Map Alertmanager priorities to Opsgenie

alertmanager-opsgenie-priority-mapping.yaml

receiver:
- name: OpsgenieTeam
  opsgenie_configs:
    - api_url: 'https://api.opsgenie.com/'
      api_key: '<api-key-here>'
      priority: |
        {{ if eq .GroupLabels.severity "critical" }}P2{{ else if eq .GroupLabels.severity "warning" }}P3{{ else if eq .GroupLabels.severity "info" }}P4{{ else }}P5{{ end }}

The above is a standard receiver definition apart from the priority field.

Using Go string templating, we're able to add simple if/else logic that matches Alertmanager priorities (either critical, warning, info or none) and assign them to corresponding P1 through P5 Opsgenie priorities.
