[Verse 1] In the world of Kubernetes where containers run free Three guardians watch over what we cannot see Liveness checks if your app's still alive and well Readiness says when traffic it can tell Startup gives you time when you're just getting born Before the other probes sound their warning horn [Chorus] Live, Ready, Start - that's the trinity Live, Ready, Start - keeping systems free When your pods are failing, these probes will know Live, Ready, Start - watch your traffic flow Health checks running, status they report Live, Ready, Start - Kubernetes support [Verse 2] Liveness probe will restart you when you're stuck in a loop HTTP get or TCP check, it's part of the group If you fail too many times, the kubelet takes control Kills your container, starts fresh, that's its role Every ten seconds it knocks upon your door "Are you still breathing?" - that's what it's checking for [Chorus] Live, Ready, Start - that's the trinity Live, Ready, Start - keeping systems free When your pods are failing, these probes will know Live, Ready, Start - watch your traffic flow Health checks running, status they report Live, Ready, Start - Kubernetes support [Verse 3] Readiness is different, it won't restart your pod Just removes you from service when things get odd Load balancer stops sending requests your way Until you're healthy and ready for another day Database connecting or cache warming up Readiness waits till you're ready to fill the cup [Bridge] Startup probe runs first when your container wakes Gives you time to initialize, whatever time it takes Once it passes successfully, it steps aside with grace Lets liveness and readiness take over in its place Failure threshold, success count, timeout and delay Configure them wisely for a smooth deployment day [Chorus] Live, Ready, Start - that's the trinity Live, Ready, Start - keeping systems free When your pods are failing, these probes will know Live, Ready, Start - watch your traffic flow Health checks running, status they report Live, Ready, Start - Kubernetes support [Outro] Three probes working together in harmony Observability built into your infrastructure free Live, Ready, Start - remember these three The guardians of your containerized destiny
