Summary

Enables Alertmanager in the kube-prometheus-stack HelmRelease and configures a Slack receiver so that the committed PrometheusRule alerts (APIHighErrorRate, APIHighLatency, APIDataStale, APIDown) can actually fire and route to Slack.

Changes

  • flux/monitoring/helmrelease.yaml: set alertmanager.enabled: true (was false)
  • Add Slack receiver config reading webhook URL from gatus-slack-webhook secret
  • Add alertmanagerSpec.secrets: [gatus-slack-webhook] so the Alertmanager pod can mount the secret

Validation

  • kustomize build flux/ = PASS

Dependencies

  • Operator must create gatus-slack-webhook secret in monitoring namespace (#73) before Alertmanager can send Slack alerts
  • Depends on Flux being active (#2, #187) for deployment

Closes leeworks-agents/api-company#210
