The original title is "Kubernetes Health Probes: Liveness, Readiness, and Startup Explained"

Short summary

A practical guide to Kubernetes liveness, readiness, and startup probes, explaining when to use each and common pitfalls. Liveness checks internal process health only—never external dependencies. Readiness controls traffic routing and should reflect external dependency status. Startup probes (added in K8s 1.18) give slow apps time to initialize before liveness kicks in.

• •Liveness probes detect deadlocks; never check external dependencies with them
• •Readiness probes control traffic routing and rolling updates; check DB/cache here
• •Startup probes disable liveness/readiness until initialization completes, solving slow-boot issues
