# Ansible Role: alertmanager

## Description

Deploy and manage Prometheus [alertmanager](https://github.com/prometheus/alertmanager) service using ansible.

## Requirements

- Ansible >= 2.9 (It might work on previous versions, but we cannot guarantee it)

It would be nice to have prometheus installed somewhere

## Role Variables

All variables which can be overridden are stored in [defaults/main.yml](defaults/main.yml) file as well as in [meta/argument_specs.yml](meta/argument_specs.yml).
Please refer to the [collection docs](https://prometheus-community.github.io/ansible/branch/main/alertmanager_role.html) for description and default values of the variables.

## Example

### Playbook

```yaml
---
  hosts: all
  roles:
    - prometheus.prometheus.alertmanager
  vars:
    alertmanager_version: latest
    alertmanager_slack_api_url: "http://example.com"
    alertmanager_receivers:
      - name: slack
        slack_configs:
          - send_resolved: true
            channel: '#alerts'
    alertmanager_route:
      group_by: ['alertname', 'cluster', 'service']
      group_wait: 30s
      group_interval: 5m
      repeat_interval: 3h
      receiver: slack
```

### Demo site

We provide demo site for full monitoring solution based on prometheus and grafana. Repository with code and links to running instances is [available on github](https://github.com/prometheus/demo-site) and site is hosted on [DigitalOcean](https://digitalocean.com).

## Local Testing

The preferred way of locally testing the role is to use Docker and [molecule](https://github.com/ansible-community/molecule) (v3.x). You will have to install Docker on your system. See "Get started" for a Docker package suitable to for your system. Running your tests is as simple as executing `molecule test`.

## Continuous Integration

Combining molecule and circle CI allows us to test how new PRs will behave when used with multiple ansible versions and multiple operating systems. This also allows use to create test scenarios for different role configurations. As a result we have a quite large test matrix which can take more time than local testing, so please be patient.
