I don't feel so well… Integrating health checks in your .NET Core solutions
summary
Demonstrates concrete .NET Core health checks: adds /health and /ping endpoints, registers checks that return healthy/degraded/unhealthy, and exposes detailed JSON or a simple ping 200/503; integrates HealthChecks.UI and community checks, publishes metrics to Prometheus Pushgateway and displays in Grafana; runs everything in Docker Compose and Kubernetes, uses readiness and liveness probes, and performs a rolling update with three replicas to achieve zero-downtime rolling update; demo exercises failures, shows degraded→unhealthy transitions, Prometheus metrics, and Slack alerts, so the plumbing actually works.
