Liveness Observer for Services

Lightweight Go library that implements a simple Liveness Probe HTTP endpoint for Kubernetes. Easily plug it into your Go applications to expose health status checks for Google Cloud and any K8s-based deployments. Helps keep your pods healthy and auto-recovering with minimal setup. Ideal for microservices and highload apps that need reliable self-healing in production.

Usage:

// probe will be failed after 15 seconds
probe := liveness.NewProbe(time.Second*15)

service1 := usefulService1.New()
service2 := usefulService2.New()

probe.Watch(service1, service2)

if !probe.IsAlive() {
    panic("observable services are down")
}
