docker-machine ip swarm-1)/jenkins/job\
/service-scale/buildWithParameters?token=DevOps22&service=\
go-demo_main&scale...
