It has 2 different receivers configured: logstash and slack.
How to run it
You need to provide a valid slack api key and logstash endpoint.
Both can be passed to the container as an environmental variable. For example:
docker run \ -e "SLACK_API=https://hooks.slack.com/services/MY/API/KEY" \ -e "LOGSTASH_URL=http://logstash:8080/" \ -e "ALERTMANAGER_URL=https://alertmanager.my.service.url/" basi/alertmanager
You can provide an URL to make work the link in the Slack alerts.
