Introduction​

Continuing our series on setting up Prometheus in a container, this article provides a step-by-step guide for how to configure alerts in Prometheus. We will add alerting rules and deploy Prometheus Alertmanager with Slack integration.

If you follow the steps in this article, you will end up with a containerized setup for:

1. A Prometheus instance with alerting rules.
2. An Alertmanager instance which can send alerts originating from those rules to a Slack channel.

Let's get started.

Introduction​

There are different ways you can use to deploy the Prometheus monitoring tool in your environment. One of the fastest ways to get started is to deploy it as a Docker container. This guide shows you how to quickly set up a minimal Prometheus on your laptop. You can then extend that setup to add a monitoring dashboard, alerting, and authentication.

Deploying Prometheus in a Docker Container​

Basic Setup​

Running Prometheus in Docker is very simple using this command

docker run -p 9000:9090 prometheus prom/prometheus:v3.0.0

This will pull and run the latest version (as of this writing) of Prometheus. You can access the Prometheus UI at localhost:9000. Note that the container port 9090 is forwarded to the localhost port 9000.
