Liveness probes are used to check if an application within a container is still running and responding as expected. If the liveness probe fails, Kubernetes will automatically restart the container, attempting to recover the application. Here's a step-by-step guide on how to set up a liveness probe in Kubernetes: Step 1: Define a Liveness …Learn what liveness is, how it works, and why it matters for biometric security. See examples of spoof artifacts, bypass types, and how to test liveness with FaceTec's …In facial recognition, liveness detection is used to distinguish between a live image and a 2D printed, 3D printed, or digital representation of a user’s face. Other spoof attempts may involve the use of a 3D mask. Spoof attempts can be detected through algorithms that recognize artifacts of a non-live sample, and may use “active ...Liveness probes check if the pod is healthy, and if the pod is deemed unhealthy, it will trigger a restart; this action is different than the action of Readiness Probes I discussed in my previous post.
