you can use something like this in prometheus config:

  scrape_interval: 30s
  scrape_timeout: 10s
  evaluation_interval: 30s
  external_labels:
    environment: production```
slack config:
```slack_configs:
  - send_resolved: true
    http_config: {}
    api_url: <secret>
    channel: '#alerts'
    username: '{{ template "slack.default.username" . }}'
    color: '{{ if eq .Status "firing" }}warning{{ else }}good{{ end }}'
    title: '[{{ if eq .Status "firing" }}{{ .Alerts.Firing | len }} {{ end }} {{ if
      eq .Status "firing" }}Alerts{{ else }}{{ .Status | toUpper }}{{ end }}]'
    title_link: '{{ template "slack.default.titlelink" . }}'
    pretext: '{{ .CommonAnnotations.summary }}'
    text: |-
      {{ range .Alerts }}
      {{- if .Annotations.summary }}*Alert:* {{ .Annotations.summary }}{{- end }}
      *Description:* {{ .Annotations.description }}{{ .Annotations.message }}
      *environment:* `{{ .Labels.environment }}`
      *Severity:* `{{ .Labels.severity }}`
      {{ end }}
    footer: '{{ template "slack.default.footer" . }}'
    fallback: '{{ template "slack.default.fallback" . }}'
    callback_id: '{{ template "slack.default.callbackid" . }}'
    icon_emoji: '{{ template "slack.default.iconemoji" . }}'
