Once configured with a Slack incoming webhook, Flagger will post messages when a canary deployment has been initialized,
when a new revision has been detected and if the canary analysis failed or succeeded.

A canary deployment will be rolled back if the progress deadline exceeded or if the analysis

Besides Slack, you can use Alertmanager to trigger alerts when a canary deployment failed:
```yaml
- alert: canary_rollback
expr: flagger_canary_status > 1
for: 1m
labels:
severity: warning
annotations:
summary: "Canary failed"
description: "Workload {{ $labels.name }} namespace {{ $labels.namespace }}"
```
